The H8S/2000 has an internal 32-bit architecture, is provided with sixteen 16-bit general registers and a concise, optimized instruction set designed for high-speed operation, and can address a 16-Mbyte linear address space. The instruction set is upward-compatible with H8/300 and H8/300H CPU instructions at the object-code level, facilitating migration from the H8/300, H8/300L, or H8/300H Series. The H8S/2194 Series, and H8S/2194C Series are incorporated with digital servo circuit, ROM, RAM, seven types of timers, three types of PWM, two types of serial communication interface, I2C bus interface, A/D converter, and I/O port as on-chip supporting modules. The on-chip ROM is either flash memory (F-ZTATTM*) or mask ROM, with a capacity of 256, 192, 160, 128, 112, 96, or 80 kbytes. ROM is connected to the CPU via a 16-bit data bus, enabling both byte and word data to be accessed in one state. Instruction fetching has been speeded up, and processing speed increased. The features of the H8S/2194 Series, and H8S/2194C Series are shown in table 1.1. Note: * F-ZTATTM is a trademark of Hitachi, Ltd.

Advanced mode supports a maximum 16-Mbyte total address space (architecturally the maximum total address space is 4 Gbytes, with a maximum of 16 Mbytes for the program area and a maximum of 4 Gbytes for the data area). The mode is selected by the mode pins of the microcontroller. Maximum 64 kbytes for program and data areas combined Normal mode* CPU operating mode Advanced mode Note: * Normal mode is not available for this LSI.

(a) Address Space A maximum address space of 64 kbytes can be accessed. (b) Extended Registers (En) The extended registers (E0 to E7) can be used as 16-bit registers, or as the upper 16-bit segments of 32-bit registers. When En is used as a 16-bit register it can contain any value, even when the corresponding general register (Rn) is used as an address register. If the general register is referenced in the register indirect addressing mode with predecrement (@-Rn) or post-increment (@Rn+) and a carry or borrow occurs, however, the value in the corresponding extended register (En) will be affected. (c) Instruction Set All instructions and addressing modes can be used. Only the lower 16 bits of effective addresses (EA) are valid.

Figure 2.7 CPU Registers Rev. 2.0, 11/00, page 24 of 1037 2.4.2 General Registers The CPU has eight 32-bit general registers. These general registers are all functionally alike and can be used as both address registers and data registers. When a general register is used as a data register, it can be accessed as a 32-bit, 16-bit, or 8-bit register. When the general registers are used as 32-bit registers or address registers, they are designated by the letters ER (ER0 to ER7). The ER registers divide into 16-bit general registers designated by the letters E (E0 to E7) and R (R0 to R7). These registers are functionally equivalent, providing a maximum of sixteen 16-bit registers. The E registers (E0 to E7) are also referred to as extended registers. The R registers divide into 8-bit general registers designated by the letters RH (R0H to R7H) and RL (R0L to R7L). These registers are functionally equivalent, providing a maximum of sixteen 8-bit registers. Figure 2.8 illustrates the usage of the general registers. The usage of each register can be selected independently. Address registers 32-bit registers 16-bit registers 8-bit registers E registers (extended registers) (E0 to E7) ER registers (ER0 to ER7) R registers (R0 to R7) RL registers (R0L to R7L) RH registers (R0H to R7H) Figure 2.8 Usage of General Registers General register ER7 has the function of stack pointer (SP) in addition to its general-register function, and is used implicitly in exception handling and subroutine calls. Figure 2.9 shows the stack. Rev. 2.0, 11/00, page 25 of 1037 Free area SP (ER7) Stack area Figure 2.9 Stack 2.4.3 Control Registers The control registers are the 24-bit program counter (PC), 8-bit extended control register (EXR), and 8-bit condition-code register (CCR). (1) Program Counter (PC) This 24-bit counter indicates the address of the next instruction the CPU will execute. The length of all CPU instructions is 2 bytes (one word), so the least significant PC bit is ignored. (When an instruction is fetched, the least significant PC bit is regarded as 0.) (2) Extended Control Register (EXR) An 8-bit register. In this LSI, this register does not affect operation. Bit 7: Trace Bit (T) This bit is reserved. In this LSI, this bit does not affect operation. Bits 6 to 3: Reserved These bits are reserved. They are always read as 1. Bits 2 to 0: Interrupt Mask Bits (I2 to I0) These bits are reserved. In this LSI, these bits do not affect operation. (3) Condition: Code Register (CCR) This 8-bit register contains internal CPU status information, including an interrupt mask bit (I) and half-carry (H), negative (N), zero (Z), overflow (V), and carry (C) flags. Bit 7: Interrupt Mask Bit (I) Masks interrupts other than NMI when set to 1. (NMI is accepted regardless of the I bit setting.) The I bit is set to 1 by hardware at the start of an exception-handling sequence. For details, see section 6, Interrupt Controller. Rev. 2.0, 11/00, page 26 of 1037 Bit 6: User Bit or Interrupt Mask Bit (UI) Can be written and read by software using the LDC, STC, ANDC, ORC, and XORC instructions. This bit can also be used as an interrupt mask bit. For details, see section 6, Interrupt Controller. Bit 5: Half-Carry Flag (H) When the ADD.B, ADDX.B, SUB.B, SUBX.B, CMP.B, or NEG.B instruction is executed, this flag is set to 1 if there is a carry or borrow at bit 3, and cleared to 0 otherwise. When the ADD.W, SUB.W, CMP.W, or NEG.W instruction is executed, the H flag is set to 1 if there is a carry or borrow at bit 11, and cleared to 0 otherwise. When the ADD.L, SUB.L, CMP.L, or NEG.L instruction is executed, the H flag is set to 1 if there is a carry or borrow at bit 27, and cleared to 0 otherwise. Bit 4: User Bit (U) Can be written and read by software using the LDC, STC, ANDC, ORC, and XORC instructions. Bit 3: Negative Flag (N) Stores the value of the most significant bit (sign bit) of data. Bit 2: Zero Flag (Z) Set to 1 to indicate zero data, and cleared to 0 to indicate non-zero data. Bit 1: Overflow Flag (V) Set to 1 when an arithmetic overflow occurs, and cleared to 0 otherwise. Bit 0: Carry Flag (C) Set to 1 when a carry occurs, and cleared to 0 otherwise. Used by: (a) Add instructions, to indicate a carry (b) Subtract instructions, to indicate a borrow (c) Shift and rotate instructions, to store the carry The carry flag is also used as a bit accumulator by bit-manipulation instructions. Some instructions leave some or all of the flag bits unchanged. For the action of each instruction on the flag bits, see section 29, Appendix A.1, List of Instructions. Operations can be performed on the CCR bits by the LDC, STC, ANDC, ORC, and XORC instructions. The N, Z, V, and C flags are used as branching conditions for conditional branch (Bcc) instructions. 2.4.4 Initial Register Values Reset exception handling loads the CPU's program counter (PC) from the vector table, clears the trace bit in EXR to 0, and sets the interrupt mask bits in CCR and EXR to 1. The other CCR bits and the general registers are not initialized. In particular, the stack pointer (ER7) is not initialized. The stack pointer should therefore be initialized by an MOV.L instruction executed immediately after a reset. Rev. 2.0, 11/00, page 27 of 1037 2.5 Data Formats The CPU can process 1-bit, 4-bit (BCD), 8-bit (byte), 16-bit (word), and 32-bit (longword) data. Bit-manipulation instructions operate on 1-bit data by accessing bit n (n = 0, 1, 2, ..., 7) of byte operand data. The DAA and DAS decimal-adjust instructions treat byte data as two digits of 4bit BCD data. 2.5.1 General Register Data Formats Figure 2.10 shows the data formats in general registers.

The CPU can access word data and longword data in memory, but word or longword data must begin at an even address. If an attempt is made to access word or longword data at an odd address, no address error occurs but the least significant bit of the address is regarded as 0, so the access starts at the preceding address. This also applies to instruction fetches.

An instruction consists of an operation field (op field), a register field (r field), an effective address extension (EA field), and a condition field (cc). Figure 2.12 shows examples of instruction formats. (1) Operation field only op NOP, RTS, etc. (2) Operation field and register fields op rn rm ADD.B Rn, Rm, etc. (3) Operation field, register fields, and effective address extension op EA (disp) (4) Operation field, effective address extension, and condition field op cc EA (disp) BRA d:16, etc. rn rm MOV.B@(d:16, Rn), Rm, etc. Figure 2.12 Instruction Formats (Examples) (1) Operation Field Indicates the function of the instruction, the addressing mode, and the operation to be carried out on the operand. The operation field always includes the first four bits of the instruction. Some instructions have two operation fields. (2) Register Field Specifies a general register. Address registers are specified by 3 bits, data registers by 3 bits or 4 bits. Some instructions have two register fields. Some have no register field. (3) Effective Address Extension Eight, 16, or 32 bits specifying immediate data, an absolute address, or a displacement. (4) Condition Field Specifies the branching condition of Bcc instructions. Rev. 2.0, 11/00, page 43 of 1037 2.6.5 Notes on Use of Bit-Manipulation Instructions The BSET, BCLR, BNOT, BST, and BIST instructions read a byte of data, carry out bit manipulation, then write back the byte of data. Caution is therefore required when using these instructions on a register containing write-only bits, or a port. The BCLR instruction can be used to clear internal I/O register flags to 0. In this case, the relevant flag need not be read beforehand if it is clear that it has been set to 1 in an interrupt handling routine, etc. Rev. 2.0, 11/00, page 44 of 1037 2.7 2.7.1 Addressing Modes and Effective Address Calculation Addressing Mode The CPU supports the eight addressing modes listed in table 2.11. Each instruction uses a subset of these addressing modes. Arithmetic and logic instructions can use the register direct and immediate modes. Data transfer instructions can use all addressing modes except programcounter relative and memory indirect. Bit-manipulation instructions use register direct, register indirect, or absolute addressing mode to specify an operand, and register direct (BSET, BCLR, BNOT, and BTST instructions) or immediate (3-bit) addressing mode to specify a bit number in the operand. Table 2.11 Addressing Modes No. 1 2 3 4 5 6 7 8 Addressing Mode Register direct Register indirect Register indirect with displacement Register indirect with post-increment Register indirect with pre-decrement Absolute address Immediate Program-counter relative Memory indirect Symbol Rn @ERn @(d:16,ERn)/@(d:32,ERn) @ERn+ @-ERn @aa:8/#@aa:16/@aa:24/@aa:32 #xx:8/#xx:16/#xx:32 @(d:8,PC)/@(d:16,PC) @@aa:8 (1) Register Direct-Rn The register field of the instruction code specifies an 8-, 16-, or 32-bit general register containing the operand. R0H to R7H and R0L to R7L can be specified as 8-bit registers. R0 to R7 and E0 to E7 can be specified as 16-bit registers. ER0 to ER7 can be specified as 32bit registers. (2) Register Indirect-@Ern The register field of the instruction code specifies an address register (ERn) which contains the address of the operand in memory. If the address is a program instruction address, the lower 24 bits are valid and the upper 8 bits are all assumed to be 0 (H'00). (3) Register Indirect with Displacement-@(d:16, ERn) or @(d:32, ERn) A 16-bit or 32-bit displacement contained in the instruction is added to an address register (ERn) specified by the register field of the instruction, and the sum gives the address of a memory operand. A 16-bit displacement is sign-extended when added. Rev. 2.0, 11/00, page 45 of 1037 (4) Register Indirect with Post-Increment or Pre-Decrement-@ERn+ or @-ERn (a) Register indirect with post-increment-@ERn+ The register field of the instruction code specifies an address register (ERn) which contains the address of a memory operand. After the operand is accessed, 1, 2, or 4 is added to the address register contents and the sum is stored in the address register. The value added is 1 for byte access, 2 for word access, or 4 for longword access. For word or longword access, the register value should be even. (b) Register indirect with pre-decrement-@-ERn The value 1, 2, or 4 is subtracted from an address register (ERn) specified by the register field in the instruction code, and the result becomes the address of a memory operand. The result is also stored in the address register. The value subtracted is 1 for byte access, 2 for word access, or 4 for longword access. For word or longword access, the register value should be even. (5) Absolute Address-@aa:8, @aa:16, @aa:24, or @aa:32 The instruction code contains the absolute address of a memory operand. The absolute address may be 8 bits long (@aa:8), 16 bits long (@aa:16), 24 bits long (@aa:24), or 32 bits long (@aa:32). To access data, the absolute address should be 8 bits (@aa:8), 16 bits (@aa:16), or 32 bits (@aa:32) long. For an 8-bit absolute address, the upper 24 bits are all assumed to be 1 (H'FFFF). For a 16-bit absolute address the upper 16 bits are a sign extension. A 32-bit absolute address can access the entire address space. A 24-bit absolute address (@aa:24) indicates the address of a program instruction. The upper 8 bits are all assumed to be 0 (H'00). Table 2.12 indicates the accessible absolute address ranges. Table 2.12 Absolute Address Access Ranges Absolute Address Data address 8 bits (@aa:8) 16 bits (@aa:16) 32 bits (@aa:32) Program instruction address 24 bits (@aa:24) Normal Mode H'FF00 to H'FFFF H'0000 to H'FFFF Advanced Mode H'FFFF00 to H'FFFFFF H'000000 to H007FFF, H'FF8000 to H'FFFFFF H'000000 to H'FFFFFF Rev. 2.0, 11/00, page 46 of 1037 (6) Immediate-#xx:8, #xx:16, or #xx:32 The instruction contains 8-bit (#xx:8), 16-bit (#xx:16), or 32-bit (#xx:32) immediate data as an operand. The ADDS, SUBS, INC, and DEC instructions contain immediate data implicitly. Some bit manipulation instructions contain 3-bit immediate data in the instruction code, specifying a bit number. The TRAPA instruction contains 2-bit immediate data in its instruction code, specifying a vector address. (7) Program-Counter Relative-@(d:8, PC) or @(d:16, PC) This mode is used in the Bcc and BSR instructions. An 8-bit or 16-bit displacement contained in the instruction is sign-extended and added to the 24-bit PC contents to generate a branch address. Only the lower 24 bits of this branch address are valid; the upper 8 bits are all assumed to be 0 (H'00). The PC value to which the displacement is added is the address of the first byte of the next instruction, so the possible branching range is -126 to +128 bytes (-63 to +64 words) or -32766 to +32768 bytes (-16383 to +16384 words) from the branch instruction. The resulting value should be an even number. (8) Memory Indirect-@@aa:8 This mode can be used by the JMP and JSR instructions. The instruction code contains an 8bit absolute address specifying a memory operand. This memory operand contains a branch address. The upper bits of the absolute address are all assumed to be 0, so the address range is 0 to 255 (H'0000 to H'00FF in normal mode, H'000000 to H'0000FF in advanced mode). In normal mode the memory operand is a word operand and the branch address is 16 bits long. In advanced mode the memory operand is a longword operand, the first byte of which is assumed to be all 0 (H'00). Note that the first part of the address range is also the exception vector area. For further details, see section 5, Exception Handling. Specified by @aa:8 Branch address Specified by @aa:8 Reserved Branch address (a) Normal Mode (b) Advanced Mode Figure 2.13 Branch Address Specification in Memory Indirect Mode Rev. 2.0, 11/00, page 47 of 1037 If an odd address is specified in word or longword memory access, or as a branch address, the least significant bit is regarded as 0, causing data to be accessed or an instruction code to be fetched at the address preceding the specified address.

Rev. 2.0, 11/00, page 51 of 1037 2.8 2.8.1 Processing States Overview The CPU has four main processing states: the reset state, exception-handling state, program execution state, and power-down state. Figure 2.14 shows a diagram of the processing states. Figure 2.15 indicates the state transitions. Reset state The CPU and all on-chip supporting modules have been initialized and are stopped. Exception-handling state A transient state in which the CPU changes the normal processing flow in response to a reset, interrupt or trap instruction. Processing states Program execution state The CPU executes program instructions in sequence. Sleep mode Power-down state CPU operation is stopped to conserve power.* Standby mode Note: * The power-down state also includes a medium-speed mode, modue stop mode, sub-active mode, sub-sleep mode and watch mode.

From any state, a transition to the reset state occurs whenever RES goes low. A transition can also be made to the reset state when the watchdog timer overflows. 2. The power-down state also includes a watch mode, subactive mode, subsleep mode, etc. For details, see section 4, Power-Down State. Figure 2.15 State Transitions 2.8.2 Reset State When the #$ input goes low all current processing stops and the CPU enters the reset state. All interrupts are disabled in the reset state. Reset exception handling starts when the #$ signal changes from low to high. The reset state can also be entered by a watchdog timer overflow. For details, see section 17, Watchdog Timer. Rev. 2.0, 11/00, page 53 of 1037 2.8.3 Exception-Handling State The exception-handling state is a transient state that occurs when the CPU alters the normal processing flow due to a reset, interrupt, or trap instruction. The CPU fetches a start address (vector) from the exception vector table and branches to that address. (1) Types of Exception Handling and Their Priority Exception handling is performed for resets, interrupts, and trap instructions. Table 2.14 indicates the types of exception handling and their priority. Trap instruction exception handling is always accepted in the program execution state. Exception handling and the stack structure depend on the interrupt control mode set in SYSCR. Table 2.14 Exception Handling Types and Priority Priority High Type of Exception Reset Detection Timing Synchronized with clock Start of Exception Handling Exception handling starts immediately after a low-to-high transition at the #$ pin, or when the watchdog timer overflows When an interrupt is requested, exception handling starts at the end of the current instruction or current exception-handling sequence Exception handling starts when a trap (TRAPA) instruction is executed*2 Interrupt End of instruction execution or end of exception-handling sequence*1 When TRAPA instruction is executed Low Trap instruction Notes: 1. Interrupts are not detected at the end of the ANDC, ORC, XORC, and LDC instructions, or immediately after reset exception handling. 2. Trap instruction exception handling is always accepted in the program execution state. (2) Reset Exception Handling After the #$ pin has gone low and the reset state has been entered, when #$ goes high again, reset exception handling starts. When reset exception handling starts the CPU fetches a start address (vector) from the exception vector table and starts program execution from that address. All interrupts, including NMI, are disabled during reset exception handling and after it ends. (3) Interrupt Exception Handling and Trap Instruction Exception Handling When interrupt or trap-instruction exception handling begins, the CPU references the stack pointer (ER7) and pushes the program counter and other control registers onto the stack. Next, the CPU alters the settings of the interrupt mask bits in the control registers. Then the CPU fetches a start address (vector) from the exception vector table and program execution starts from that start address. Figure 2.16 shows the stack after exception handling ends.

Figure 2.16 Stack Structure after Exception Handling (Examples) 2.8.4 Program Execution State In this state the CPU executes program instructions in sequence. Rev. 2.0, 11/00, page 55 of 1037 2.8.5 Power-Down State The power-down state includes both modes in which the CPU stops operating and modes in which the CPU does not stop. There are five modes in which the CPU stops operating: sleep mode, standby mode, subsleep mode, and watch mode. There are also three other power-down modes: medium-speed mode, module stop mode, and subactive mode. In medium-speed mode, the CPU operates on a medium-speed clock. Module stop mode permits halting of the operation of individual modules, other than the CPU. Subactive mode, subsleep mode, and watch mode are power-down modes that use subclock input. For details, see section 4, Power-Down State. (1) Sleep Mode A transition to sleep mode is made if the SLEEP instruction is executed while the software standby bit (SSBY) in the standby control register (SBYCR) and the LSON bit in the lowpower control register (LPWRCR) are both cleared to 0. In sleep mode, CPU operations stop immediately after execution of the SLEEP instruction. The contents of CPU registers are retained. (2) Standby Mode A transition to standby mode is made if the SLEEP instruction is executed while the SSBY bit in SBYCR is set to 1 and the LSON bit in LPWRCR and the TMA3 bit in the TMA (timer A) are both cleared to 0. In standby mode, the CPU and clock halt and all MCU operations stop. As long as a specified voltage is supplied, the contents of CPU registers and on-chip RAM are retained. Rev. 2.0, 11/00, page 56 of 1037 2.9 2.9.1 Basic Timing Overview The CPU is driven by a system clock, denoted by the symbol . The period from one rising edge of to the next is referred to as a "state." The memory cycle or bus cycle consists of one or two states. Different methods are used to access on-chip memory and on-chip supporting modules. 2.9.2 On-Chip Memory (ROM, RAM) On-chip memory is accessed in one state. The data bus is 16 bits wide, permitting both byte and word transfer instruction. Figure 2.17 shows the on-chip memory access cycle. Bus cycle T1 Internal address bus Internal read signal Read access Internal data bus Internal write signal Write access Internal data bus Address Read data Write data Figure 2.17 On-Chip Memory Access Cycle Rev. 2.0, 11/00, page 57 of 1037 2.9.3 On-Chip Supporting Module Access Timing The on-chip supporting modules are accessed in two states. The data bus is either 8 bits or 16 bits wide, depending on the particular internal I/O register being accessed. Figure 2.18 shows the access timing for the on-chip supporting modules. Bus cycle T1 T2 Internal address bus Internal read signal Read access Internal data bus Internal write signal Write access Internal data bus Address Read data Write data Figure 2.18 On-Chip Supporting Module Access Cycle 2.10 Usage Note Only register ER0, ER1, ER4, or ER5 should be used when using the TAS instruction. The TAS instruction is not generated by the Hitachi H8S or H8/300 series C/C++ compilers. If the TAS instruction is used as a user-defined intrinsic function, ensure that only register ER0, ER1, ER4, or ER5 is used. Rev. 2.0, 11/00, page 58 of 1037 Section 3 MCU Operating Modes 3.1 3.1.1 Overview Operating Mode Selection This LSI has one operating mode (mode 1). This mode is selected depending on settings of the mode pin (MD0). Table 3.1 lists the MCU operating modes. Table 3.1 MCU Operating Mode Selection MD0 0 1 CPU Operating Mode Advanced Description Single-chip mode MCU Operating Mode 0 1 The CPU's architecture allows for 4 Gbytes of address space, but this LSI actually accesses a maximum of 16 Mbytes. Mode 1 operation starts in single-chip mode after reset release. This LSI can only be used in mode 1. This means that the mode pins must be set at mode 1. Do not changes the inputs at the mode pins during operation. 3.1.2 Register Configuration This LSI has a mode control register (MDCR) that indicates the inputs at the mode pin (MD0) and a system control register (SYSCR) and that controls the operation of this LSI. Table 3.2 summarizes these registers.

Low-power operation can be achieved by individually controlling the CPU, on-chip supporting modules, and so on. This LSI operating modes are as follows: 1. 2. 3. 4. 5. 6. 7. 8. High-speed mode Medium-speed mode Subactive mode Sleep mode Subsleep mode Watch mode Module stop mode Standby mode Of these, 2 to 8 are power-down modes. Certain combinations of these modes can be set. After a reset, the MCU is in high-speed mode. Table 4.1 shows the internal chip states in each mode, and table 4.2 shows the conditions for transition to the various modes. Figure 4.1 shows a mode transition diagram.

The operation mode to which the MCU is transited after SLEEP instruction execution is determined by the combination with other control bits than this bit. For details, see the description of Clock Select 2 to 0 in section 12.2.1, Timer Mode Register A.

MSTPCR is initialized to H'FFFF by a reset. MSTRCRH and MSTPCRL Bits 7 to 0: Module Stop (MSTP 15 to MSTP 0) These bits specify module stop mode. See table 4.4 for the method of selecting on-chip supporting modules. MSTPCRH, MSTPCRL Bits 7 to 0 MSTP 15 to MSTP 0 0 1 Description Module stop mode is cleared Module stop mode is set (Initial value) Rev. 2.0, 11/00, page 77 of 1037 4.3 Medium-Speed Mode When the SCK1 and SCK0 bits in SBYCR are set to 1 in high-speed mode, the operating mode changes to medium-speed mode at the end of the bus cycle. In medium-speed mode, the CPU operates on the operating clock (16, 32 or 64) specified by the SCK1 and SCK0 bits. The on-chip supporting modules other than the CPU always operate on the high-speed clock (). In medium-speed mode, a bus access is executed in the specified number of states with respect to the bus master operating clock. For example, if 16 is selected as the operating clock, onchip memory is accessed in 16 states, and internal I/O registers in 32 states. Medium-speed mode is cleared by clearing the both bits SCK1 and SCK0 to 0. A transition is made to high-speed mode and medium-speed mode is cleared at the end of the current bus cycle. If a SLEEP instruction is executed when the SSBY bit in SBYCR and the LSON bit in LPWRCR are cleared to 0, a transition is made to sleep mode. When sleep mode is cleared by an interrupt, medium-speed mode is restored. If a SLEEP instruction is executed when the SSBY bit in SBYCR is set to 1, and the LSON bit in LPWRCR and the TMA3 bit in TMA (Timer A) are both cleared to 0, a transition is made to software standby mode. When standby mode is cleared by an external interrupt, medium-speed mode is restored. When the 5(6 pin is driven low, a transition is made to the reset state, and medium-speed mode is cleared. The same applies in the case of a reset caused by overflow of the watchdog timer. Figure 4.2 shows the timing for transition to and clearance of medium-speed mode.

In sleep mode, CPU operation stops but the contents of the CPU's internal registers are retained. Other supporting modules (excluding the servo circuit and 12-bit PWM) do not stop. 4.4.2 Clearing Sleep Mode Sleep mode is cleared by any interrupt, or with the 5(6 pin. (1) Clearing with an Interrupt When an interrupt request signal is input, sleep mode is cleared and interrupt exception handling is started. Sleep mode will not be cleared if interrupts are disabled, or if interrupts other than NMI have been masked by the CPU. (2) Clearing with the 5(6 Pin When the 5(6 pin is driven low, the reset state is entered. When the 5(6 pin is driven high after the prescribed reset input period, the CPU begins reset exception handling. Rev. 2.0, 11/00, page 79 of 1037 4.5 4.5.1 Module Stop Mode Module Stop Mode Module stop mode can be set for individual on-chip supporting modules. When the corresponding MSTP bit in MSTPCR is set to 1, module operation stops at the end of the bus cycle and a transition is made to module stop mode. The CPU continues operating independently. Table 4.4 shows MSTP bits and the on-chip supporting modules. When the corresponding MSTP bit is cleared to 0, module stop mode is cleared and the module starts operating again at the end of the bus cycle. In module stop mode, the internal states of modules other than the SCI1, A/D converter, Timer X1, and Servo circuit, are retained. After reset release, all modules are in module stop mode. When an on-chip supporting module is in module stop mode, read/write access to its registers is disabled.

In this mode, the CPU, on-chip supporting modules, and oscillator (except for subclock oscillator) all stop. However, contents of the CPU's internal registers and data in the built-in RAM as well as functions of the SCII, timer X1 and built-in peripheral circuits (except the servo circuit) are maintained in the current state. The I/O port, at this time, is caused to the high impedance state. In this mode the oscillator stops, and therefore power dissipation is significantly reduced. 4.6.2 Clearing Standby Mode Standby mode is cleared by an external interrupt (NMI pin, or pin ,54 to ,54, or by means of the 5(6 pin. (1) Clearing with an Interrupt When an NMI, ,54 to ,54 interrupt request signal is input, clock oscillation starts, and after the elapse of the time set in bits STS2 to STS0 in SYSCR, stable clocks are supplied to the entire chip, standby mode is cleared, and interrupt exception handling is started. Standby mode cannot be cleared with an ,54 to ,54 interrupt if the corresponding enable bit has been cleared to 0 or has been masked by the CPU. (2) Clearing with the 5(6 Pin When the 5(6 pin is driven low, clock oscillation is started. At the same time as clock oscillation starts, clocks are supplied to the entire chip. Note that the 5(6 pin must be held low until clock oscillation stabilizes. When the 5(6 pin goes high, the CPU begins reset exception handling. 4.6.3 Setting Oscillation Settling Time after Clearing Standby Mode Bits STS2 to STS0 in SBYCR should be set as described below. (1) Using a Crystal Oscillator Set bits STS2 to STS0 so that the standby time is at least 10 ms (the oscillation settling time). Table 4.5 shows the standby times for different operating frequencies and settings of bits STS2 to STS0.

Note: 1. With Flash memory version, do not set the standby time to 16 states. The standby time is 32 states when transited to medium-speed mode /32 (SCK1 = 1, SCK0 = 0). Rev. 2.0, 11/00, page 82 of 1037 4.7 4.7.1 Watch Mode Watch Mode If a SLEEP instruction is executed in high-speed mode, medium-speed mode or subactive mode when the SSBY in SBYCR is set to 1, the DTON bit in LPWRCR is cleared to 0, and the TMA3 bit in TMA (Timer A) is set to 1, the CPU makes a transition to watch mode. In this mode, the CPU and all on-chip supporting modules except Timer A stop. As long as the prescribed voltage is supplied, the contents of some of the CPU's internal registers and on-chip RAM are retained, and I/O ports are placed in the high-impedance state. 4.7.2 Clearing Watch Mode Watch mode is cleared by an interrupt (Timer A interrupt, NMI pin, or pin ,54 to ,54), or by means of the 5(6 pin. (1) Clearing with an Interrupt When an interrupt request signal is input, watch mode is cleared and a transition is made to high-speed mode or medium-speed mode if the LSON bit in LPWRCR is cleared to 0, or to subactive mode if the LSON bit is set to 1. When making a transition to medium-speed mode, after the elapse of the time set in bits STS2 to STS0 in SBYCR, stable clocks are supplied to the entire chip, and interrupt exception handling is started. Watch mode cannot be cleared with an ,54 to ,54 interrupt if the corresponding enable bit has been cleared to 0, or with an on-chip supporting module interrupt if acceptance of the relevant interrupt has been disabled by the interrupt enable register or masked by the CPU. See section 4.6.3, Setting Oscillation Settling Time after Clearing Standby Mode, for the oscillation settling time setting when making a transition from watch mode to high-speed mode.

Rev. 2.0, 11/00, page 83 of 1037 4.8 4.8.1 Subsleep Mode Subsleep Mode If a SLEEP instruction is executed in subactive mode when the SSBY in SBYCR is cleared to 0, the LSON bit in LPWRCR is set to 1, and the TMA3 bit in TMA (Timer A) is set to 1, the CPU makes a transition to subsleep mode. In this mode, the CPU and all on-chip supporting modules other than Timer A stop. As long as the prescribed voltage is supplied, the contents of the CPU, some of its on-chip registers and onchip RAM are retained, and I/O ports retain their states prior to the transition. 4.8.2 Clearing Subsleep Mode Subsleep mode is cleared by an interrupt (Timer A interrupt, NMI pin, or pin ,54 to ,54), or by means of the 5(6 pin. (1) Clearing with an Interrupt When an interrupt request signal is input, subsleep mode is cleared and interrupt exception handling is started. Subsleep mode cannot be cleared with an ,54 to ,54 interrupt if the corresponding enable bit has been cleared to 0, or with an on-chip supporting module interrupt if acceptance of the relevant interrupt has been disabled by the interrupt enable register or masked by the CPU. (2) Clearing with the 5(6 Pin See (2) Clearing with the 5(6 Pin in section 4.6.2, Clearing Standby Mode. Rev. 2.0, 11/00, page 84 of 1037 4.9 4.9.1 Subactive Mode Subactive Mode If a SLEEP instruction is executed in high-speed mode when the SSBY bit in SBYCR, the DTON bit in LPWRCR, and the TMA3 bit in TMA (Timer A) are all set to 1, the CPU makes a transition to subactive mode. When an interrupt is generated in watch mode, if the LSON bit in LPWRCR is set to 1, a transition is made to subactive mode. When an interrupt is generated in subsleep mode, a transition is made to subactive mode. In subactive mode, the CPU performs sequential program execution at low speed on the subclock. In this mode, all on-chip supporting modules other than Timer A stop. 4.9.2 Clearing Subactive Mode Subsleep mode is cleared by a SLEEP instruction, or by means of the 5(6 pin. (1) Clearing with a SLEEP Instruction When a SLEEP instruction is executed while the SSBY bit in SBYCR is set to 1, the DTON bit in LPWRCR is cleared to 0, and the TMA3 bit in TMA (Timer A) is set to 1, subactive mode is cleared and a transition is made to watch mode. When a SLEEP instruction is executed while the SSBY bit in SBYCR is cleared to 0, the LSON bit in LPWRCR is set to 1, and the TMA3 bit in TMA (Timer A) is set to 1, a transition is made to subsleep mode. When a SLEEP instruction is executed while the SSBY bit in SBYCR is set to 1, the DTON bit is set to 1 and the LSON bit is cleared to 0 in LPWRCR, and the PSS bit in TCSR (WDT1) is set to 1, a transition is made directly to high-speed or medium-speed mode. Fort details of direct transition, see section 4.10, Direct Transition. (2) Clearing with the 5(6 Pin See (2) Clearing with the 5(6 Pin in section 4.6.2, Clearing Standby Mode. Rev. 2.0, 11/00, page 85 of 1037 4.10 4.10.1 Direct Transition Overview of Direct Transition There are three operating modes in which the CPU executes programs: high-speed mode, medium-speed mode, and subactive mode. A transition between high-speed mode and subactive mode without halting the program* is called a direct transition. A direct transition can be carried out by setting the DTON bit in LPWRCR to 1 and executing a SLEEP instruction. After the transition, direct transition interrupt exception handling is started. (1) Direct Transition from High-Speed Mode to Subactive Mode If a SLEEP instruction is executed in high-speed mode while the SSBY bit in SBYCR, the LSON bit and DTON bit in LPWRCR, and the TMA3 bit in TMA (Timer A) are all set to 1, a transition is made to subactive mode. (2) Direct Transition from Subactive Mode to High-Speed Mode/Medium-Speed Mode If a SLEEP instruction is executed in subactive mode while the SSBY bit in SBYCR is set to 1, the LSON bit is cleared to 0 and the DTON bit is set to 1 in LPWRCR, and the TMA3 bit in TMA (Timer A) is set to 1, after the elapse of the time set in bits STS2 to STS0 in SBYCR, a transition is made to directly to high-speed mode. Note: * At the time of transition from subactive mode to high- or medium-speed mode, an oscillation stabilization wait time is generated. Rev. 2.0, 11/00, page 86 of 1037 Section 5 Exception Handling 5.1 5.1.1 Overview Exception Handling Types and Priority As table 5.1 indicates, exception handling may be caused by a reset, trap instruction, or interrupt. Exception handling is prioritized as shown in table 5.1. If two or more exceptions occur simultaneously, they are accepted and processed in order of priority. Trap instruction exceptions are accepted at all times in the program execution state. Exception handling sources, the stack structure, and the operation of the CPU vary depending on the interrupt control mode set by the INTM0 and INTM1 bits in SYSCR. Table 5.1 Priority High Exception Types and Priority Exception Type Reset Trace*1 Interrupt Direct transition Trap instruction (TRAPA)*3 Start of Exception Handling Starts immediately after a low-to-high transition at the #$ pin, or when the watchdog timer overflows Starts when execution of the current instruction or exception handling ends, if the trace (T) bit is set to 1 Starts when execution of the current instruction or exception handling ends, if an interrupt request has been issued*2 Started by a direct transition resulting from execution of a SLEEP instruction Started by execution of a trap instruction (TRAPA) Low Notes: 1. Traces are enabled only in interrupt control modes 2 and 3. (They cannot be used in this LSI.) Trace exception handling is not executed after execution of an RTE instruction. 2. Interrupt detection is not performed on completion of ANDC, ORC, XORC, or LDC instruction execution, or on completion of reset exception handling. 3. Trap instruction exception handling requests are accepted at all times in the program execution state. Rev. 2.0, 11/00, page 87 of 1037 5.1.2 Exception Handling Operation Exceptions originate from various sources. Trap instructions and interrupts are handled as follows: [1] The program counter (PC) and condition-code register (CCR) are pushed onto the stack. [2] The interrupt mask bits are updated. The T bit is cleared to 0. [3] A vector address corresponding to the exception source is generated, and program execution starts from that address. For a reset exception, steps [2] and [3] above are carried out. 5.1.3 Exception Sources and Vector Table The exception sources are classified as shown in figure 5.1. Different vector addresses are assigned to different exception sources. Table 5.2 lists the exception sources and their vector addresses. * Reset * Trace (cannot be used in this LSI) External interrupts ...

Rev. 2.0, 11/00, page 89 of 1037 5.2 5.2.1 Reset Overview A reset has the highest exception priority. When the #$ pin goes low, all processing halts and the MCU enters the reset state. A reset initializes the internal state of the CPU and the registers of on-chip supporting modules. Immediately after a reset, interrupt control mode 0 is set. Reset exception handling begins when the #$ pin changes from low to high. The MCUs can also be reset by overflow of the watchdog timer. For details, see section 17, Watchdog Timer. 5.2.2 Reset Sequence The MCU enters the reset state when the #$ pin goes low. To ensure that the chip is reset, hold the #$ pin low during the oscillation stabilizing time of the clock oscillator when powering on. To reset the chip during operation, hold the #$ pin low for at least 20 states. For pin states in a reset, see Appendix D.1, Pin Circuit Diagrams. When the #$ pin goes high after being held low for the necessary time, the chip starts reset exception handling as follows: [1] The internal state of the CPU and the registers of the on-chip supporting modules are initialized, and the I bit is set to 1 in CCR. [2] The reset exception vector address is read and transferred to the PC, and program execution starts from the address indicated by the PC. Figures 5.2 shows examples of the reset sequence. Rev. 2.0, 11/00, page 90 of 1037 Vector fetch Internal Fetch of first program processing instruction RES Internal address bus (1) (3) Internal read signal Internal write signal High level Internal data bus (2) (4) (1) (2) (3) (4) : Reset exception vector address ((1) = H'0000 or H'000000) : Start address (contents of reset exception vector address) : Start address ((3) = (2)) : First program instruction Figure 5.2 Reset Sequence (Mode 1) 5.2.3 Interrupts after Reset If an interrupt is accepted after a reset but before the stack pointer (SP) is initialized, the PC and CCR will not be saved correctly, leading to a program crash. To prevent this, all interrupt requests, including NMI, are disabled immediately after a reset. Since the first instruction of a program is always executed immediately after the reset state ends, make sure that this instruction initializes the stack pointer (example: MOV.L #xx:32, SP). Rev. 2.0, 11/00, page 91 of 1037 5.3 Interrupts Interrupt exception handling can be requested by seven external sources (NMI and IRQ5 to IRQ0) and internal sources in the on-chip supporting modules. Figure 5.3 shows the interrupt sources and the number of interrupts of each type. The on-chip supporting modules that can request interrupts include the watchdog timer (WDT), prescaler unit (PSU), Timers A, B, J, L, R and X1 (TMR), serial communication interface (SCI), 2 A/D converter (ADC), I C bus interface (IIC), servo circuits, synchronized detection, address trap, etc. Each interrupt source has a separate vector address. NMI is the highest-priority interrupt. Interrupts are controlled by the interrupt controller. The interrupt controller has two interrupt control modes and can assign interrupts other than NMI to either three priority/mask levels to enable multiplexed interrupt control. For details on interrupts, see section 6, Interrupt Controller. NMI (1) External interrupts IRQ5 to IRQ0 (6) WDT* (1) Interrupts PSU (1) TMR (15) SCI (6) Internal interrupts ADC (1) IIC (1) Servo circuits (9) Synchronized detection (1) Address trap (3) Notes: Numbers in parentheses are the numbers of interrupt sources. * When the watchdog timer is used as an interval timer, it generates an interrupt request at each counter overflow. Figure 5.3 Interrupt Sources and Number of Interrupts Rev. 2.0, 11/00, page 92 of 1037 5.4 Trap Instruction Trap instruction exception handling starts when a TRAPA instruction is executed. Trap instruction exception handling can be executed at all times in the program execution state. The TRAPA instruction fetches a start address from a vector table entry corresponding to a vector number from 0 to 3, as specified in the instruction code. Table 5.3 shows the status of CCR and EXR after execution of trap instruction exception handling.

The stack should always be accessed by word transfer instruction or longword transfer instruction, and the value of the stack pointer (SP: ER7) should always be kept even. Use the following instructions to save registers: PUSH.W Rn (or MOV.W Rn, @-SP) PUSH.L ERn (or MOV.L ERn, @-SP) Use the following instructions to restore registers: POP.W Rn (or MOV.W @SP+, Rn) POP.L ERn (or MOV.L @SP+, ERn) Setting SP to an odd value may lead to a malfunction. Figure 5.5 shows an example of what happens when the SP value is odd.

The interrupt controller has the following features: (1) Two Interrupt Control Modes * Either of two interrupt control modes can be set by means of the INTM1 and INTM0 bits in the system control register (SYSCR). (2) Priorities Settable with ICR * An interrupt control register (ICR) is provided for setting interrupt priorities. Three priority levels can be set for each module for all interrupts except NMI. (3) Independent Vector Addresses * All interrupt sources are assigned independent vector addresses, making it unnecessary for the source to be identified in the interrupt handling routine. (4) Seven External Interrupt Pins * NMI is the highest-priority interrupt, and is accepted at all times. Falling edge, rising edge, or both edge detection can be selected for the NMI interrupt. * Falling edge, rising edge, or both edge detection can be selected for interrupt IRQ0. * Falling edge or rising edge can be individually selected for interrupts IRQ5 to IRQ1.

(1) When the port is set as the ,& input pin or ,54 to ,54 input pin, the pin level must be High or Low regardless of active mode or power-down mode. Do not set the pin level at Medium. (2) Switching the pin function of P16/,& or P15/,54 to P10/,54 may be mistakenly identified as edge detection and detection signal may be generated. To prevent this, operate as follows: (a) Set the interrupt enable/disable flag to disable before switching the pin function. (b) Clear the applicable interrupt request flag to 0 after switching the pin function and executing another instruction.

Of these, NMI, and IRQ1 to IRQ0 can be used to restore this chip from standby mode. (1) NMI Interrupt NMI is the highest-priority interrupt, and is always accepted by the CPU regardless of the interrupt control mode and the status of the CPU interrupt mask bits. The NMIEG1 and NMIEG0 bits in SYSCR can be used to select whether an interrupt is requested at a rising, falling edge or both edges on the 10, pin. The vector number for NMI interrupt exception handling is 7. (2) IRQ5 to IRQ0 Interrupts Interrupts IRQ5 to IRQ0 are requested by an input signal at pins ,54 to ,54. Interrupts IRQ5 to IRQ0 have the following features: (a) Using IEGR, it is possible to select whether an interrupt is generated by a low level, falling edge, rising edge, or both edges, at pin ,54. (b) Using IEGR, it is possible to select whether an interrupt is generated by a low level, falling edge, rising edge, or both edges, at pins ,54 to ,54. (c) Enabling or disabling of interrupt requests IRQ5 to IRQ0 can be selected with IENR. (d) The interrupt control level can be set with ICR. (e) The status of interrupt requests IRQ5 to IRQ0 is indicated in IRQR. IRQR flags can be cleared to 0 by software. A block diagram of interrupts IRQ5 to IRQ0 is shown in figure 6.2.

Internal IRQn input pin IRQnF Figure 6.3 Timing of IRQnF Setting The vector numbers for IRQ5 to IRQ0 interrupt exception handling are 21 to 26. Upon detection of IRQ5 to IRQ0 interrupts, the applicable pin is set in the port mode register 1 (PMR1) as ,54Q pin. Rev. 2.0, 11/00, page 107 of 1037 6.3.2 Internal Interrupts There are 38 sources for internal interrupts from on-chip supporting modules. (1) For each on-chip supporting module there are flags that indicate the interrupt request status, and enable bits that select enabling or disabling of these interrupts. If any one of these is set to 1, an interrupt request is issued to the interrupt controller. (2) The interrupt control level can be set by means of ICR. 6.3.3 Interrupt Exception Vector Table Table 6.4 shows interrupt exception handling sources, vector addresses, and interrupt priorities. For default priorities, the lower the vector number, the higher the priority. Priorities among modules can be set by means of ICR. The situation when two or more modules are set to the same priority, and priorities within a module, are fixed as shown in table 6.4.

NMI interrupts and address trap interrupts are accepted at all times except in the reset state. In the case of IRQ interrupts and on-chip supporting module interrupts, an enable bit is provided for each interrupt. Clearing an enable bit to 0 disables the corresponding interrupt request. Interrupt sources for which the enable bits are set to 1 are controlled by the interrupt controller. Table 6.5 shows the interrupt control modes. The interrupt controller performs interrupt control according to the interrupt control mode set by the INTM1 and INTM0 bits in SYSCR, the priorities set in ICR, and the masking state indicated by the I and UI bits in the CPU's CCR. Table 6.5 Interrupt Control Mode 0 Interrupt Control Modes SYSCR INTM1 0 INTM0 0 Priority Setting Register ICR Interrupt Mask Bits I Description Interrupt mask control is performed by the I bit Priority can be set with ICR 3-level interrupt mask control is performed by the I and UI bits Priority can be set with ICR 1 1 ICR I, UI Figure 6.4 shows a block diagram of the priority decision circuit.

Table 6.6 shows the interrupts selected in each interrupt control mode. Table 6.6 Interrupt Control Mode 0 1 Interrupts Selected in Each Interrupt Control Mode Interrupt Mask Bit I 0 1 0 1 UI * * * 0 1 Selected Interrupts All interrupts (control level 1 has priority) NMI and address trap interrupts All interrupts (control level 1 has priority) NMI, address trap and control level 1 interrupts NMI and address trap interrupts Note: * Don't care (2) Default Priority Determination The priority is determined for the selected interrupt, and a vector number is generated. If the same value is set for ICR, acceptance of multiple interrupts is enabled, and so only the interrupt source with the highest priority according to the preset default priorities is selected and has a vector number generated. Interrupt sources with a lower priority than the accepted interrupt source are held pending. Table 6.7 shows operations and control signal functions in each interrupt control mode.

Interrupts are enabled when the I bit is cleared to 0, and disabled when set to 1. Control level 1 interrupt sources have higher priority. Figure 6.5 shows a flowchart of the interrupt acceptance operation in this case. (1) If an interrupt source occurs when the corresponding interrupt enable bit is set to 1, an interrupt request is sent to the interrupt controller. (2) When interrupt requests are sent to the interrupt controller, a control level 1 interrupt, according to the control level set in ICR, has priority for selection, and other interrupt requests are held pending. If a number of interrupt requests with the same control level setting are generated at the same time, the interrupt request with the highest priority according to the priority system shown in table 6.4 is selected. (3) The I bit is then referenced. If the I bit is cleared to 0, the interrupt request is accepted. If the I bit is set to 1, only an NMI or an address trap interrupt is accepted, and other interrupt requests are held pending. (4) When an interrupt request is accepted, interrupt exception handling starts after execution of the current instruction has been completed. (5) The PC and CCR are saved to the stack area by interrupt exception handling. The PC saved on the stack shows the address of the first instruction to be executed after returning from the interrupt handling routine. (6) Next, the I bit in CCR is set to 1. This disables all interrupts except NMI and address trap. (7) A vector address is generated for the accepted interrupt, and execution of the interrupt handling routine starts at the address indicated by the contents of that vector address.

(1) Control level 0 interrupt requests are enabled when the I bit is cleared to 0, and disabled when set to 1. (2) Control level 1 interrupt requests are enabled when the I bit or UI bit is cleared to 0, and disabled when both the I bit and the UI bit are set to 1. For example, if the interrupt enable bit for an interrupt request is set to 1, and H'04, H'00, H'00 and H'00 are set in ICRA, ICRB, ICRC and ICRD respectively, (i.e. IRQ2 interrupt is set to control level 1 and other interrupts to control level 0), the situation is as follows: (1) When I = 0, all interrupts are enabled (Priority order: NMI > IRQ2 > IC > HSW1 > ...) (2) When I = 1 and UI = 0, only NMI, address trap and IRQ2 interrupts are enabled (3) When I = 1 and UI = 1, only NMI and address trap interrupts are enabled Figure 6.6 shows the state transitions in these cases.

(2) When interrupt requests are sent to the interrupt controller, a control level 1 interrupt, according to the control level set in ICR, has priority for selection, and other interrupt requests are held pending. If a number of interrupt requests with the same control level setting are generated at the same time, the interrupt request with the highest priority according to the priority system shown in table 6.4 is selected. (3) The I bit is then referenced. If the I bit is cleared to 0, the UI bit has no effect. An interrupt request set to interrupt control level 0 is accepted when the I bit is cleared to 0. If the I bit is set to 1, only NMI and address trap interrupts are accepted, and other interrupt requests are held pending. An interrupt request set to interrupt control level 1 has priority over an interrupt request set to interrupt control level 0, and is accepted if the I bit is cleared to 0, or if the I bit is set to 1 and the UI bit is cleared to 0. When both the I bit and the UI bit are set to 1, only NMI and address trap interrupts are accepted, and other interrupt requests are held pending. (4) When an interrupt request is accepted, interrupt exception handling starts after execution of the current instruction has been completed. (5) The PC and CCR are saved to the stack area by interrupt exception handling. The PC saved on the stack shows the address of the first instruction to be executed after returning from the interrupt handling routine. (6) Next, the I and UI bits in CCR are set to 1.

In other words, when an interrupt enable bit is cleared to 0 by an instruction such as BCLR or MOV, if an interrupt is generated during execution of the instruction, the interrupt concerned will still be enabled on completion of the instruction, and so interrupt exception handling for that interrupt will be executed on completion of the instruction. However, if there is an interrupt request of higher priority than that interrupt, interrupt exception handling will be executed for the higher-priority interrupt, and the lower-priority interrupt will be ignored. The same also applies when an interrupt source flag is cleared to 0. Figure 6.9 shows an example in which the OCIAE bit in timer X1 TIER is cleared to 0. TIER write cycle by CPU OCIA interrupt exception handling Internal address bus TIER address Internal write signal OCIAE OCFA OCIA interrupt signal Figure 6.9 Contention between Interrupt Generation and Disabling The above contention will not occur if an enable bit or interrupt source flag is cleared to 0 while the interrupt is masked. Rev. 2.0, 11/00, page 120 of 1037 6.5.2 Instructions that Disable Interrupts Instructions that disable interrupts are LDC, ANDC, ORC, and XORC. After any of these instructions is executed, all interrupts except NMI are disabled and the next instruction is always executed. When the I bit or UI bit is set by one of these instructions, the new value becomes valid two states after execution of the instruction ends. 6.5.3 Interrupts during Execution of EEPMOV Instruction Interrupt operation differs between the EEPMOV.B instruction and the EEPMOV.W instruction. With the EEPMOV.B instruction, an interrupt request (including NMI) issued during the transfer is not accepted until the move is completed. With the EEPMOV.W instruction, if an interrupt request is issued during the transfer, interrupt exception handling starts at a break in the transfer cycle. The PC value saved on the stack in this case is the address of the next instruction. Therefore, if an interrupt is generated during execution of an EEPMOV.W instruction, the following coding should be used.

The ROM is connected to the CPU by a 16-bit data bus. The CPU accesses both byte and word data in one state, enabling faster instruction fetches and higher processing speed. The flash memory versions of the H8S/2194 can be erased and programmed on-board as well as with a general-purpose PROM programmer. 7.1.1 Block Diagram Figure 7.1 shows a block diagram of the ROM.

Erasing is performed by block erase (in single-block units). When erasing all blocks, the individual blocks must be erased sequentially. Block erasing can be performed as required on 1-kbyte, 8-kbyte, 16-kbyte, 28kbyte, and 32-kbyte blocks. * Programming/erase times The flash memory programming time is 10 ms (typ.) for simultaneous 32-byte programming, equivalent to 300 s (typ.) per byte, and the erase time is 100 ms (typ.) per block. * Reprogramming capability The flash memory can be reprogrammed up to 100 times. * On-board programming modes There are two modes in which flash memory can be programmed/erased/verified on-board: -- Boot mode -- User program mode * Automatic bit rate adjustment If data transfer on boot mode, automatic adjustment is possible at host transfer bit rates and MCU's bit rates. * Protect modes There are three protect modes, hardware, software, and error protect, which allow protected status to be designated for flash memory program/erase/verify operations. * Programmer mode Flash memory can be programmed/erased in programmer mode, using a PROM programmer, as well as in on-board programming mode.

In user mode, flash memory can be read but not programmed or erased.

Initial state The old program version or data remains written in the flash memory. The user should prepare the programming control program and new application program beforehand in the host. 2. Programming control program transfer When boot mode is entered, the boot program in the LSI (originally incorporated in the chip) is started and the programing control program in the host is transferred to RAM via SCI communication.

FLMCR1 is an 8-bit register used for flash memory operating mode control. Program-verify mode or erase-verify mode is entered by setting SWE to 1 when FWE = 1. Program mode is entered by setting SWE to 1 when FWE = 1, then setting the PSU bit in FLMCR2, and finally setting the P bit. Erase mode is entered by setting SWE to 1 when FWE = 1, then setting the ESU bit in FLMCR2, and finally setting the E bit. FLMCR1 is initialized by a reset, in powerdown state (excluding the medium-speed mode, module stop mode, and sleep mode), or when a low level is input to the FWE pin. Its initial value is H'80 when a high level is input to the FWE pin, and H'00 when a low level is input. When on-chip flash memory is disabled, a read will return H'00, and writes are invalid. Writes to the SWE bit in FLMCR1 are enabled only when FWE = 1; writes to the EV and PV bits only when FWE=1 and SWE=1; writes to the E bit only when FWE = 1, SWE = 1, and ESU = 1; and writes to the P bit only when FWE = 1, SWE = 1, and PSU = 1.

There are two on-board programming modes: boot mode and user program mode. The pin settings for transition to each of these modes are shown in table 7.5. For a diagram of the transitions to the various flash memory modes, see figure 7.3.

In user program mode, the FWE pin should not be constantly set to 1. Set FWE to 1 to make a transition to user program mode before performing a program/erase/verify operation. 2. Can be used as I/O ports after boot mode is initiated. Rev. 2.0, 11/00, page 138 of 1037 7.4.1 Boot Mode When boot mode is used, the flash memory programming control program must be prepared in the host beforehand. The channel 1 SCI to be used is set to asynchronous mode. When a reset-start is executed after the MCU's pins have been set to boot mode, the boot program built into the MCU is started and the programming control program prepared in the host is serially transmitted to the MCU via the SCI1. In the MCU, the programming control program received via the SCI1 is written into the programming control program area in on-chip RAM. After the transfer is completed, control branches to the start address of the programming control program area and the programming control program execution state is entered (flash memory programming is performed). The transferred programming control program must therefore include coding that follows the programming algorithm given later. The system configuration in boot mode is shown in figure 7.7, and the boot program mode execution procedure in figure 7.8.

The SCI transmit/receive format should be set as follows: 8-bit data, 1 stop bit, no parity. The MCU calculates the bit rate of the transmission from the host from the measured low period, and transmits one H'00 byte to the host to indicate the end of bit rate adjustment. The host should confirm that this adjustment end indication (H'00) has been received normally, and transmit one H'55 byte to the MCU. If reception cannot be performed normally, initiate boot mode again (reset), and repeat the above operations. Depending on the host's transmission bit rate and the MCU's system clock frequency, there will be a discrepancy between the bit rates of the host and the MCU. To ensure correct SCI operation, the host's transfer bit rate should be set to (2400, 4800, or 9600) bps. Table 7.6 shows typical host transfer bit rates and system clock frequencies for which automatic adjustment of the MCU's bit rate is possible. The boot program should be executed within this system clock range. Table 7.6 System Clock Frequencies for which Automatic Adjustment of This LSI Bit Rate is Possible System Clock Frequency for which Automatic Adjustment of This LSI Bit Rate is Possible 8 MHz to 10 MHz 4 MHz to 10 MHz Host Bit Rate 9600 bps 4800 bps Rev. 2.0, 11/00, page 141 of 1037 (2) On-Chip RAM Area Divisions in Boot Mode In boot mode, the 2048-byte area from H'FFEFB0 to H'FFF7AF is reserved for use by the boot program, as shown in figure 7.10. The area to which the programming control program is transferred is H'FFF7B0 to H'FFFF2F (1920 bytes). The boot program area can be used when the programming control program transferred into RAM enters the execution state. A stack area should be set up as required. H'FFEFB0 Boot program area* (2048 bytes) H'FFF7B0 Programming control program area (1920 bytes) H'FFFF30 H'FFFFAF Reserved area (128 bytes) Note: * The boot program area cannot be used until a transition is made to the execution state for the programming control program transferred to RAM. Note that the boot program reamins stored in this area after a branch is made to the programming control program. Figure 7.10 RAM Areas in Boot Mode Rev. 2.0, 11/00, page 142 of 1037 (3) Notes on Use of Boot Mode: (a) When reset is released in boot mode, it measures the low period of the input at the SCI1's SI1 pin. The reset should end with SI1 pin high. After the reset ends, it takes about 100 states for the chip to get ready to measure the low period of the SI1 pin input. (b) In boot mode, if any data has been programmed into the flash memory (if all data is not 1), all flash memory blocks are erased. Boot mode is for use when user program mode is unavailable, such as the first time on-board programming is performed, or if the program activated in user program mode is accidentally erased. (c) Interrupts cannot be used while the flash memory is being programmed or erased. (d) The SI1 and SO1 pins should be pulled up on the board. (e) Before branching to the programming control program (RAM area H'FFF3B0), the chip terminates transmit and receive operations by the on-chip SCI (channel 1) (by clearing the RE and TE bits in SCR to 0), but the adjusted bit rate value remains set in BRR. The transmit data output pin, SO1, goes to the high-level output state (P21PCR = 1, P21PDR = 1). The contents of the CPU's internal general registers are undefined at this time, so these registers must be initialized immediately after branching to the programming control program. In particular, since the stack pointer (SP) is used implicitly in subroutine calls, etc., a stack area must be specified for use by the programming control program. The initial values of other on-chip registers are not changed. (f) Boot mode can be entered by making the pin settings shown in table 7.5 and executing a reset-start. When the chip detects the boot mode setting at reset release*1, it retains that state internally. Boot mode can be cleared by driving the reset pin low, waiting at least 20 states, then *1 setting the FWE pin and mode pins, and executing reset release . Boot mode can also be cleared by a WDT overflow reset. If the mode pin input levels are changed in boot mode, the boot mode state will be maintained in the microcomputer, and boot mode continued, unless a reset occurs. However, the FWE pin must not be driven low while the boot program is running or flash *2 memory is being programmed or erased . Notes: 1. Mode pin and FWE pin input must satisfy the mode programming setup time (tMDS = 4 states) with respect to the reset release timing. 2. For further information on FWE application and disconnection, see section 7.9, Flash Memory Programming and Erasing Precautions. Rev. 2.0, 11/00, page 143 of 1037 7.4.2 User Program Mode When set to user program mode, the chip can program and erase its flash memory by executing a user program/erase control program. Therefore, on-board reprogramming of the on-chip flash memory can be carried out by providing on-board means of FWE control and supply of programming data, and storing a program/erase control program in part of the program area as necessary. In this mode, the chip starts up in mode 1 and applies a high level to the FWE pin. The flash memory itself cannot be read while the SWE bit is set to 1 to perform programming or erasing, so the control program that performs programming and erasing should be run in on-chip RAM or external memory. Figure 7.11 shows the procedure for executing the program/erase control program when transferred to on-chip RAM. Write the FWE assessment program and transfer program (and the program/erase control program if necessary) beforehand MD0 = 1 Reset start Transfer program/erase control program to RAM Branch to program/erase control program in RAM area FWE = high * Execute program/erase control program (flash memory rewriting) Clear FWE * Branch to flash memory application program Note: Do not apply a constant high level to the FWE pin. Apply a high level to the FWE pin only when the flash memory is programmed or erased. Also, while a high level is applied to the FWE pin, the watchdog timer should be activated to prevent overprogramming or overerasing due to program runaway, etc. * For further information on FWE application and disconnection, see section 7.9, Flash Memory Programming and Erasing Precautions. Figure 7.11 User Program Mode Execution Procedure Rev. 2.0, 11/00, page 144 of 1037 7.5 Programming/Erasing Flash Memory In the on-board programming modes, flash memory programming and erasing is performed by software, using the CPU. There are four flash memory operating modes: program mode, erase mode, program-verify mode, and erase-verify mode. Transitions to these modes can be made by setting the PSU and ESU bits in FLMCR2, and the P, E, PV, and EV bits in FLMCR1. The flash memory cannot be read while being programmed or erased. Therefore, the program that controls flash memory programming/erasing (the programming control program) should be located and executed in on-chip RAM or external memory. Notes: 1. Operation is not guaranteed if setting/resetting of the SWE, EV, PV, E, and P bits in FLMCR1, and the ESU and PSU bits in FLMCR2, is executed by a program in flash memory. 2. When programming or erasing, set FWE to 1 (programming/erasing will not be executed if FWE = 0). 3. Perform programming in the erased state. Do not perform additional programming on previously programmed addresses. 7.5.1 Program Mode Follow the procedure shown in the program/program-verify flowchart in figure 7.12 to write data or programs to flash memory. Performing program operations according to this flowchart will enable data or programs to be written to flash memory without subjecting the device to voltage stress or sacrificing program data reliability. Programming should be carried out 32 bytes at a time. Table 29.9 in section 29.2.7, Flash Memory Characteristics, lists wait time (x, y, z, , , , and ) after setting or clearing each bit on the flash memory control registers 1 and 2 (FLMCR1 and FLMCR2) and the maximum write count (N). Following the elapse of (x) s or more after the SWE bit is set to 1 in flash memory control register 1 (FLMCR1), 32-byte program data is stored in the program data area and reprogram data area, and the 32-byte data in the reprogram data area written consecutively to the write addresses. The lower 8 bits of the first address written to must be H'00, H'20, H'40, H'60, H'80, H'A0, H'C0, or H'E0. Thirty-two consecutive byte data transfers are performed. The program address and program data are latched in the flash memory. A 32-byte data transfer must be performed even if writing fewer than 32 bytes; in this case, H'FF data must be written to the extra addresses. Next, the watchdog timer is set to prevent overprogramming in the event of program runaway, etc. Set more than (y + z + + ) s as the WDT overflow period. After this, preparation for program mode (program setup) is carried out by setting the PSU bit in FLMCR2, and after the elapse of (y) s or more, the operating mode is switched to program mode by setting the P bit in FLMCR1. The time during which the P bit is set is the flash memory programming time. Make a program setting so that the time for one programming operation is within the range of (z) s. Rev. 2.0, 11/00, page 145 of 1037 7.5.2 Program-Verify Mode In program-verify mode, the data written in program mode is read to check whether it has been correctly written in the flash memory. After the elapse of a given programming time, the programming mode is exited (the P bit in FLMCR1 is cleared, then the PSU bit in FLMCR2 is cleared at least () s later). The watchdog timer is cleared after the elapse of () s or more, and the operating mode is switched to program-verify mode by setting the PV bit in FLMCR1. Before reading in program-verify mode, a dummy write of H'FF data should be made to the addresses to be read. The dummy write should be executed after the elapse of () s or more. When the flash memory is read in this state (verify data is read in 16-bit units), the data at the latched address is read. Wait at least () s after the dummy write before performing this read operation. Next, the originally written data is compared with the verify data, and reprogram data is computed (see figure 7.12) and transferred to the reprogram data area. After 32 bytes of data have been verified, exit programverify mode, wait for at least () s, then clear the SWE bit in FLMCR1. If reprogramming is necessary, set program mode again, and repeat the program/program-verify sequence as before. However, ensure that the program/program-verify sequence is not repeated more than (N) times on the same bits. Rev. 2.0, 11/00, page 146 of 1037 START Set SWE bit in FLMCR1 Wait (x) s Programming must be excuted in the erased state.

A 32-byte data transfer must be performed even if writing fewer than 32 bytes; in this case, H'FF data must be written to the extra addresses. 2. Verify data is read in 16-bit (word) units. 3. Even in case of the bit which is already-programmed in the 32-byte programming loop, perform additional programming if the bit fails at the next verify. 4. An area for storing program data (32 bytes) and reprogram data (32 bytes) must be provided in RAM. The contents of the latter are rewritten as programming progresses. 5.

Table 28.9 in section 28.2.7, Flash Memory Characteristics lists wait time (x, y, z, , , , and ) after setting or clearing each bit on the flash memory control registers 1 and 2 (FLMCR1 and FLMCR2) and the maximum clearing count (N). To perform data or program erasure, make a 1 bit setting for the flash memory area to be erased in erase block register 1 or 2 (EBR1 or EBR2) at least (x) s after setting the SWE bit to 1 in flash memory control register 1 (FLMCR1). Next, the watchdog timer is set to prevent overerasing in the event of program runaway, etc. Set more than (y + z + + ) ms as the WDT overflow period. After this, preparation for erase mode (erase setup) is carried out by setting the ESU bit in FLMCR2, and after the elapse of (y) s or more, the operating mode is switched to erase mode by setting the E bit in FLMCR1. The time during which the E bit is set is the flash memory erase time. Ensure that the erase time does not exceed (z) ms. Note: With flash memory erasing, preprogramming (setting all data in the memory to be erased to 0) is not necessary before starting the erase procedure. 7.5.4 Erase-Verify Mode In erase-verify mode, data is read after memory has been erased to check whether it has been correctly erased. After the elapse of the erase time, erase mode is exited (the E bit in FLMCR1 is cleared, then the ESU bit in FLMCR2 is cleared at least () s later), the watchdog timer is cleared after the elapse of () s or more, and the operating mode is switched to erase-verify mode by setting the EV bit in FLMCR1. Before reading in erase-verify mode, a dummy write of H'FF data should be made to the addresses to be read. The dummy write should be executed after the elapse of () s or more. When the flash memory is read in this state (verify data is read in 16-bit units), the data at the latched address is read. Wait at least () s after the dummy write before performing this read operation. If the read data has been erased (all 1), a dummy write is performed to the next address, and erase-verify is performed. If the read data has not been erased, set erase mode again, and repeat the erase/erase-verify sequence in the same way. However, ensure that the erase/erase-verify sequence is not repeated more than (N) times. When verification is completed, exit erase-verify mode, and wait for at least () s. If erasure has been completed on all the erase blocks, clear the SWE bit in FLMCR1. If there are any unerased blocks, make a 1 bit setting in EBR1 or EBR2 for the flash memory area to be erased, and repeat the erase/eraseverify sequence in the same way.

The values of x, y, z, , , , , and N are listed in section 29.2.7, Flash Memory Characteristics. Verify data is read in 16-bit (word) units. Set only one bit in EBR1 or EBR2. More than one bit cannot be set. Erasing is performed in block units. To erase a number of blocks, the individual blocks must be erased sequentially. Figure 7.13 Erase/Erase-Verify Flowchart (Single-Block Erase) Rev. 2.0, 11/00, page 149 of 1037 7.6 Flash Memory Protection There are three kinds of flash memory program/erase protection: hardware protection, software protection, and error protection. 7.6.1 Hardware Protection Hardware protection refers to a state in which programming/erasing of flash memory is forcibly disabled or aborted. Hardware protection is reset by settings in flash memory control registers 1 and 2 (FLMCR1, FLMCR2) and erase block registers 1 and 2 (EBR1, EBR2). In error protection mode, FLMCR1, FLMCR2, EBR1 and EBR2 settings are retained. (See table 7.7.) Table 7.7 Hardware Protection Functions Item FWE pin protection Reset/standby protection Description * When a low level is input to the FWE pin, FLMCR1, FLMCR2, EBR1, and EBR2 are initialized, and the program/erase-protected state is entered * In a reset (including a WDT overflow reset) and in power-down state (excluding the medium-speed mode, module stop mode, and sleep mode), FLMCR1, FLMCR2 (excluding the FLER bit), EBR1, and EBR2 are initialized, and the program/eraseprotected state is entered * In a reset via the 5(6 pin, the reset state is not entered unless the 5(6 pin is held low until oscillation stabilizes after powering on. In the case of a reset during operation, hold the 5(6 pin low for the 5(6 pulse width specified in the AC characteristics section Program Yes Erase Yes Yes Yes Rev. 2.0, 11/00, page 150 of 1037 7.6.2 Software Protection Software protection can be implemented by setting the SWE bit in FLMCR1 and erase block registers 1 and 2 (EBR1, EBR2). When software protection is in effect, setting the P or E bit in flash memory control register 1 (FLMCR1) does not cause a transition to program mode or erase mode. (See table 7.8.) Table 7.8 Software Protection Functions Item SWE bit protection Block specification protection Description * Clearing the SWE bit to 0 in FLMCR1 sets the program/erase-protected state for all blocks (Execute in on-chip RAM or external memory) * Erase protection can be set for individual blocks by settings in erase block registers 1 and 2 (EBR1, EBR2) * Setting EBR1 and EBR2 to H'00 places all blocks in the erase-protected state Program Yes Erase Yes - Yes Rev. 2.0, 11/00, page 151 of 1037 7.6.3 Error Protection In error protection, an error is detected when MCU runaway occurs during flash memory programming/erasing, or operation is not performed in accordance with the program/erase algorithm, and the program/erase operation is aborted. Aborting the program/erase operation prevents damage to the flash memory due to overprogramming or overerasing. If the MCU malfunctions during flash memory programming/erasing, the FLER bit is set to 1 in FLMCR2 and the error protection state is entered. The FLMCR1, FLMCR2, EBR1, and EBR2 settings are retained, but program mode or erase mode is aborted at the point at which the error occurred. Program mode or erase mode cannot be re-entered by re-setting the P or E bit. However, PV and EV bit setting is enabled, and a transition can be made to verify mode. FLER bit setting conditions are as follows: (1) When flash memory is read during programming/erasing (including a vector read or instruction fetch) (2) Immediately after exception handling (excluding a reset) during programming/erasing (3) When a SLEEP instruction is executed during programming/erasing Error protection is released only by a reset and in hardware standby mode. Figure 7.14 shows the flash memory state transition diagram.

There are three reasons for this: (1) Interrupt during programming or erasing might cause a violation of the programming or erasing algorithm, with the result that normal operation could not be assured. (2) In the interrupt exception handling sequence during programming or erasing, the vector *2 would not be read correctly , possibly resulting in MCU runaway. (3) If interrupt occurred during boot program execution, it would not be possible to execute the normal boot mode sequence. For these reasons, in on-board programming mode alone there are conditions for disabling interrupt, as an exception to the general rule. However, this provision does not guarantee normal erasing and programming or MCU operation. All requests, including NMI input, must therefore be disabled inside and outside the MCU during FWE application. Interrupt is also disabled in the error-protection state while the P or E bit remains set in FLMCR1. Notes: 1. Interrupt requests must be disabled inside and outside the MCU until data write by the write control program is complete. 2. The vector may not be read correctly in this case for the following two reasons: * If flash memory is read while being programmed or erased (while the P or E bit is set in FLMCR1), correct read data will not be obtained (undetermined values will be returned). * If the interrupt entry in the interrupt vector table has not been programmed yet, interrupt exception handling will not be executed correctly. Rev. 2.0, 11/00, page 153 of 1037 7.8 7.8.1 Flash Memory Programmer Mode Programmer Mode Setting Programs and data can be written and erased in programmer mode as well as in the on-board programming modes. In programmer mode, the on-chip ROM can be freely programmed using a PROM programmer that supports Hitachi microcomputer device type with 128-kbyte on-chip flash memory. Flash memory read mode, auto-program mode, auto-erase mode, and status read mode are supported with these device types. In auto-program mode, auto-erase mode, and status read mode, a status polling procedure is used, and in status read mode, detailed internal signals are output after execution of an auto-program or auto-erase operation. 7.8.2 Socket Adapters and Memory Map In programmer mode, a socket adapter is mounted on the writer programmer. The socket adapter product codes are listed in table 7.9. Figure 7.15 shows the memory map in programmer mode.

Details of each mode are given below. (1) Memory Read Mode Memory read mode supports byte reads. (2) Auto-Program Mode Auto-program mode supports programming of 128 bytes at a time. Status polling is used to confirm the end of auto-programming. (3) Auto-Erase Mode Auto-erase mode supports automatic erasing of the entire flash memory. Status polling is used to confirm the end of auto-erasing. (4) Status Read Mode Status polling is used for auto-programming and auto-erasing, and normal termination can be confirmed by reading the FO6 signal. In status read mode, error information is output if an error occurs.

Rev. 2.0, 11/00, page 156 of 1037 7.8.4 Memory Read Mode (1) After the end of an auto-program, auto-erase, or status read operation, the command wait state is entered. To read memory contents, a transition must be made to memory read mode by means of a command write before the read is executed. (2) Command writes can be performed in memory read mode, just as in the command wait state. (3) Once memory read mode has been entered, consecutive reads can be performed. (4) After power-on, memory read mode is entered.

In this case, H'FF data must be written to the extra addresses. (c) The lower 8 bits of the transfer address must be H'00 or H'80. If a value other than an effective address is input, processing will switch to a memory write operation but a write error will be flagged. (d) Memory address transfer is performed in the second cycle (figure 7.20). Do not perform transfer after the second cycle. (e) Do not perform a command write during a programming operation.

(2) When performing programming using programmer mode on a chip that has been programmed/erased in an on-board programming mode, auto-erasing is recommended before carrying out auto-programming. Notes: 1. The flash memory is initially in the erased state when the device is shipped by Hitachi. For other chips for which the erasure history is unknown, it is recommended that auto-erasing be executed to check and supplement the initialization (erase) level. 2. Auto-programming should be performed once only on the same address block. Rev. 2.0, 11/00, page 166 of 1037 7.9 Flash Memory Programming and Erasing Precautions Precautions concerning the use of on-board programming mode and programmer mode are summarized below. (1) Use the Specified Voltages and Timing for Programming and Erasing Applied voltages in excess of the rating can permanently damage the device. Use a PROM programmer that supports Hitachi microcomputer device type with 128-kbyte on-chip flash memory. Do not select the HN28F101 setting for the PROM programmer, and only use the specified socket adapter. Incorrect use will result in damaging the device. (2) Powering On and Off Do not apply a high level to the FWE pin until VCC has stabilized. Also, drive the FWE pin low before turning off VCC. When applying or disconnecting VCC, fix the FWE pin low and place the flash memory in the hardware protection state. The power-on and power-off timing requirements should also be satisfied in the event of a power failure and subsequent recovery. (3) FWE Application/Disconnection FWE application should be carried out when MCU operation is in a stable condition. If MCU operation is not stable, fix the FWE pin low and set the protection state. The following points must be observed concerning FWE application and disconnection to prevent unintentional programming or erasing of flash memory: (a) Apply FWE when the VCC voltage has stabilized within its rated voltage range. (b) In boot mode, apply and disconnect FWE during a reset. (c) In user program mode, FWE can be switched between high and low level regardless of the reset state. FWE input can also be switched during program execution in flash memory. (d) Do not apply FWE if program runaway has occurred. (e) Disconnect FWE only when the SWE, ESU, PSU, EV, PV, P, and E bits in FLMCR1 and FLMCR2 are cleared. Make sure that the SWE, ESU, PSU, EV, PV, P, and E bits are not set by mistake when applying or disconnecting FWE. (4) Do Not Apply a Constant High Level to the FWE Pin Apply a high level to the FWE pin only when programming or erasing flash memory. A system configuration in which a high level is constantly applied to the FWE should be avoided. Also, while a high level is applied to the FWE pin, the watchdog timer should be activated to prevent overprogramming or overerasing due to program runaway, etc. Rev. 2.0, 11/00, page 167 of 1037 (5) Use the Recommended Algorithm when Programming and Erasing Flash Memory The recommended algorithm enables programming and erasing to be carried out without subjecting the device to voltage stress or sacrificing program data reliability. When setting the P or E bit in FLMCR1, the watchdog timer should be set beforehand as a precaution against program runaway, etc. (6) Do Not Set or Clear the SWE Bit During Program Execution in Flash Memory Clear the SWE bit before executing a program or reading data in flash memory. When the SWE bit is set, data in flash memory can be rewritten, but flash memory should only be accessed for verify operations (verification during programming/erasing). (7) Do Not Use Interrupts while Flash Memory is Being Programmed or Erased All interrupt requests, including NMI, should be disabled during FWE application to give priority to program/erase operations. (8) Do Not Perform Additional Programming. Erase the Memory before Reprogramming. In on-board programming, perform only one programming operation on a 32-byte programming unit block. In programmer mode, too, perform only one programming operation on a 128-byte programming unit block. Programming should be carried out with the entire programming unit block erased. (9) Before Programming, Check that the Chip is Correctly Mounted in the PROM Programmer. Overcurrent damage to the device can result if the index marks on the PROM programmer socket, socket adapter, and chip are not correctly aligned. (10)Do Not Touch the Socket Adapter or Chip During Programming. Touching either of these can cause contact faults and write errors.

Table 7.21 lists the registers that are present in the F-ZTAT version but not in the mask ROM version. If a register listed in table 7.21 is read in the mask ROM version, an undefined value will be returned. Therefore, if application software developed on the F-ZTAT version is switched to a mask ROM version product, it must be modified to ensure that the registers in table 7.21 have no effect.

The ROM is connected to the CPU by a 16-bit data bus. The CPU accesses both byte and word data in one state, enabling faster instruction fetches and higher processing speed. The flash memory versions of the H8S/2194C can be erased and programmed on-board as well as with a general-purpose PROM programmer. 8.1.1 Block Diagram Figure 8.1 shows a block diagram of the ROM.

Erasing is performed by block erase (in single-block units). When erasing all blocks, the individual blocks must be erased sequentially. Block erasing can be performed as required on 1-kbyte, 8-kbyte, 16-kbyte, 28kbyte, and 32-kbyte blocks. * Programming/erase times The flash memory programming time is 10 ms (typ.) for simultaneous 32-byte programming, equivalent to 300 s (typ.) per byte, and the erase time is 100 ms (typ.) per block. * Reprogramming capability The flash memory can be reprogrammed up to 100 times. * On-board programming modes There are two modes in which flash memory can be programmed/erased/verified on-board: -- Boot mode -- User program mode * Automatic bit rate adjustment If data transfer on boot mode, automatic adjustment is possible at host transfer bit rates and MCU's bit rates. * Protect modes There are three protect modes, hardware, software, and error protect, which allow protected status to be designated for flash memory program/erase/verify operations. * Programmer mode Flash memory can be programmed/erased in programmer mode, using a PROM programmer, as well as in on-board programming mode.

Flash memory initialization 4. Writing new application program The programming/erase control program in RAM is executed, and the flash memory is initialized (to H'FF).

There are two on-board programming modes: boot mode and user program mode. The pin settings for transition to each of these modes are shown in table 8.5. For a diagram of the transitions to the various flash memory modes, see figure 8.3.

In user program mode, the FWE pin should not be constantly set to 1. Set FWE to 1 to make a transition to user program mode before performing a program/erase/verify operation. 2. Can be used as I/O ports after boot mode is initiated. Rev. 2.0, 11/00, page 188 of 1037 8.4.1 Boot Mode When boot mode is used, the flash memory programming control program must be prepared in the host beforehand. The channel 1 SCI to be used is set to asynchronous mode. When a reset-start is executed after the MCU's pins have been set to boot mode, the boot program built into the MCU is started and the programming control program prepared in the host is serially transmitted to the MCU via the SCI1. In the MCU, the programming control program received via the SCI1 is written into the programming control program area in on-chip RAM. After the transfer is completed, control branches to the start address of the programming control program area and the programming control program execution state is entered (flash memory programming is performed). The transferred programming control program must therefore include coding that follows the programming algorithm given later. The system configuration in boot mode is shown in figure 8.7, and the boot program mode execution procedure in figure 8.8.

The SCI transmit/receive format should be set as follows: 8-bit data, 1 stop bit, no parity. The MCU calculates the bit rate of the transmission from the host from the measured low period, and transmits one H'00 byte to the host to indicate the end of bit rate adjustment. The host should confirm that this adjustment end indication (H'00) has been received normally, and transmit one H'55 byte to the MCU. If reception cannot be performed normally, initiate boot mode again (reset), and repeat the above operations. Depending on the host's transmission bit rate and the MCU's system clock frequency, there will be a discrepancy between the bit rates of the host and the MCU. To ensure correct SCI operation, the host's transfer bit rate should be set to (2400, 4800, or 9600) bps. Table 8.6 shows typical host transfer bit rates and system clock frequencies for which automatic adjustment of the MCU's bit rate is possible. The boot program should be executed within this system clock range.

The boot program area cannot be used until a transition is made to the execution state in boot mode for the programming control program transferred to RAM. H'FFE7B0 Boot program area* (3 kbytes) H'FFF3AF Programming control program area (2944 bytes) H'FFFF2F H'FFFFAF Reserved area (128 bytes) Note: * The boot program area cannot be used until a transition is made to the execution state for the programming control program transferred to RAM. Note that the boot program reamins stored in this area after a branch is made to the programming control program. Figure 8.10 RAM Areas in Boot Mode Rev. 2.0, 11/00, page 192 of 1037 (3) Notes on Use of Boot Mode: (a) When reset is released in boot mode, it measures the low period of the input at the SCI1's SI1 pin. The reset should end with SI1 pin high. After the reset ends, it takes about 100 states for the chip to get ready to measure the low period of the SI1 pin input. (b) In boot mode, if any data has been programmed into the flash memory (if all data is not 1), all flash memory blocks are erased. Boot mode is for use when user program mode is unavailable, such as the first time on-board programming is performed, or if the program activated in user program mode is accidentally erased. (c) Interrupts cannot be used while the flash memory is being programmed or erased. (d) The SI1 and SO1 pins should be pulled up on the board. (e) Before branching to the programming control program (RAM area H'FFF3B0), the chip terminates transmit and receive operations by the on-chip SCI (channel 1) (by clearing the RE and TE bits in SCR to 0), but the adjusted bit rate value remains set in BRR. The transmit data output pin, SO1, goes to the high-level output state (P21PCR = 1, P21PDR = 1). The contents of the CPU's internal general registers are undefined at this time, so these registers must be initialized immediately after branching to the programming control program. In particular, since the stack pointer (SP) is used implicitly in subroutine calls, etc., a stack area must be specified for use by the programming control program. The initial values of other on-chip registers are not changed. (f) Boot mode can be entered by making the pin settings shown in table 8.6 and executing a reset-start. When the chip detects the boot mode setting at reset release*1, it retains that state internally. Boot mode can be cleared by driving the reset pin low, waiting at least 20 states, then *1 setting the FWE pin and mode pins, and executing reset release . Boot mode can also be cleared by a WDT overflow reset. If the mode pin input levels are changed in boot mode, the boot mode state will be maintained in the microcomputer, and boot mode continued, unless a reset occurs. However, the FWE pin must not be driven low while the boot program is running or flash *2 memory is being programmed or erased . Notes: 1. Mode pin and FWE pin input must satisfy the mode programming setup time (tMDS = 4 states) with respect to the reset release timing. 2. For further information on FWE application and disconnection, see section 8.9, Flash Memory Programming and Erasing Precautions. Rev. 2.0, 11/00, page 193 of 1037 8.4.2 User Program Mode When set to user program mode, the chip can program and erase its flash memory by executing a user program/erase control program. Therefore, on-board reprogramming of the on-chip flash memory can be carried out by providing on-board means of FWE control and supply of programming data, and storing a program/erase control program in part of the program area as necessary. In this mode, the chip starts up in mode 1 and applies a high level to the FWE pin. The flash memory itself cannot be read while the SWE bit is set to 1 to perform programming or erasing, so the control program that performs programming and erasing should be run in on-chip RAM or external memory. Figure 8.11 shows the procedure for executing the program/erase control program when transferred to on-chip RAM. Write the FWE assessment program and transfer program (and the program/erase control program if necessary) beforehand MD0 = 1 Reset start Transfer program/erase control program to RAM Branch to program/erase control program in RAM area FWE = high * Execute program/erase control program (flash memory rewriting) Clear FWE * Branch to flash memory application program Note: Do not apply a constant high level to the FWE pin. Apply a high level to the FWE pin only when the flash memory is programmed or erased. Also, while a high level is applied to the FWE pin, the watchdog timer should be activated to prevent overprogramming or overerasing due to program runaway, etc. * For further information on FWE application and disconnection, see section 8.9, Flash Memory Programming and Erasing Precautions. Figure 8.11 User Program Mode Execution Procedure (Preliminary) Rev. 2.0, 11/00, page 194 of 1037 8.5 Programming/Erasing Flash Memory In the on-board programming modes, flash memory programming and erasing is performed by software, using the CPU. There are four flash memory operating modes: program mode, erase mode, program-verify mode, and erase-verify mode. For addresses H'00000 to H'1FFFF, transitions to these modes can be made by setting the PSU1, ESU1, P1, E1, PV1 and EV1 bits in FLMCR1 and for addresses H'20000 to H'3FFFF, transitions to these modes can be made by setting the PSU2, ESU2, P2, E2, PV2 and EV1 bits in FLMCR2. The flash memory cannot be read while being programmed or erased. Therefore, the program that controls flash memory programming/erasing (the programming control program) should be located and executed in on-chip RAM or external memory. Notes: 1. Operation is not guaranteed if setting/resetting of the SWE, ESU1, PSU1, EV1, PV1, E1, and P1 bits in FLMCR1, and the ESU2, PSU2, EV2, PV2, E2 and P2 bits in FLMCR2, is executed by a program in flash memory. 2. When programming or erasing, set FWE to 1 (programming/erasing will not be executed if FWE = 0). 3. Perform programming in the erased state. Do not perform additional programming on previously programmed addresses. Do not program addresses H'00000 to H'1FFFF and H'20000 to H'3FFFF at the same time. Operation is not guaranteed if both areas are programmed at the same time. 8.5.1 Program Mode (n = 1 for addresses H'0000 to H'1FFFF and n= 2 for addresses H'20000 to H'3FFFF) Follow the procedure shown in the program/program-verify flowchart in figure 8.12 to write data or programs to flash memory. Performing program operations according to this flowchart will enable data or programs to be written to flash memory without subjecting the device to voltage stress or sacrificing program data reliability. Programming should be carried out 32 bytes at a time. Table 29.9 in section 29.2.7, Flash Memory Characteristics, lists wait time (x, y, z, , , , and ) after setting or clearing each bit on the flash memory control registers 1 and 2 (FLMCR1 and FLMCR2) and the maximum write count (N). Following the elapse of (x) s or more after the SWE bit is set to 1 in flash memory control register 1 (FLMCR1), 32-byte program data is stored in the program data area and reprogram data area, and the 32-byte data in the reprogram data area written consecutively to the write addresses. The lower 8 bits of the first address written to must be H'00, H'20, H'40, H'60, H'80, H'A0, H'C0, or H'E0. Thirty-two consecutive byte data transfers are performed. The program address and program data are latched in the flash memory. A 32-byte data transfer must be performed even if writing fewer than 32 bytes; in this case, H'FF data must be written to the extra addresses. Next, the watchdog timer is set to prevent overprogramming in the event of program runaway, etc. Set more than (y + z + + ) s as the WDT overflow period. After this, preparation for Rev. 2.0, 11/00, page 195 of 1037 program mode (program setup) is carried out by setting the PSUn bit in FLMCRn, and after the elapse of (y) s or more, the operating mode is switched to program mode by setting the Pn bit in FLMCRn. The time during which the Pn bit is set is the flash memory programming time. Make a program setting so that the time for one programming operation is within the range of (z) s. 8.5.2 Program-Verify Mode (n =1 for addresses H'00000 to H'1FFFF and n = 2 for addresses H'20000 to H'3FFFF) In program-verify mode, the data written in program mode is read to check whether it has been correctly written in the flash memory. After the elapse of a given programming time, the programming mode is exited (the Pn bit in FLMCRn is cleared, then the PSUn bit in FLMCRn is cleared at least () s later). The watchdog timer is cleared after the elapse of () s or more, and the operating mode is switched to program-verify mode by setting the PVn bit in FLMCRn. Before reading in program-verify mode, a dummy write of H'FF data should be made to the addresses to be read. The dummy write should be executed after the elapse of () s or more. When the flash memory is read in this state (verify data is read in 16-bit units), the data at the latched address is read. Wait at least () s after the dummy write before performing this read operation. Next, the originally written data is compared with the verify data, and reprogram data is computed (see figure 8.12) and transferred to the reprogram data area. After 32 bytes of data have been verified, exit programverify mode, wait for at least () s, then clear the SWE bit in FLMCR1. If reprogramming is necessary, set program mode again, and repeat the program/program-verify sequence as before. However, ensure that the program/program-verify sequence is not repeated more than (N) times on the same bits. Rev. 2.0, 11/00, page 196 of 1037 START Set SWE bit in FLMCR1 Wait (x) s Programming must be excuted in the erased state.

The lower 8 bits of the first address written to must be H'00, H'20, H'40, H'60, H'80, H'A0, H'C0,, or H'E0. A 32-byte data transfer must be performed even if writing fewer than 32 bytes; in this case, H'FF data must be written to the extra addresses. 2. Verify data is read in 16-bit (word) units. 3. Even in case of the bit which is already-programmed in the 32-byte programming loop, perform additional programming if the bit fails at the next verify. 4. An area for storing program data (32 bytes) and reprogram data (32 bytes) must be provided in RAM. The contents of the latter are rewritten as programming progresses. 5. The values of x, y, z, , , , , and N are listed in section 29.2.7, Flash Memory Characteristics.

Table 28.9 in section 28.2.7, Flash Memory Characteristics lists wait time (x, y, z, , , , and ) after setting or clearing each bit on the flash memory control registers 1 and 2 (FLMCR1 and FLMCR2) and the maximum clearing count (N). To perform data or program erasure, make a 1 bit setting for the flash memory area to be erased in erase block register 1 or 2 (EBR1 or EBR2) at least (x) s after setting the SWE bit to 1 in flash memory control register 1 (FLMCR1). Next, the watchdog timer is set to prevent overerasing in the event of program runaway, etc. Set more than (y + z + + ) ms as the WDT overflow period. After this, preparation for erase mode (erase setup) is carried out by setting the ESUn bit in FLMCRn, and after the elapse of (y) s or more, the operating mode is switched to erase mode by setting the En bit in FLMCR1. The time during which the En bit is set is the flash memory erase time. Ensure that the erase time does not exceed (z) ms. Note: With flash memory erasing, preprogramming (setting all data in the memory to be erased to 0) is not necessary before starting the erase procedure. 8.5.4 Erase-Verify Mode (n = 1 for addresses H'00000 to H'1FFFF and n = 2 for address H'20000 to H'3FFFF) In erase-verify mode, data is read after memory has been erased to check whether it has been correctly erased. After the elapse of the erase time, erase mode is exited (the En bit in FLMCRn is cleared, then the ESU bit in FLMCR2 is cleared at least () s later), the watchdog timer is cleared after the elapse of () s or more, and the operating mode is switched to erase-verify mode by setting the EVn bit in FLMCRn. Before reading in erase-verify mode, a dummy write of H'FF data should be made to the addresses to be read. The dummy write should be executed after the elapse of () s or more. When the flash memory is read in this state (verify data is read in 16-bit units), the data at the latched address is read. Wait at least () s after the dummy write before performing this read operation. If the read data has been erased (all 1), a dummy write is performed to the next address, and erase-verify is performed. If the read data has not been erased, set erase mode again, and repeat the erase/erase-verify sequence in the same way. However, ensure that the erase/erase-verify sequence is not repeated more than (N) times. When verification is completed, exit erase-verify mode, and wait for at least () s. If erasure has been completed on all the erase blocks, clear the SWE bit in FLMCR1. If there are any unerased blocks, make a 1 bit setting in EBR1 or EBR2 for the flash memory area to be erased, and repeat the erase/eraseverify sequence in the same way.

The values of x, y, z, , , , , and N are listed in section 29.2.7, Flash Memory Characteristics. Verify data is read in 16-bit (word) units. Set only one bit in EBR1 or EBR2. More than one bit cannot be set. Erasing is performed in block units. To erase a number of blocks, the individual blocks must be erased sequentially. Figure 8.13 Erase/Erase-Verify Flowchart (Single-Block Erase) Rev. 2.0, 11/00, page 199 of 1037 8.6 Flash Memory Protection There are three kinds of flash memory program/erase protection: hardware protection, software protection, and error protection. 8.6.1 Hardware Protection Hardware protection refers to a state in which programming/erasing of flash memory is forcibly disabled or aborted. Hardware protection is reset by settings in flash memory control registers 1 and 2 (FLMCR1, FLMCR2) and erase block registers 1 and 2 (EBR1, EBR2). (See table 8.7.) Table 8.7 Hardware Protection Functions Item FWE pin protection Reset/standby protection Description * When a low level is input to the FWE pin, FLMCR1, FLMCR2, EBR1, and EBR2 are initialized, and the program/erase-protected state is entered * In a reset (including a WDT overflow reset) and in power-down state (excluding the medium-speed mode, module stop mode, and sleep mode), FLMCR1, FLMCR2 (excluding the FLER bit), EBR1, and EBR2 are initialized, and the program/eraseprotected state is entered * In a reset via the 5(6 pin, the reset state is not entered unless the 5(6 pin is held low until oscillation stabilizes after powering on. In the case of a reset during operation, hold the 5(6 pin low for the 5(6 pulse width specified in the AC characteristics section Program Yes Erase Yes Yes Yes Rev. 2.0, 11/00, page 200 of 1037 8.6.2 Software Protection Software protection can be implemented by setting the SWE bit in FLMCR1 and erase block registers 1 and 2 (EBR1, EBR2). When software protection is in effect, setting the P1 or E1 bit in flash memory control register 1 (FLMCR1), or setting the P2 or E2 bit in flash memory control register 2 (FLMCR2) does not cause a transition to program mode or erase mode. (See table 8.8.) Table 8.8 Software Protection Functions Item SWE bit protection Block specification protection Description * Clearing the SWE bit to 0 in FLMCR1 sets the program/erase-protected state for all blocks (Execute in on-chip RAM or external memory) * Erase protection can be set for individual blocks by settings in erase block registers 1 and 2 (EBR1, EBR2) * Setting EBR1 and EBR2 to H'00 places all blocks in the erase-protected state Program Yes Erase Yes - Yes Rev. 2.0, 11/00, page 201 of 1037 8.6.3 Error Protection In error protection, an error is detected when MCU runaway occurs during flash memory programming/erasing, or operation is not performed in accordance with the program/erase algorithm, and the program/erase operation is aborted. Aborting the program/erase operation prevents damage to the flash memory due to overprogramming or overerasing. If the MCU malfunctions during flash memory programming/erasing, the FLER bit is set to 1 in FLMCR2 and the error protection state is entered. The FLMCR1, FLMCR2, EBR1, and EBR2 settings are retained, but program mode or erase mode is aborted at the point at which the error occurred. Program mode or erase mode cannot be re-entered by re-setting the P1, E1, P2 or E2 bit. However, PV1, EV1, PV2 or EV2 bit setting is enabled, and a transition can be made to verify mode. FLER bit setting conditions are as follows: (1) When flash memory is read during programming/erasing (including a vector read or instruction fetch) (2) Immediately after exception handling (excluding a reset) during programming/erasing (3) When a SLEEP instruction is executed during programming/erasing Error protection is released only by a reset and in hardware standby mode. Figure 8.14 shows the flash memory state transition diagram.

There are three reasons for this: (1) Interrupt during programming or erasing might cause a violation of the programming or erasing algorithm, with the result that normal operation could not be assured. (2) In the interrupt exception handling sequence during programming or erasing, the vector *2 would not be read correctly , possibly resulting in MCU runaway. (3) If interrupt occurred during boot program execution, it would not be possible to execute the normal boot mode sequence. For these reasons, in on-board programming mode alone there are conditions for disabling interrupt, as an exception to the general rule. However, this provision does not guarantee normal erasing and programming or MCU operation. All requests, including NMI input, must therefore be disabled inside and outside the MCU during FWE application. Interrupt is also disabled in the error-protection state while the Pn or En bit remains set in FLMCRn. Notes: 1. Interrupt requests must be disabled inside and outside the MCU until data write by the write control program is complete. 2. The vector may not be read correctly in this case for the following two reasons: * If flash memory is read while being programmed or erased (while the Pn or En bit is set in FLMCRn), correct read data will not be obtained (undetermined values will be returned). * If the interrupt entry in the interrupt vector table has not been programmed yet, interrupt exception handling will not be executed correctly. Rev. 2.0, 11/00, page 203 of 1037 8.8 8.8.1 Flash Memory Programmer Mode Programmer Mode Setting Programs and data can be written and erased in programmer mode as well as in the on-board programming modes. In programmer mode, the on-chip ROM can be freely programmed using a PROM programmer that supports Hitachi microcomputer device type with 128-kbyte on-chip flash memory. Flash memory read mode, auto-program mode, auto-erase mode, and status read mode are supported with these device types. In auto-program mode, auto-erase mode, and status read mode, a status polling procedure is used, and in status read mode, detailed internal signals are output after execution of an auto-program or auto-erase operation. 8.8.2 Socket Adapters and Memory Map In programmer mode, a socket adapter is mounted on the writer programmer. The socket adapter product codes are listed in table 8.9. Figure 8.15 shows the memory map in programmer mode.

Details of each mode are given below. (1) Memory Read Mode Memory read mode supports byte reads. (2) Auto-Program Mode Auto-program mode supports programming of 128 bytes at a time. Status polling is used to confirm the end of auto-programming. (3) Auto-Erase Mode Auto-erase mode supports automatic erasing of the entire flash memory. Status polling is used to confirm the end of auto-erasing. (4) Status Read Mode Status polling is used for auto-programming and auto-erasing, and normal termination can be confirmed by reading the FO6 signal. In status read mode, error information is output if an error occurs.

To read memory contents, a transition must be made to memory read mode by means of a command write before the read is executed.

Figure 8.23 Oscillation Stabilization Time, Boot Program Transfer Time, and Power Supply Fall Sequence 8.8.10 Notes On Memory Programming (1) When programming addresses which have previously been programmed, carry out autoerasing before auto-programming. (2) When performing programming using programmer mode on a chip that has been programmed/erased in an on-board programming mode, auto-erasing is recommended before carrying out auto-programming. Notes: 1. The flash memory is initially in the erased state when the device is shipped by Hitachi. For other chips for which the erasure history is unknown, it is recommended that auto-erasing be executed to check and supplement the initialization (erase) level. 2. Auto-programming should be performed once only on the same address block. Rev. 2.0, 11/00, page 216 of 1037 8.9 Flash Memory Programming and Erasing Precautions Precautions concerning the use of on-board programming mode and programmer mode are summarized below. (1) Use the Specified Voltages and Timing for Programming and Erasing Applied voltages in excess of the rating can permanently damage the device. Use a PROM programmer that supports Hitachi microcomputer device type with 256-kbyte on-chip flash memory. Do not select the HN28F101 setting for the PROM programmer, and only use the specified socket adapter. Incorrect use will result in damaging the device. (2) Powering On and Off Do not apply a high level to the FWE pin until VCC has stabilized. Also, drive the FWE pin low before turning off VCC. When applying or disconnecting VCC, fix the FWE pin low and place the flash memory in the hardware protection state. The power-on and power-off timing requirements should also be satisfied in the event of a power failure and subsequent recovery. (3) FWE Application/Disconnection FWE application should be carried out when MCU operation is in a stable condition. If MCU operation is not stable, fix the FWE pin low and set the protection state. The following points must be observed concerning FWE application and disconnection to prevent unintentional programming or erasing of flash memory: (a) Apply FWE when the VCC voltage has stabilized within its rated voltage range. (b) In boot mode, apply and disconnect FWE during a reset. (c) In user program mode, FWE can be switched between high and low level regardless of the reset state. FWE input can also be switched during program execution in flash memory. (d) Do not apply FWE if program runaway has occurred. (e) Disconnect FWE only when the SWE, ESU1, ESU2, PSU1, PSU2, EV1, EV2, PV1, PV2, P1, P2, E1 and E2 bits in FLMCR1 and FLMCR2 are cleared. Make sure that the SWE, ESU1, ESU2, PSU1, PSU2, EV1, EV2, PV1, PV2, P1, P2, E1 and E2 bits are not set by mistake when applying or disconnecting FWE. (4) Do Not Apply a Constant High Level to the FWE Pin Apply a high level to the FWE pin only when programming or erasing flash memory. A system configuration in which a high level is constantly applied to the FWE should be avoided. Also, while a high level is applied to the FWE pin, the watchdog timer should be activated to prevent overprogramming or overerasing due to program runaway, etc. Rev. 2.0, 11/00, page 217 of 1037 (5) Use the Recommended Algorithm when Programming and Erasing Flash Memory The recommended algorithm enables programming and erasing to be carried out without subjecting the device to voltage stress or sacrificing program data reliability. When setting the Pn or En bit in FLMCR1 and FLMCR2, the watchdog timer should be set beforehand as a precaution against program runaway, etc. (6) Do Not Set or Clear the SWE Bit During Program Execution in Flash Memory Clear the SWE bit before executing a program or reading data in flash memory. When the SWE bit is set, data in flash memory can be rewritten, but flash memory should only be accessed for verify operations (verification during programming/erasing). (7) Do Not Use Interrupts while Flash Memory is Being Programmed or Erased All interrupt requests, including NMI, should be disabled during FWE application to give priority to program/erase operations. (8) Do Not Perform Additional Programming. Erase the Memory before Reprogramming. In on-board programming, perform only one programming operation on a 32-byte programming unit block. In programmer mode, too, perform only one programming operation on a 128-byte programming unit block. Programming should be carried out with the entire programming unit block erased. (9) Before Programming, Check that the Chip is Correctly Mounted in the PROM Programmer. Overcurrent damage to the device can result if the index marks on the PROM programmer socket, socket adapter, and chip are not correctly aligned. (10)Do Not Touch the Socket Adapter or Chip During Programming. Touching either of these can cause contact faults and write errors. Rev. 2.0, 11/00, page 218 of 1037 8.10 Note on Switching from F-ZTAT Version to Mask ROM Version The mask ROM version does not have the internal registers for flash memory control that are provided in the F-ZTAT version. Table 8.21 lists the registers that are present in the F-ZTAT version but not in the mask ROM version. If a register listed in table 8.21 is read in the mask ROM version, an undefined value will be returned. Therefore, if application software developed on the F-ZTAT version is switched to a mask ROM version product, it must be modified to ensure that the registers in table 8.21 have no effect.

The oscillator and duty adjustment circuit have a function for adjusting the waveform of the external clock input at the OSC1 pin. When the prescribed clock signal is input at the OSC1 pin, internal clock signal output is fixed after the elapse of the external clock output settling delay time (tDEXT). As the clock signal output is not fixed during the tDEXT period, the reset signal should be driven low to maintain the reset state.

The clock is not sampled in subactive mode, subsleep mode, or watch mode. 10.9 Notes on the Resonator Resonator characteristics are closely related to the user board design. Perform appropriate assessment of resonator connection, mask version and F-ZTAT, by referring to the connection example given in this section. The resonator circuit rate differs depending on the free capacity of the resonator and the execution circuit, so consult with the resonator manufacturer before determination. Make sure the voltage applied to the resonator pin does not exceed the maximum rated voltage. Rev. 2.0, 11/00, page 234 of 1037 Section 11 I/O Port 11.1 11.1.1 Overview Port Functions This LSI has seven 8-bit I/O ports (including one CMOS high-current port), one 4-bit I/O port, and one 8-bit input port. Table 11.1 shows the functions of each port. Each I/O part a port control register (PCR) that controls an input and output and a port data register (PDR) for storing output data. The input and output can be controlled in a unit of bit. The pin whose peripheral function is used both as an alternative function can set the pin function in a unit of bit by a port mode register (PMR). 11.1.2 Port Input (1) Reading a Port * When a general port of PCR = 0 (input) is read, the pin level is read. * When a general port of PCR = 1 (output) is read, the value of the corresponding PDR bit is read. * When the pins (excluding AN7 to AN0 and RP7 to RP0 pins) set to the peripheral function are read, the results are as given in items (1) and (2) according to the PCR value. (2) Processing Input Pins The general input port or general I/O port is gated by read signals. Unused pins can be left open if they are not read. However, if an open pin is read, a feedthrough current may apply during the read period according to an intermediate level. The read period is about one-state. Relevant ports: P0, P1, P2, P3, P4, P5, P6, P7, P8 When an alternative pin is set to an alternative function other than the general I/O, always set the pin level to a high or low level. If the pin is left open, a feedthrough current applies according to an intermediate level, which adversely affects reliability, causes malfunctions, and in the worst case may damage the pin. Because the PMR is not initialized in low power consumption mode, pay attention to the pin input level after the mode has been shifted to the low power consumption mode.

Settings in PUR1 to PUR3 are valid when the pin function is set to an input by PCR1 to PCR3. If the pin function is set to an output, the MOS pull-up transistor is turned off. Figure 11.1 shows the circuit configuration of a pin with a MOS pull-up transistor. When the pin whose peripheral function is used both as an alternative function is set to the alternative output function, the MOS pull-up transistor is turned off. When the pin is set to the alternative input function, the MOS pull-up transistor is controlled according to the PUR setting regardless of PCR.

Port 1 consists of pins that are used both as standard I/O ports (P17 to P10) and frequency division clock output (TMOW), input capture input (,&), or external interrupt request inputs (,54 to ,54). It is switched by port mode register 1 (PMR1) and port control register 1 (PCR1). Port 1 can select the functions of MOS pull-up transistors.

The switching is specified in a unit of bit. PMR1 is an 8-bit read/write enable register. When reset, PMR1 is initialized to H'00. Note the following items when the pin functions are switched by PMR1. (1) If port 1 is set to an ,& input pin and ,54 to ,54 by PMR1, the pin level needs be set to the high or low level regardless of the active mode and low power consumption mode. The pin level must not be set to an intermediate level. (2) When the pin functions of P16/,& and P15/,54 to P10/,54 are switched by PMR1, they are incorrectly recognized as edge detection according to the state of a pin signal and a detection signal may be generated. To prevent this, perform the operation in the following procedure. (a) Before switching the pin functions, inhibit an interrupt enable flag from being interrupted. (b) After having switched the pin functions, clear the relevant interrupt request flag to 0 by a single instruction.

The switchings of the P46/FTOB and P45/FTOA functions are controlled by TOCR. See section 17, Timer X1. The FTIA, FTIB, FTIC, and FTID inputs always function.

Port 6 functions as a realtime output port when PMR6 = 1 and as a general I/O port when PMR6 = 0. The operation per port 6 function is shown below. (See figure 11.2.)

When a trigger is input, PMR6 transfers the PDR6 data to PDRS6 and the PCR6 data to PCRS6, respectively. In this case, when PCRS6 is 1, the PDRS6 data of the corresponding bit is output to the RP pin. When PCRS6 is 0, the RP pin of the corresponding bit is output to the high-impedance state. In other words, the pin output state (High or Low) or high-impedance state can instantaneously be switched by a trigger input. Adversely, when PDR6 is read, the PDR6 values are read regardless of the PCR6 and PCRS6 values. (2) Operation of the general I/O port (PMR6 = 0) When PMR6 is 0, it operates as a general I/O port. When data is written to PDR6, the same data is also written to PDRS6. Accordingly, because both PDR6 and PDRS6 and both PCR6 and PCRS6 can be handled as one register, respectively, they can be used in the same way as a normal general I/O port. In other words, if PCR6 is 1, the PDR6 data of the corresponding bit is output to the P6 pin. If PCR6 is 0, the P6 pin of the corresponding bit becomes an input. Adversely, assuming that PDR6 is read, the PDR6 values are read when PCR6 is 1 and the pin values are read when PCR6 is 0. 11.8.5 Pin States Table 11.22 shows the port 6 pin states in each operation mode.

MSTPCRH Bit 7 MSTP15 0 1 Description Cancels the module stop mode of the Timer A Sets the module stop mode of the Timer A (Initial value) Rev. 2.0, 11/00, page 293 of 1037 12.3 Operation The Timer A is an 8-bit timer for use as an interval timer and as a clock time base connecting to a 32.768 kHz crystal oscillator. 12.3.1 Operation as the Interval Timer When the TMA3 bit of the TMA is cleared to 0, the Timer A works as an 8-bit interval timer. When resetince the TCA is cleared to H'00 and as the TMA3 bit is cleared to 0, the Timer A continues counting up as the interval counter without interrupts right after resetting. As the operation clock for the Timer A, selection can be made from eight different types of internal clocks being output from the PSS by the TMA2 to TMA0 bits of the TMA. When the clock signal is input after the reading of the TCA reaches H'FF, the Timer A overflows and the TMAOV bit of the TMA will be set to 1. At this time, when the TMAIE bit of the TMA is 1, interrupt occurs. When overflowing occurs, the reading of the TCA returns to H'00 before resuming counting up. Consequently, it works as the interval timer to produce overflow outputs periodically at every 256 input clocks. 12.3.2 Operation of the Timer for Clocks When the TMA3 bit of the TMA is set to 1, the Timer A works as a time base for the clock. As the overflow cycles for the Timer A, selection can be made from four different types by counting the clock being output from the PSW by the TMA1 bit and TMA0 bit of the TMA. 12.3.3 Initializing the Counts When the TMA3 and TMA2 bits are set to 11, the PSW and TCA will be cleared to H'00 to come to a stop. At this state, writing 10 to the TMA3 bit and TMA2 bit makes the Timer A to start counting from H'00 under the time base mode for clocks. After clearing the PSW and TCA using the TMA3 and TMA2 bits, writing 00 or 01 to the TMA3 bit and TMA2 bit work to make the Timer A to start counting from H'00 under the interval timer mode. However, since the PSS is not cleared, the period to the first count is not constant. Rev. 2.0, 11/00, page 294 of 1037 Section 13 Timer B 13.1 Overview The Timer B is an 8-bit up-counter. The Timer B is equipped with two different types of functions namely, the interval function and the auto reloading function. 13.1.1 Features * Selection from choices of seven different types of internal clocks (/16384, /4096, /1024, /512, /128, /32 and /8) or selection of external clock are possible. * When the counter overflows, a interrupt request will be issued. 13.1.2 Block Diagram Figure 13.1 shows a block diagram of the Timer B.

The TMB is an 8-bit read/write register which works to control the interrupts, to select the auto reloading function and to select the input clock. When reset, the TMB is initialized to H'18.

See section 13.2.4, Port Mode Register 5 (PMR5).

The input clock can be selected by the TMB12 to TMB10 of the TMB. When the TCB overflows (H'FF H'00 or H'FF TLB setting), a interrupt request of the Timer B will be issued. When reset, the TCB is initialized to H'00. 13.2.3 Timer Load Register B (TLB) Bit : 7 TLB17 Initial value : R/W : 0 W 6 TLB16 0 W 5 TLB15 0 W 4 TLB14 0 W 3 TLB13 0 W 2 TLB12 0 W 1 TLB11 0 W 0 TLB10 0 W The TLB is an 8-bit write only register which works to set the reloading value of the TCB. When the reloading value is set to the TLB, the value will be simultaneously loaded to the TCB and the TCB starts counting up from the set value. Also, during an auto reloading operation, when the TCB overflows, the value of the TLB will be loaded to the TCB. Consequently, the overflowing cycle can be set within the range of 1 to 256 input clocks. When reset, the TLB is initialized to H'00. Rev. 2.0, 11/00, page 299 of 1037 13.2.4 Port Mode Register 5 (PMR5) Bit : 7 -- 6 -- 1 -- 5 -- 1 -- 4 -- 1 -- 3 PMR53 0 R/W 2 PMR52 0 R/W 1 PMR51 0 R/W 0 -- 1 -- Initial value : R/W : 1 -- The port mode register 5 (PMR5) works to changeover the pin functions of the port 5 and to designate the edge sense of the event inputs of the Timer B (TMBI). The PMR5 is an 8-bit read/write register. When reset, the PMR5 will be initialized to H'F1. See section 11.7, Port 5 for other information than bit 1. Bit 1: Selecting the Edges of the Event Inputs to the Timer B (PMR51) This bit works to select the input edge sense of the TMBI pins. Bit 1 PMR51 0 1 Description Detects the falling edge of the event inputs to the Timer B Detects the rising edge of the event inputs to the Timer B (Initial value) 13.2.5 Module Stop Control Register (MSTPCR) MSTPCRH Bit : 7 1 6 1 5 1 4 1 3 1 2 1 1 1 0 1 7 1 6 1 5 1 MSTPCRL 4 1 3 1 2 1 1 1 0 1 MSTP15 MSTP14 MSTP13 MSTP12 MSTP11 MSTP10 MSTP9 MSTP8 MSTP7 MSTP6 MSTP5 MSTP4 MSTP3 MSTP2 MSTP1 MSTP0 Initial value : R/W : R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W The MSTPCR are 8-bit read/write twin registers which work to control the module stop mode. When the MSTP14 bit is set to 1, the Timer B stops its operation at the ending point of the bus cycle to shift to the module stop mode. For more information, see section 4.5, Module stop mode. When reset, the MSTPCR is initialized to H'FFFF. Rev. 2.0, 11/00, page 300 of 1037 Bit 6: Module Stop (MSTP14) This bit works to designate the module stop mode for the Timer B. MSTPCRH Bit 6 MSTP14 0 1 Description Cancels the module stop mode of the Timer B Sets the module stop mode of the Timer B (Initial value) Rev. 2.0, 11/00, page 301 of 1037 13.3 13.3.1 Operation Operation as the Interval Timer When the TMB17 bit of the TMB is set to 0, the Timer B works as an 8-bit interval timer. When reset, since the TCB is cleared to H'00 and as the TMB17 bit is cleared to 0, the Timer B continues counting up as the interval timer without interrupts right after resetting. As the clock source for the Timer B, selection can be made from seven different types of internal clocks being output from the prescaler unit by the TMB12 to TMB10 bits of the TMB or an external clock through the TMBI input pin can be chosen instead. When the clock signal is input after the reading of the TCB reaches H'FF, the Timer B overflows and the TMBIF bit of the TMB will be set to 1. At this time, when the TMBIE bit of the TMB is 1, interrupt occurs. When overflowing occurs, the reading of the TCB returns to H'00 before resuming counting up. When a value is set to the TLB while the interval timer is in operation, the value which has been set to the TLB will be loaded to the TCB simultaneously. 13.3.2 Operation as the Auto Reload Timer When the TMB17 of the TMB is set to 1, the Timer B works as an 8-bit auto reload timer. When a reload value is set in the TLB, the value is loaded onto the TCB at the same time, and the TCB starts counting up from the value. When the clock signal is input after the reading of the TCB reaches H'FF, the Timer B overflows and the TLB value is loaded onto the TCB, then the TCB continues counting up from the loaded value. Accordingly, overflow interval can be set within the range of 1 to 256 clocks depending on the TLB value. Clock source and interrupts in the auto reload operation are the same as those in the interval operation. When the TLB value is re-set while the auto reload timer is in operation, the value which has been set to the TLB will be loaded onto the TCB simultaneously. 13.3.3 Event Counter The Timer B works as an event counter using the TMBI pin as the event input pin. When the TMB12 to TMB10 are set to 111, the external event will be selected as the clock source and the TCB counts up at the leading edge or the trailing edge of the TMBI pin inputs. Rev. 2.0, 11/00, page 302 of 1037 Section 14 Timer J 14.1 Overview The Timer J consists of twin 8-bit counters. It carries seven different operation modes such as reloading and event counting. 14.1.1 Features The Timer J consists of twin 8-bit reloading timers and it is usable under the various functions as follows: (a) Twin 8-bit reloading timers (Among the two, one is capable to make timer outputs) (b) Twin 8-bit event counters (Capable to make reloading) (c) 8-bit event counter (Capable to make reloading) + 8-bit reload timer (d) 16-bit event counter (Capable to make 16-bit reloading) (e) 16-bit reload timer (Capable to make 16-bit reloading) (f) Remote controlled transmissions (g) "Take up/Supply reel pulse" dividing (8 bit x 2 units) 14.1.2 Block Diagram Figure 14.1 is a block diagram of the Timer J.

The TMJ is an 8-bit register and Bit-1 is for read only and all the remaining bits are applicable to read/write. When reset, the TMJ is initialized to H'00. Under all other modes than the remote controlling mode, writing into the TMJ works to initialize the counters (TCJ and TCK) to H'FF. Bits 7 and 6: Selecting the Inputting Clock to the TMJ-1 (PS11 and PS10) These bits work to select the clock to input to the TMJ-1.

(When IRQ1 falling, select IRQ2 rising and when IRQ1 rising, select IRQ2 falling) Rev. 2.0, 11/00, page 306 of 1037 Bit 5: Starting the Remote Controlled Operation (ST) This bit works to start the remote controlled operations. When this bit is set to 1, clock signal is supplied to the TMJ-1 to start signal transmissions. When this bit is cleared to 0, clock supply stops to discontinue the operation. The ST bit will be valid under the remote controlling mode, namely, when the Bit 0 (T/R bit) is 1 and the Bit 4 (8/16 bit) is 0. Under other modes than the remote controlling mode, it will be fixed to 0. When a shift to the low power consumption mode is made during remote controlled operation, the ST bit will be cleared to 0.

Description 8-bit timer x 2 Remote controlling mode 16-bit timer (Initial value) When writing is made into the TMJ under the timer mode, the counters (TCJ and TCK) will be initialized (H'FF). Consequently, writing into the reloading registers (TLJ an TLK) should be conducted after finishing settings with the TMJ. Under the remote controlling mode, although the TLJ and the TLK will not be initialized even when writing is made into the TMJ, follow the sequence listed below when starting a remote controlling operation. (1) Make setting to the remote controlling mode with the TMJ. (2) Write the data into the TLJ and TLK. (3) Start the remote controlled operation by use of the TMJ. (ST bit = 1) Even under 16-bit operations, TMJ1I interrupt requests from the TMJ-1 will be valid.

These settings are valid only when the BUZZ1 and BUZZ0 bits are being set to 1 and 0. When PB-CTL or REC-CTL is chosen, signal duties will be output as they are. In case of DVCTL signals, signals from the CTL dividing circuit will be toggled before being output. Signal waveforms divided by the CTL dividing circuit into "n-divisions" will further be divided into halves. (Namely, "2n" divisions, 50% duty waveform).

The inputting clock can be selected by the PS11 and PS10 bits of the TMJ. TCJ values can be readout always. Nonetheless, when the 8/16 bit of the TMJ is being set to 1 (means when setting is made to 16-bit operation), reading is possible under the word command only. At this time, the TCK of the TMJ-2 can be read by the upper 8 bits and the TCJ can be read by the lower 8 bits. When the TCJ underflows (H'00 Reloading value), regardless of the operation mode setting of the 8/16 bit, the TMJ1I bit of the TMJS will be set to 1. The TCJ and TLJ are being allocated to the same address.

The inputting clock can be selected by the PS21 and PS20 bits of the TMJ. TCK values can be readout always. Nonetheless, when the 8/16 bit of the TMJ is being set to 1 (means when setting is made to 16-bit operation), reading is possible under the word command only. At this time, the TCK can be read by the upper 8 bits and the TCJ of the TMJ-1 can be read by the lower 8 bits. When the TCK underflows (H'00 Reloading value), the TMJ2I bit of the TMJS will be set to 1. The TCK and TLK are being allocated to the same address. When reset, the TCK is initialized to H'FF.

When the reloading value is set to the TLJ, the value will be simultaneously loaded to the TCJ and the TCJ starts counting down from the set value. Also, during an auto reloading operation, when the TCJ underflows, the value of the TLJ will be loaded to the TCJ. Consequently, the underflowing cycle can be set within the range of 1 to 256 input clocks. Nonetheless, when the 8/16 bit of the TMJ is being set to 1 (means when setting is made to 16-bit operation), writing is possible under the word command only. At this time, the upper 8 bits can be written into the TLK of the TMJ-2 and the lower 8 bits can be written into the TLJ. The TLJ and TCJ are being allocated to the same address. When reset, the TLJ is initialized to H'FF. 14.2.7 Timer Load Register K (TLK) Bit : 7 TLR27 Initial value : R/W : 1 W 6 TLR26 1 W 5 TLR25 1 W 4 TLR24 1 W 3 TLR23 1 W 2 TLR22 1 W 1 TLR21 1 W 0 TLR20 1 W The timer load register K (TLK) is an 8-bit write only register which works to set the reloading value of the TCK. When the reloading value is set to the TLK, the value will be simultaneously loaded to the TCK and the TCK starts counting down from the set value. Also, during an auto reloading operation, when the TCK underflows, the value of the TLK will be loaded to the TCK. Consequently, the underflowing cycle can be set within the range of 1 to 256 input clocks. Nonetheless, when the 8/16 bit of the TMJ is being set to 1 (means when setting is made to 16-bit operation), writing is possible under the word command only. At this time, the upper 8 bits can be written into the TLK and the lower 8 bits can be written into the TLJ of the TMJ-1. The TLK and TCK are being allocated to the same address. When reset, the TLK is initialized to H'FF.

When the MSTP13 bit is set to 1, the Timer J stops its operation at the ending point of the bus cycle to shift to the module stop mode. For more information, see section 4.5, Module Stop Mode. When reset, the MSTPCR is initialized to H'FFFF. Bit 5: Module Stop (MSTP13) This bit works to designate the module stop mode for the Timer J. MSTPCRH Bit 5 MSTP13 0 1 Description Cancels the module stop mode of the Timer J Sets the module stop mode of the Timer J (Initial value) Rev. 2.0, 11/00, page 315 of 1037 14.3 14.3.1 Operation 8-bit Reload Timer (TMJ-1) The TMJ-1 is an 8-bit reload timer. As the clock source, dividing clock or edge signals through the ,54 pin are being used. By selecting the edge signals through the ,54 pin, it can also be used as an event counter. While it is working as an event counter, its reloading function is workable simultaneously. When data are written into the reloading register TLJ, these data will be written into the counter TCJ simultaneously. Also, when the counter TCJ underflows, the data of the reloading register TLJ will be reloaded to the counter TCJ. When the counter underflows, TMJ1I interrupt requests will be issued. The underflow will be toggled and, by a appropriate selection of the dividing clock, buzzer outputs will be issued or carrier frequencies for remote controlling transmissions can be acquired. The TMJ-1 and TMJ-2, in combination, can be used as a 16-bit reload timer. Nonetheless, when they are being used, in combination, as a 16-bit timer, word command only is valid and the TCK works as the down counter for the upper 8 bits and the TCJ works as the down counter for the lower 8 bits, means a reloading register of total 16 bits. When data are written into a 16-bit reloading register, the same data will be written into the 16bit counter. Also, when the 16-bit counter underflows, the data of the 16-bit reloading register will be reloaded into the counter. Even when they are making a 16-bit operation, the TMJ1I interrupt requests of the TMJ-1 and BUZZ outputs are effective. In case these functions are not necessary, make them invalid by programming. The TMJ-1 and TMJ-2, in combination, can be used for remote controlled data transmission. Regarding the remote controlled data transmission, see section 14.3.3, Remote Controlled Data Transmission. 14.3.2 8-bit Reload Timer (TMJ-2) The TMJ-2 is an 8-bit down-counting reload timer. As the clock source, dividing clock, edge signals through the ,54 pin or the underflow signals from the TMJ-1 are being used. By selecting the edge signals through the ,54 pin, it can also be used as an event counter. While it is working as an event counter, its reloading function is workable simultaneously. When data are written into the reloading register TLK, these data will be written into the counter TCK simultaneously. Also, when the counter TCK underflows, the data of the reloading register TLK will be made to the data counter TCK. When the counter underflows, TMJ2I interrupt requests will be issued. The TMJ-2 and TMJ-1, in combination, can be used as a 16-bit reload timer. For more information on the 16-bit reload timer, see section 14.3.1, 8-bit Reload Timer (TMJ-1). The TMJ-2 and TMJ-1, in combination, can be operated by remote controlled data transmission. Rev. 2.0, 11/00, page 316 of 1037 Regarding the remote controlled data transmission, see section 14.3.3, Remote Controlled Data Transmission. 14.3.3 Remote Controlled Data Transmission The Timer J is capable of making remote controlled data transmission. The carrier frequencies for the remote controlled data transmission can be generated by the TMJ-1 and the burst width duration and the space width duration can be setup by the TMJ-2. The data having been written into the reloading register TMJ-1 and into the burst/space duration register (TLK) of the TMJ-2 will be loaded to the counter at the same time as the remote controlled data transmission starts. (Remote controlled data transmission starting bit (ST) 1) While remote controlled data transmission is being made, the contents of the burst/space duration register will be loaded to the counter only while reloading is being made by underflow signals. Even when a writing is made to the burst/space duration register while remote controlled data transmission is being made, reloading operation will not be made until an underflow signal is issued. The TMJ-2 issues TMJ2I interrupt requests by the underflow signals. The TMJ-1 performs normal reloading operation (including the TMJ1I interrupt requests). Figure 14.2 shows the output waveform for the remote controlled data transmission function. When a shift to the low power consumption mode is effected while remote controlled data transmission is being made, the ST bit will be cleared to 0. When resuming the remote controlled data transmission after returning to the active mode, write 1.

Consequently, when the TLK is updated during the period after setting the ST bit to 1 until the next cycle of the inputting clock comes, the initial burst width will be changed like shown in figure 14.4. Therefore, when making remote controlled data transmission, determine I/O of the TGL bit at the time of the first burst width control operation without fail. (Or, set the space width to the TLK after waiting for a cycle of the inputting clock.) After that, operations can be continued by interrupts. Similarly, pay attention to the control works when ending remote controlled data transmission. Exemple) 1) 2) 3) 4) 5] 6] Set the burst width with the TLK.

The timer L mode register (LMR) is an 8-bit read/write register which works to control the interrupts, to select between up-counting and down-counting and to select the clock source. When reset, the LMR is initialized to H'30. Bit 7: Timer L Interrupt Requesting Flag (LMIF) This is the Timer L interrupt requesting flag. It indicates occurrence of overflow or underflow of the LTC or occurrence of compare match clear.

When the Timer L is being controlled to the up-counting function, when a compare match value is set to the RCR, the LTC will be cleared at the same time and the LTC will then start counting up from the initial value (H'00). While, when the Timer L is being controlled to the down-counting function, when a reloading value is set to the RCR, the same value will be loaded to the LTC at the same time and the LTC will then start counting up from said value. Also, when the LTC underflows, the value of the RCR will be reloaded to the LTC. When reset, the RCR is initialized to H'00.

When the MSTP12 bit is set to 1, the Timer L stops its operation at the ending point of the bus cycle to shift to the module stop mode. For more information, see section 4.5, Module Stop Mode.

The inputting clock for the Timer L can be selected by the LMR2 to LMR0 bits of the LMR from the choices of the internal clock (/128 and /64), DVCDG2, PB and REC-CTL. The Timer L is provided with three different types of operation modes, namely, the compare match clear mode when controlled to the up-counting function, the auto reloading mode when controlled to the down-counting function and the interval timer mode. Respective operation modes and operation methods will be explained below. 15.3.1 Compare Match Clear Operation When the LMR3 bit of the LMR is cleared to 0, the Timer L will be controlled to the upcounting function. When any other values than H'00 are written into the RCR, the LTC will be cleared to H'00 simultaneously before starting counting up. Figure 15.2 shows the clear timing of the LTC. When the LTC value and the RCR value match (compare match), the LTC readings will be cleared to H'00 to resume counting from H'00.

It carries VCR mode identification function and slow tracking function in addition to the reloading function and event counter function. 16.1.1 Features The Timer R consists of triple 8-bit reloading timers. By combining the functions of three units of reloading timers/counters and by combining three units of timers, it can be used for the following applications: (1) Applications making use of the functions of three units of reloading timers. (2) For identification of the VCR mode. (3) For reel controls. (4) For acceleration and braking of the capstan motor when being applied to intermittent movements. (5) Slow tracking mono-multi applications. 16.1.2 Block Diagram The Timer R consists of three units of reload timer counters, namely, two units of reload timer counters equipped with capturing function (TMRU-1 and TMRU-2) and a unit of reload timer counter (TMRU-3).

When reset, the TMRM2 is initialized to H'00. Note: * The CAPF bit and the SLW bit, respectively, works to latch the interrupt causes and writing 0 only is valid. Consequently, when these bits are being set to 1, respective interrupt requests will not be issued. Therefore, it is necessary to check these bits during the course of the interrupt processing routine to have them cleared.

During the course of the capturing operation, the TMRU-1 counter readings are captured by the TMRCP1 at the CFG edge or the IRQ3 edge. The capturing operation of the TMRU-1 is being performed using 16 bits, in combination with the capturing operation of the TMRU-2. The TMRCP1 is an 8-bit read only register. When reset, the TMRCS is initialized to H'FF. Notes: 1. When the TMRCP1 is readout while the capture signal is being received, the reading data become unstable. Pay attention to the timing for reading out. 2. When a shift to the low power consumption mode is made while the capturing operating is in progress, the counter reading becomes unstable.

When a load value is set to the TMRL1, the same value will be set to the TMRU-1 counter simultaneously and the counter starts counting down from the set value. Also, when the counter underflows during the course of the reload timer operation, the TMRL1 value will be set to the counter. When reset, the TMRL1 is initialized to H'FF.

When a load value is set to the TMRL2, the same value will be set to the TMRU-2 counter simultaneously and the counter starts counting down from the set value. Also, when the counter underflows or a CFG edge is detected during the course of the reload timer operation, the TMRL2 value will be set to the counter. When reset, the TMRL2 is initialized to H'FF. 16.2.8 Timer R Load Register 3 (TMRL3) Bit : 7 TMR37 Initial value : R/W : 1 W 6 TMR36 1 W 5 TMR35 1 W 4 TMR34 1 W 3 TMR33 1 W 2 TMR32 1 W 1 TMR31 1 W 0 TMR30 1 W The timer R load register 3 (TMRL3) is an 8-bit write only register which works to set the load value of the TMRU-3.

Also, when the counter underflows or a DVCTL edge is detected, the TMRL2 value will be set to the counter. (Reloading will be made by the underflowing signals when the DVCTL signal is selected as the clock source, and reloading will be made by the DVCTL signals when the dividing clock is selected as the clock source.) When reset, the TMRL3 is initialized to H'FF.

When the MSTP11 bit is set to 1, the Timer R stops its operation at the ending point of the bus cycle to shift to the module stop mode. For more information, see section 4.5, Module Stop Mode. When reset, the MSTPCR is initialized to H'FFFF. Bit 3: Module Stop (MSTP11) This bit works to designate the module stop mode for the Timer R.

The clock source can be selected from among the leading edge of the CFG signals and three types of dividing clocks. It is also selectable whether using it as a reload counter or as a capture counter. Even when the capturing function is selected, the counter readings can be updated by writing the values into the reloading register. When the counter underflows, the TMRI1 interrupt request will be issued. The initial values of the TMRU-1 counter, reloading register and capturing register are all H'FF. (1) Operation of the Reload Timer When a value is written into to the reloading register, the same value will be written into the counter simultaneously. Also, when the counter underflows, the reloading register value will be reloaded to the counter. The TMRU-1 is a dividing circuit for the CFG. In combination with the TMRU-2 and TMRU-3, it can also be used for the mode identification purpose. (2) Capturing Operation Capturing operation is carried out in combination with the TMRU-2 using the combined 16 bits. It can be so programmed that the counter may be cleared by the capture signal. The CFG edges or IRQ3 edges are used as the capture signals. It is possible to issue the TMRI3 interrupt request by the capture signal. In addition to the capturing function being worked out in combination with the TMRU-2, the TMRU-1 can be used as a 16-bit CFG counter. Selecting the IRQ3 as the capture signal, the CFG within the duration of the reel pulse being input into the ,54 pin can be counted by the TMRU-1. Rev. 2.0, 11/00, page 345 of 1037 16.3.2 Reload Timer Counter Equipped with Capturing Function TMRU-2 The reload timer counter equipped with capturing function, TMRU-2, consists of an 8-bit downcounter, a reloading register and a capture register. The clock source can be selected from among the undedrflowing signal of the TMRU-1 and three types of dividing clocks. Also, although the reloading function is workable during its capturing operation, equipping or not of the reloading function is selectable. Even when without-reloading-function is chosen, the counter reading can be updated by writing the values to the reloading register. When the counter underflows, the TMRI2 interrupt request will be issued. The initial values of the TMRU-2 counter, reloading register and capturing register are all H'FF. (1) Operation of the Reload Timer When a value is written into to the reloading register, the same value will be written into the counter, simultaneously. Also, when the counter underflows, the reloading register value will be reloaded to the counter. The TMRU-2 can make acceleration and braking work for the capstan motor using the reload timer operation. (2) Capturing Operation Using the capture signals, the counter reading can be latched into the capturing register. As the capture signal, you can choose from among edges of the CFG, edges of the IRQ3 or the underflow signals of the TMRU-3. It is possible to issue the TMRI3 interrupt request by the capture signal. The capturing function (stopping the reloading function) of the TMRU-2, in combination with the TMRU-1 and TMRU-3, can also be used for the mode identification purpose. 16.3.3 Reload Counter Timer TMRU-3 The reload counter timer TMRU-3 consists of an 8-bit down-counter and a reloading register. Its clock source can be selected from between the undedrflowing signal of the counter and the edges of the DVCTL signals. (When the DVCTL signal is selected as the clock source, reloading will be effected by the underflowing signals and when the dividing clock is selected as the clock source, reloading will be effected by the DVCTL signals.) The reloading signal works to reload the reloading register value into the counter. Also, when a value is written into to the reloading register, the same value will be written into the counter, simultaneously. The initial values of the counter and the reloading register are H'FF. The underflowing signals can be used as the capturing signal for the TMRU-2. The TMRU-3 can also be used as a dividing circuit for the DVCTL. Also, in combination with the TMRU-1 and TMRU-2 (capturing function), the TMRU-3 can be used for the mode identification purpose. Since the divided signals of the DVCTL are being used as the clock source, CTL signals (DVCTL) conforming to the double speed can be input when making Rev. 2.0, 11/00, page 346 of 1037 searches. These DVCTL signals can also be used for phase controls of the capstan motor. Also, by selecting the dividing clock as the clock source, it is possible to make a delay with the edges of the DVCTL to provide the slow tracking mono-multi function. 16.3.4 Mode Identification When making mode identification (2/4/6 identification) of the SP/LP/EP modes of reproducing tapes, the TMRU-1 (CFG dividing circuit), TMRU-2 (capturing function/without reloading function) and TMRU-3 (DVCTL dividing circuit) of the Timer R should be used. The Timer R will become to the aforementioned status after a reset. Under the aforementioned status, the divided CFG should be written into the reloading register of the TMRU-1 and divided DVCTL should be written into the reloading register of the TMRU3. When the TMRU-3 underflows, the counter value of the TMRU-2 is captured. Such capturing register value represents the number of the CFG within the DVCTL cycle. As aforementioned, the Timer R can work to count the number of the CFG corresponding to "n" times of DVCTL's or to identify the mode being searched. For exemplary settings for the register, see section 16.5.1, Mode Identification. 16.3.5 Reeling Controls CFG counts can be captured by making 16-bit capturing operation combining the TMRU-1 and TMRU-2. By choosing the IRQ3 as the capture signal, and by counting the CFG within the duration of the reel pulse being input through the ,54 pin, reeling controls, etc. can be effected. For exemplary settings for the register, see section 16.5.2, Reeling Controls. 16.3.6 Acceleration and Braking Processes of the Capstan Motor When making intermittent movements such as those for slow reproductions or for still reproductions, it is necessary to conduct quick accelerations and abrupt stoppings of the capstan motor. The acceleration and braking processes will function to check if the revolution of a capstan motor has reached the prescribed rate when accelerated or braked. For this purpose, the TMRU-2 (reloading function) should be used. When making accelerations: (1) Set the AC/BR bit of the TMRM1 to acceleration. (Set to 1). Also, use the rising edge of the CFG as the reloading signal. (2) Set the prescribed time on the CFG frequency to deem as the acceleration has been finished, into the reloading register. (3) The TMRU-2 will work to down-count the reloading data. Rev. 2.0, 11/00, page 347 of 1037 (4) In case the acceleration has not been finished (in case the CFG signal is not input even when the prescribed time has elapsed = underflowing of down-counting has occurred), such underflowing works to set to CFG mask F/F (masking movement) and the reload timer will be cleared by the CFG. (5) When the acceleration has been finished (when the CFG signal is input before the prescribed time has elapsed = reloading movement has been made before the down counter underflows), an interrupt request will be issued because of the CFG. When making breaking: (1) Set the AC/BR bit of the TMRM1 to braking. (Clear to 0). Also, use the rising edge of the CFG as the reloading signal. (2) Set the prescribed time on the CFG frequency to deem as the braking has been finished, into the reloading register. (3) The TMRU-2 will work to down-count the reloading data. (4) In case the braking has not been finished (when the CFG signal is input before the prescribed time has elapsed = reloading movement has been made before the down counter underflows), the reload timer movement will continue. (5) When the acceleration has been finished (when the CFG signal is not input even when the prescribed time has elapsed = underflowing of down-counting has occurred), interrupt request will be issued because of the underflowing signal. The acceleration and braking processes should be employed when making special reproductions, in combination with the slow tracking mono-multi function being outlined below. For exemplary settings for the register, see section 16.5.4, Acceleration and Braking Processes of the Capstan Motor. 16.3.7 Slow Tracking Mono-multi Function When performing slow reproductions or still reproductions, the braking timing for the capstan motor is determined by use of the edge of the DVCTL signal. The slow tracking mono-multi function works to measure the time from the rising edge of the DVCTL signal down to the desired point to issue the interrupt request. In actual programming, this interrupt should be used to activate the brake of the capstan motor. The TMRU-3 should be used to perform time measurements for the slow tracking mono-multi function. Also, the braking process can be made using the TMRU-2. Figure 16.2 below shows the exemplary time series movements when a slow reproduction is being performed. For exemplary settings for the register, see section 16.5.3, Slow Tracking Mono-multi Function.

(a) Interrupts being caused by the underflowing of the TMRU-1 (TMRI1) These interrupts will constitute the timing for reloading with the TMRU-1. (b) Interrupts being caused by the underflowing of the TMRU-2 or by an end of the acceleration or braking process (TMRI2) When interrupts occur at the reload timing of the TMRU-2, clear the AC/BR (acceleration/braking) bit of the timer R mode register 1 (TMRM1) to 0. (c) Interrupts being caused by the capture signals of the TMRU-3 and by ending the slow tracking mono-multi process (TMRI3) Since these two interrupt causes are constituting the OR, it becomes necessary to determine which interrupt cause is occurring using the software. Respective interrupt causes are being set to the CAPF flag or the SLW flag of the timer R mode register 2 (TMRM2), have the software determine which. Since the CAPF flag and the SLW flag will not be cleared automatically, program the software to clear them. (Writing 0 only is valid for these flags.) Unless these flags are cleared, detection of the next cause becomes unworkable. Also, if the CP/SLM bit is changed leaving these flags un-cleared as they are, these flags will get cleared. Rev. 2.0, 11/00, page 350 of 1037 16.5 16.5.1 Exemplary Settings for Respective Functions Mode Identification When making mode identification (2/4/6 identification) of the SP/LP/EP modes of reproducing tapes, the TMRU-1 (CFG dividing circuit), TMRU-2 (capturing function/without reloading function) and TMRU-3 (DVCTL dividing circuit) of the Timer R should be used. The Timer R will become to the aforementioned status after a reset. Under the aforementioned status, the divided CFG should be written into the reloading register of the TMRU-1 and divided DVCTL should be written into the reloading register of the TMRU3. When the TMRU-3 underflows, the counter value of the TMRU-2 is captured. Such capturing register value represents the number of the CFG within the DVCTL cycle. As aforementioned, the Timer R can work to count the number of the CFG corresponding to "n" times of DVCTL's or to identify the mode being searched. * Exemplary settings (1) Setting the timer R mode register 1 (TMRM1) CLR2 bit (Bit 7) = 1: Works to clear after making the TMRU-2 capture.

PS31 and PS30 (Bits 4 and 3) = (0 and 0): The leading edge of the DVCTL signal is to be used as the clock source for the TMRU-3. CP/SLM bit (Bit 2) = 0: The capture signal is to work to issue the TMRI3 interrupt request. (3) Setting the timer R load register 1 (TMRL1) Set the dividing value for the CFG. The set value should become (n - 1) when divided by "n". (4) Setting the timer R load register 3 (TMRL3) Set the dividing value for the DVCTL. The set value should become (n - 1) when divided by "n". Rev. 2.0, 11/00, page 351 of 1037 16.5.2 Reeling Controls CFG counts can be captured by making 16-bit capturing operation combining the TMRU-1 and TMRU-2. By choosing the IRQ3 as the capture signal, and by counting the CFG within the duration of the reel pulse being input through the ,54 pin, reeling controls, etc. can be effected. * Exemplary settings (1) Setting P13/,54 pin as the ,54 pin Set the PMR13 bit (Bit 3) of the port mode register 1 (PMR1) to 1. See section 22.2.2, Port Mode Register (PMR1). (2) Setting the timer R mode register 1 (TMRM1) CLR2 bit (Bit 7) = 1: Works to clear after making the TMRU-2 capture.

RLD/CAP bit (Bit 1) = 1: The TMRU-1 has been set to make the capturing operation. CPS bit (Bit 0) = 1: The edge of the IRQ3 signal is to be used as the capture signal for the TMRU-1 and TMRU-2. (3) Setting the timer R mode register 2 (TMRM2) LAT bit (Bit 7) = 1: The edge of the IRQ3 signal is to be used as the capture signal for the TMRU-1 and TMRU-2. PS11 and PS10 (Bits 6 and 5) = (0 and 0): The rising edge of the CFG signal is to be used as the clock source for the TMRU-1. CP/SLM bit (Bit 2) = 0: The capture signal is to work to issue the TMRI3 interrupt request. 16.5.3 Slow Tracking Mono-multi Function When performing slow reproductions or still reproductions, the braking timing for the capstan motor is determined by use of the edge of the DVCTL signal. The slow tracking mono-multi function works to measure the time from the leading edge of the DVCTL signal down to the desired point to issue the interrupt request. In actual programming, this interrupt should be used to activate the brake of the capstan motor. The TMRU-3 should be used to perform time measurements for the slow tracking mono-multi function. Also, the braking process can be made using the TMRU-2. * Exemplary settings (1) Setting the timer R mode register 2 (TMRM2) PS31 and PS30 (Bits 4 and 3) = Other than (0, 0): The dividing clock is to be used as the clock source for the TMRU-3. CP/SLM bit (Bit 2) = 1: The slow tracking delay signal is to work to issue the TMRI3 interrupt request. Rev. 2.0, 11/00, page 352 of 1037 (2) Setting the timer R load register 3 (TMRL3) Set the slow tracking delay value. When the delay count is "n", the set value should be (n - 1). Regarding the delaying duration, see figure 16.2 Exemplary time series movements when a slow reproduction is being performed. 16.5.4 Acceleration and Braking Processes of the Capstan Motor When making intermittent movements such as those for slow reproductions or for still reproductions, it is necessary to conduct quick accelerations and abrupt stoppings of the capstan motor. The acceleration and braking processes will function to check if the revolution of a capstan motor has reached the prescribed rate when accelerated or braked.

The inputting clock is to be selected from the CKS1 and CKS0 of the TCRX. By the setting of the CCLRA bit of the TCSRX, the FRC can be cleared by comparing match A. When the FRC overflows (H'FFFF H'0000), the OVF of the TCSRX will be set to 1. At this time, when the OVIE of the TIER is being set to 1, an interrupt request will be issued to the CPU. Reading/writing can be made from and to the FRC through the CPU at 8-bit or 16-bit. The FRC is initialized to H'0000 when reset or under the standby mode, watch mode, subsleep mode, module stop mode or subactive mode.

The contents of the OCR are always being compared with the FRC and, when the value of these two match, the OCFA and OCRB of the TCSRX will be set to 1. At this time, if the OCIAE and OCIB of the TIER are being set to 1, an interrupt request will be issued to the CPU. When performing compare matching, if the OEA and OEB of the TOCR are being set to 1, the level value having been set to the OLVLA and OLVLB of the TOCR will be output through the FTOA and FTOB pins. After resetting, 0 will be output through the FTOA and FTOB pins until the first compare matching occurs. Reading/writing can be made from and to the OCR through the CPU at 8-bit or 16-bit. The OCR is cleared to H'FFFF when reset or under the standby mode, watch mode, subsleep mode, module stop mode or subactive mode.

When the falling edge of the input capture input signal is detected, the value is transferred to the ICRA through ICRD. At this time, the ICFA through ICFD of the TCSRX are set to 1 simultaneously. At this time, if the IDIAE through IDIDE of the TCRX are all being set to 1, due interrupt request will be issued to the CPU. The edge of the input signal can be selected by setting the IEDGA through IEDGD of the TCRX. Also, the ICRC and ICRD can be used as the buffer register, respectively, of the ICRA and ICRB by setting the BUFEA and BUFEB of the TCRX to perform buffer operations. Figure 17.2 shows the connections necessary when using the ICRC as the buffer register of the ICRA. (BUFEA = 1) When the ICRC is used as the buffer of the ICRA, by setting IEDGA IEDGC, both of the rising and falling edges can be designated for use. In case of IEDGA = IEDGC, either one of the rising edge or the falling edge only is usable. Regarding selection of the input signal edge, see table 17.3. Note: Transference from the FRC to the ICR will be performed regardless of the value of the ICF.

For stable input capturing operation, maintain the pulse duration of the input capture input signals at 1.5 system clock () or more in case of single edge capturing and at 2.5 system clock () or more in case of both edge capturing.

The TCSRX is an 8-bit register which works to select counter clearing timing and to control respective interrupt requesting signals. The TCSRX is initialized to H'00 when reset or under the standby mode, watch mode, subsleep mode, module stop mode or subactive mode. Meanwhile, as for the timing, see section 17.3, Operation. The FTIA through FTID pins are for fixed inputs inside the LSI under the low power consumption mode excluding the sleep mode. Consequently, when such shifts as "active mode low power consumption mode active mode" are made, wrong edges may be detected depending on the pin status or on the type of the detecting edge. To avoid such error, clear the interrupt requesting flag once immediately after shifting to the active mode from the low power consumption mode. Bit 7: Input Capture Flag A (ICFA) This is a status flag indicating the fact that the value of the FRC has been transferred to the ICRA by the input capture signals. When the BUFEA of the TCRX is being set to 1, the ICFA indicates the status that the FRC value has been transferred to the ICRA by the input capture signals and that the ICRA value before being updated has been transferred to the ICRC. This flag should be cleared by use of of the software. Such setting should only be made by use of the hardware. It is not possible to make this setting using a software.

When an input capture signal occurs while the BUFEA of the TCRX is being set to 1, although the ICFC will be set out, data transference to the ICRC will not be performed. Therefore, in buffer operation, the ICFC can be used as an external interrupt by setting the ICICE bit to 1. This flag should be cleared by use of the software. Such setting should only be made by use of the hardware. It is not possible to make this setting using a software.

After resetting, 0 will be output through the FTOA and FTOB pins until the first compare matching occurs. Also, when the CCLRA of the TCSRX is being set to 1, the FRC will be cleared to H'0000 when the comparing match A occurs. (2) Input Capturing Operation Right after resetting, the FRC is initialized to H'0000 to start counting up. The inputting clock can be selected from among three different types of internal clocks or the external clock by setting the CKS1 and CKS0 of the TCRX. The inputs are transferred to the IEDGA through IEDGD of the TCRX through the FTIA through FTID pins and, at the same time, the ICFA through ICFD of the TCSRX are set to 1. At this time, if the ICIAE through ICIED of the TIER are being set to 1, due interrupt request will be issued to the CPU. When the BUFEA and BUFEB of the TCRX are set to 1, the ICRC and ICRD work as the buffer register, respectively, of the ICRA and ICRB. When the edge selected by setting the IEDGA through IEDGD of the TCRX is input through the FTIA and FTIB pins, the value at the time of the FRC is transferred to the ICRA and ICRB and, at the same time, the values of the ICRA and ICRB before updating are transferred to the ICRC and ICRD. At this time, when the ICFA and ICFB are being set to 1 and if the ICIAE and ICIBE of the TIER are being set to 1, due interrupt request will be issued to the CPU. Rev. 2.0, 11/00, page 376 of 1037 17.3.2 Counting Timing of the FRC The FRC is counted up by the inputting clock. By setting the CKS1 and CKS0 of the TCRX, the inputting clock can be selected from among three different types of clocks (/4, /16 and /64) and the DVCFG. (1) In Case of Internal Clock Operation By setting the CKS1 and CKS0 bits of the TCRX, three types of internal clocks (/4, /16 and /64), generated by dividing the system clock () can be selected. Figure 17.3 shows the timing chart at this time. Internal clock FRC input clock FRC N-1 N N+1 Figure 17.3 Count Timing in Case of Internal Clock Operation (2) In Case of DVCFG Clock Operation By setting the CKS1 and CKS0 bits of the TCRX to 1, DVCFG clock input can be selected. The DVCFG clock makes counting by use of the edge detecting pulse being selected by the CFG dividing timer. Figure 17.4 shows the timing chart at this time.

For example, when using the ICRC as the buffer register for the ICRA, when an edge change having been designated by the IEDGC bit is detected with the input capture signals C and if the ICIEC bit is duly set, an interrupt request will be issued. However, in this case, the FRC value will not be transferred to the ICRC. 17.3.6 Input Capture Flag (ICFA through ICFD) Setting Up Timing The input capture signal works to set the ICFA through ICFD to "1" and, simultaneously, the FRC value is transferred to the corresponding ICRA through ICRD. Figure 17.9 shows the timing chart for the above.

The comparing match signal is generated at the last state of the value match (the timing of the FRC's updating the matching count reading). After the values of the OCRA, OCRB and FRC match, up until the count up clock signal is generated, the comparing match signal will not be issued.

Table 17.6 indicated below shows the relations between the timing of changing over the internal clocks (Re-writing of the CKS1 and CKS0) and the FRC operations. When using an internal clock, the counting clock is being generated detecting the falling edge of the internal clock dividing the system clock (). For this reason, like Item No. 3 of table 17.6, count clock signals are issued deeming the timing before the changeover as the falling edge to have the FRC to count up. Also, when changing over between an internal clock and the external clock, the FRC may count up.

Rev. 2.0, 11/00, page 389 of 1037 Rev. 2.0, 11/00, page 390 of 1037 Section 18 Watchdog Timer (WDT) 18.1 Overview This LSI has an on-chip watchdog timer with one channel (WDT) for monitoring system operation. The WDT outputs an overflow signal if a system crash prevents the CPU from writing to the timer counter, allowing it to overflow. At the same time, the WDT can also generate an internal reset signal or internal NMI interrupt signal. When this watchdog function is not needed, the WDT can be used as an interval timer. In interval timer mode, an interval timer interrupt is generated each time the counter overflows. 18.1.1 Features WDT features are listed below. * Switchable between watchdog timer mode and interval timer mode -- WOVI interrupt generation in interval timer mode * Internal reset or internal interrupt generated when the timer counter overflows -- Choice of internal reset or NMI interrupt generation in watchdog timer mode * Choice of 8 counter input clocks -- Maximum WDT interval: system clock period x 131072 x 256 Rev. 2.0, 11/00, page 391 of 1037 18.1.2 Block Diagram Figure 18.1 shows block diagram of WDT.

Bit 3: External Reset (XRST) Indicates the reset source. When the watchdog timer is used, a reset can be generated by watchdog timer overflow in addition to external reset input. XRST is a read-only bit. It is set to 1 by an external reset, and cleared to 0 by watchdog timer overflow. Bit 3 XRST 0 1 Description Reset is generated by watchdog timer overflow Reset is generated by external reset input (Initial value) 18.2.4 Notes on Register Access The watchdog timer's WTCNT and WTCSR registers differ from other registers in being more difficult to write to. The procedures for writing to and reading these registers are given below. (1) Writing to WTCNT and WTCSR These registers must be written to by a word transfer instruction. They cannot be written to with byte transfer instructions. Figure 18.2 shows the format of data written to WTCNT and WTCSR. WTCNT and WTCSR both have the same write address. For a write to WTCNT, the upper byte of the written word must contain H'5A and the lower byte must contain the write data. For a write to WTCSR, the upper byte of the written word must contain H'A5 and the lower byte must contain the write data. This transfers the write data from the lower byte to WTCNT or WTCSR. Rev. 2.0, 11/00, page 397 of 1037 Figure 18.2 Format of Data Written to WTCNT and WTCSR (2) Reading WTCNT and WTCSR These registers are read in the same way as other registers. The read addresses are H'FFBC for WTCSR, and H'FFBD for WTCNT. Rev. 2.0, 11/00, page 398 of 1037 18.3 18.3.1 Operation Watchdog Timer Operation To use the WDT as a watchdog timer, set the WT/,7 and TME bits in WTCSR to 1. Software must prevent WTCNT overflows by rewriting the WTCNT value (normally by writing H'00) before overflow occurs. This ensures that WTCNT does not overflow while the system is operating normally. If WTCNT overflows without being rewritten because of a system crash or other error, the chip is reset, or an NMI interrupt is generated, for 518 system clock periods (518 ). This is illustrated in figure 18.3. An internal reset request from the watchdog timer and reset input from the 5(6 pin are handled via the same vector. The reset source can be identified from the value of the XRST bit in SYSCR. If a reset caused by an input signal from the 5(6 pin and a reset caused by WDT overflow occur simultaneously, the 5(6 pin reset has priority, and the XRST bit in SYSCR is set to 1. An NMI interrupt request from the watchdog timer and an interrupt request from the NMI pin are handled via the same vector. Simultaneous handling of a watchdog timer NMI interrupt request and an NMI pin interrupt request must therefore be avoided.

XRST is cleared to 0. Figure 18.3 Operation in Watchdog Timer Mode Rev. 2.0, 11/00, page 399 of 1037 18.3.2 Interval Timer Operation To use the WDT as an interval timer, clear the WT/,7 bit in WTCSR to 0 and set the TME bit to 1. An interval timer interrupt (WOVI) is generated each time WTCNT overflows, provided that the WDT is operating as an interval timer, as shown in figure 18.4. This function can be used to generate interrupt requests at regular intervals.

At the same time, an interval timer interrupt (WOVI) is requested. This timing is shown in figure 18.5. If NMI request generation is selected in watchdog timer mode, when WTCNT overflows the OVF bit in WTCSR is set to 1 and at the same time an NMI interrupt is requested.

The interval timer interrupt is requested whenever the OVF flag is set to 1 in WTCSR. OVF must be cleared to 0 in the interrupt handling routine. When NMI interrupt request generation is selected in watchdog timer mode, an overflow generates an NMI interrupt request. 18.5 18.5.1 Usage Notes Contention between Watchdog Timer Counter (WTCNT) Write and Increment If a timer counter clock pulse is generated during the T2 state of a WTCNT write cycle, the write takes priority and the timer counter is not incremented.

Software must stop the watchdog timer (by clearing the TME bit to 0) before changing the value of bits CKS2 to CKS0. 18.5.3 Switching between Watchdog Timer Mode and Interval Timer Mode If the mode is switched from watchdog timer to interval timer, or vice versa, while the WDT is operating, errors could occur in the incrementation. Software must stop the watchdog timer (by clearing the TME bit to 0) before switching the mode.

These PWMs use the pulse-pitch control method (periodically overriding part of the output). This reduces lowfrequency components in the pulse output, enabling a quick response without increasing the clock frequency. The pitch of the PWM signal is modified in response to error data (representing lead or lag in relation to a preset speed and phase). Rev. 2.0, 11/00, page 413 of 1037 20.1.2 Block Diagram Figure 20.1 shows a block diagram of the 12-bit PWM (1 channel). The PWM signal is generated by combining quantizing pulses from a 12-bit pulse generator with quantizing pulses derived from the contents of a data register. Low-frequency components are reduced because the two quantizing pulses have different frequencies. The error data is represented by an unsigned 12-bit binary number. /2 /4 /8 /16 /32 /64 /128 CAPPWM or DRMPWM Counter Pulse generator Output control circuit PWM data register PWM control register Error data * DFUCR Internal data bus [Legend] CAPPWM : Capstan mix pin DRMPWM : Drum mix pin Digital filter circuit PTON CP/DP Figure 20.1 Block Diagram of 12-Bit PWM (1 channel) Rev. 2.0, 11/00, page 414 of 1037 20.1.3 Pin Configuration Table 20.1 shows the 12-bit PWM pin configuration.

Bit 7: Polarity Invert (POL) This bit can invert the polarity of the modulated PWM signal for noise suppression and other purposes. This bit is invalid when fixed output is selected (when bit DC is set to 1). Bit 7 POL 0 1 Description Output with positive polarity Output with inverted polarity (Initial value) Bit 6: Output Select (DC) Selects either PWM modulated output, or fixed output controlled by the pin output bits (Bits 5 and 4). Rev. 2.0, 11/00, page 416 of 1037 Bits 5 and 4: PWM Pin Output (HiZ, H/L) When bit DC is set to 1, the 12-bit PWM output pins (CAPPWM, DRMPWM) output a value determined by the HiZ and H/L bits. The output is not affected by bit POL. In power-down modes, the 12-bit PWM circuit and pin statuses are retained. Before making a transition to a power-down mode, first set bits 6 (DC), 5 (HiZ), and 4 (H/L) of the 12-bit PWM control registers (CPWCR and DPWCR) to select a fixed output level.

The data in these registers is converted to PWM output only when bit SF/DF of the corresponding control register is set to 1. The error data from the digital filter circuit is written in the data register, and then modulated by PWM. At this time, the error data from the digital filter circuit can be monitored by reading the data register. These registers can be accessed by word only, and cannot be accessed by byte. Byte access gives unassured results. CPWDR and DPWDR are initialized to H'F000 by a reset, or in sleep mode, standby mode, watch mode, subactive mode, subsleep mode, or module stop mode of the servo circuit.

When Vcc/2 is set as the reference value, the following conditions apply: * When the motor is running at the correct sped and phase, the PWM signal is output with a 50% duty cycle. * When the motor is running behind the correct speed or phase, it is corrected by periodically holding part of the PWM signal low. The part held low depends on the size of the error. * When the motor is running ahead of the correct speed or phase, it is corrected by periodically holding part of the PWM signal high. The part held high depends on the size of the error. When the motor is running at the correct speed and phase, the error data is a 12-bit value representing 1/2 (1000 0000 0000), and the PWM output has the same frequency as the selected division clock. After the error data has been converted into a PWM signal, the PWM signal can be smoothed into a DC voltage by an external low-pass filter (LPF). The smoothes error data can be used to control the motor. Figure 20.2 shows sample waveform outputs. The 12-bit PWM pin outputs a low-level signal upon reset, in power-down mode or at modulestop.

PWDRU and PWDRL form a 14-bit write-only register, with the upper 6 bits assigned to PWDRU and the lower 8 bits to PWDRL. The value written in PWDRU and PWDRL gives the total high-level width of one PWM waveform cycle. Both PWDRU and PWDRL are accessible by byte access only. Word access gives unassured results. When 14-bit data is written in PWDRU and PWDRL, the contents are latched in the PWM waveform generator and the PWM waveform generation data is updated. When writing the 14bit data, follow these steps: (1) Write the lower 8 bits to PWDRL. (2) Write the upper 6 bits to PWDRU. Write the data first to PWDRL and then to PWDRU. PWDRU and PWDRL are write-only registers. When read, all bits always read 1. PWDRU and PWDRL are initialized to H'C000 by a reset.

When the MSTP5 bit is set to 1, the 14-bit PWM operation stops at the end of the bus cycle and a transition is made to module stop mode. For details, see section 4.5, Module Stop Mode. MSTPCR is initialized to H'FFFF by a reset. Bit 5: Module Stop (MSTP5) Specifies the module stop mode of the 14-bit PWM. MSTPCRL Bit 5 MSTP5 0 1 Description 14-bit PWM module stop mode is released 14-bit PWM module stop mode is set (Initial value) Rev. 2.0, 11/00, page 428 of 1037 21.3 14-Bit PWM Operation When using the 14-bit PWM, set the registers in this sequence: (1) Set bit PMR40 to 1 in port mode register 4 (PMR4) so that pin P40/PWM14 is designated for PWM output. (2) Set bit PWCR0 in the PWM control register (PWCR) to select a conversion period of either 32768/ (PWCR0 = 1) or 16384/ (PWCR0 = 0). (3) Set the output waveform data in PWM data registers U and L (PWDRU, PWDRL). Be sure to write byte data first to PWDRL and then to PWDRU. When the data is written in PWDRU, the contents of these registers are latched in the PWM waveform generator, and the PWM waveform generation data is updated in synchronization with internal signals. One conversion period consists of 64 pulses, as shown in figure 21.2. The total high-level width during this period (TH) corresponds to the data in PWDRU and PWDRL. This relation can be expressed as follows: TH = (data value in PWDRU and PWDRL + 64) x t/2 where t is the period of PWM clock input: 2/ (bit PWCR0 = 0) or 4/ (bit PWCR0 = 1). If the data value in PWDRU and PWDRL is from H'3FC0 to H'3FFF, the PWM output stays high. When the data value is H'0000, TH is calculated as follows: TH = 64 x t/2 = 32 t 1 conversion period t f1 t f2 t f63 t f64 t H1 t H2 t H3 t H63 t H64 T H = t H1 + t H2 + t H3 + ... + t H64 t f1 = t f2 = t f3 = ... = t f64 Figure 21.2 Waveform Output by 14-Bit PWM Rev. 2.0, 11/00, page 429 of 1037 Rev. 2.0, 11/00, page 430 of 1037 Section 22 Prescalar Unit 22.1 Overview The prescalar unit (PSU) has a 18-bit free running counter (FRC) that uses as a clock source and a 5-bit counter that uses W as a clock source. 22.1.1 Features * Prescalar S (PSS): Generates frequency division clocks that are input to peripheral functions. * Prescalar W (PSW): When a timer A is used as a clock time base, the PSW frequency-divides subclocks and generates input clocks. * Stable oscillation wait time count: During the return from the low power consumption mode excluding the sleep mode, the FRC counts the stable oscillation wait time. * 8-bit PWM The lower 8 bits of the FRC is used as 8-bit PWM cycle and duty cycle generation counters.

The circuit can be used for noise protection such as remote control receiving. The noise cancel circuit samples the input values of the ,& pin twice at an interval of 256 states. If the input values are different, they are assumed to be noise. The ,& pin can specify enable/disable of the noise cancel function according to the bit 4 (NCon/off) of the prescalar unit control/status register (PCSR). Rev. 2.0, 11/00, page 437 of 1037 22.4 22.4.1 Operation Prescalar S (PSS) The PSS is a 17-bit counter that uses the system clock (=fosc) as an input clock and generates the frequency division clocks (/131072 to /2) of the peripheral function. The low-order 17 bits of the 18-bit free running counter (FRC) correspond to the PSS. The FRC is incremented by one clock. The PSS output is shared by the timer and serial communication interface (SCI), and the frequency division ratio can independently be set by each built-in peripheral function. When reset, the FRC is initialized to H'00000, and starts increment after reset has been released. Because the system clock oscillator is stopped in standby mode, watch mode, subactive mode, and subsleep mode, the PSS operation is also stopped. In this case, the FRC is also initialized to H'00000. The FRC cannot be read and written from the CPU. Rev. 2.0, 11/00, page 438 of 1037 22.4.2 Prescalar W (PSW) PSW is a counter that uses the subclock as an input clock. The PSW also generates the input clock of the timer A. In this case, the timer A functions as a clock time base. When reset, the PSW is initialized to H'00, and starts increment after reset has been released. Even if the mode has been shifted to the standby mode *, watch mode *, subactive mode *, and subsleep mode *, the PSW continues the operation as long as the clocks are supplied by the X1 and X2 pins. The PSW can also be initialized to H'00 by setting the TMA3 and TMA2 bits of the timer mode register A (TMA) to 11. Note: * When the timer A is in module stop mode, the operation is stopped. Figure 22.2 shows the supply of the clocks to the peripheral function by the PSS and PSW. /131072 to /2 OSC1 System fosc clock oscillator System clock duty correction circuit Prescalar S Timer SCI OSC2 Medium speed clock frequency divider w/4 Prescalar W TMOW pin X1 Subclock oscillator X2 (fx) w Subclock frequency dividers (1/2, 1/4, and 1/8) w/128 Timer A CPU ROM RAM Peripheral register I/O port System clock selection Figure 22.2 Clock Supply 22.4.3 Stable Oscillation Wait Time Count For the count of the stable oscillation stable wait time during the return from the low power consumption mode excluding the sleep mode, see section 4, Power-Down State. Rev. 2.0, 11/00, page 439 of 1037 22.4.4 8-Bit PWM This 8-bit PWM controls the duty control PWM signal in the conversion cycle 256 states. It 7 0 counts the cycle and the duty cycle at 2 to 2 of the FRC. It can be used for controlling reel motors and loading motors. For details, see section 19, 8-Bit PWM. 22.4.5 8-Bit Input Capture Using ,& Pin 15 8 This function catches the 8-bit data of 2 to 2 of the FRC according to the edge of the ,& pin. It can be used for remote control receiving. For the edge of the ,& pin, the rising and falling edges can be selected. The ,& pin has a built-in noise cancel circuit. See section 22.3, Noise Cancel Circuit. An interrupt request is generated due to the input capture using the ,& pin. Note: Rewriting the ICEG bit, NCon/off bit, or PMR16 bit is incorrectly recognized as edge detection according to the combinations between the state and detection edge of the ,& pin and the ICIF bit may be set after up to 384 seconds. 22.4.6 Frequency Division Clock Output The frequency division clock can be output from the TMOW pin. For the frequency division clock, eight types of clocks can be selected according to the DCS2 to DCS0 bits in PCSR. The clock in which the system clock was frequency-divided is output in active mode and sleep mode and the clock in which the subclock was frequency-divided is output in active mode*, sleep mode*, and subactive mode. Note: * When the timer A is in module stop mode, no clock is output. Rev. 2.0, 11/00, page 440 of 1037 Section 23 Serial Communication Interface 1 (SCI1) 23.1 Overview The serial communication interface 1 (SCI1) can handle both asynchronous and clocked synchronous serial communication. A function is also provided for serial communication between processors (multiprocessor communication function). 23.1.1 Features SCI1 features are listed below. (1) Choice of asynchronous or clock synchronous serial communication mode (a) Asynchronous mode * Serial data communication is executed using an asynchronous system in which synchronization is achieved character by character Serial data communication can be carried out with standard asynchronous communication chips such as a Universal Asynchronous Receiver/Transmitter (UART) or Asynchronous Communication Interface Adapter (ACIA) * A multiprocessor communication function is provided that enables serial data communication with a number of processors * Choice of 12 serial data transfer formats Data length: 7 or 8 bits Stop bit length: 1 or 2 bits Parity: Even, odd, or none Multiprocessor bit: 1 or 0 * Receive error detection: Parity, overrun, and framing errors * Break detection: Break can be detected by reading the SI1 pin level directly in case of a framing error (b) Clock synchronous mode * Serial data communication is synchronized with a clock Serial data communication can be carried out with other chips that have a synchronous communication function * One serial data transfer format Data length: 8 bits * Receive error detection: Overrun errors detected Rev. 2.0, 11/00, page 441 of 1037 (2) Full-duplex communication capability * The transmitter and receiver are mutually independent, enabling transmission and reception to be executed simultaneously * Double-buffering is used in both the transmitter and the receiver, enabling continuous transmission and continuous reception of serial data (3) Built-in baud rate generator allows any bit rate to be selected (4) Choice of serial clock source: internal clock from baud rate generator or external clock from SCK1 pin (5) Four interrupt sources * Four interrupt sources (transmit-data-empty, transmit-end, receive-data-full, and receive error) that can issue requests independently Rev. 2.0, 11/00, page 442 of 1037 23.1.2 Block Diagram Figure 23.1 shows a block diagram of the SCI1.

The SCI1 sets serial data input from the SI1 pin in RSR in the order received, starting with the LSB (bit 0), and converts it to parallel data. When one byte of data has been received, it is transferred to RDR1 automatically. RSR cannot be directly read or written to by the CPU. 23.2.2 Receive Data Register (RDR1) Bit : Initial value : R/W : 7 0 R 6 0 R 5 0 R 4 0 R 3 0 R 2 0 R 1 0 R 0 0 R RDR1 is a register that stores received serial data. When the SCI1 has received one byte of serial data, it transfers the received serial data from RSR to RDR1 where it is stored, and completes the receive operation. After this, RSR is receive-enabled. Since RSR and RDR1 function as a double buffer in this way, continuous receive operations can be performed. RDR1 is a read-only register, and cannot be written to by the CPU. RDR1 is initialized to H'00 by a reset, and in standby mode, watch mode, subactive mode, subsleep mode, and module stop mode. Rev. 2.0, 11/00, page 445 of 1037 23.2.3 Transmit Shift Register (TSR) Bit : 7 -- 6 -- 5 -- 4 -- 3 -- 2 -- 1 -- 0 -- R/W : TSR is a register used to transmit serial data. To perform serial data transmission, the SCI1 first transfers transmit data from TDR1 to TSR, then sends the data to the SO1 pin starting with the LSB (bit 0). When transmission of one byte is completed, the next transmit data is transferred from TDR1 to TSR, and transmission started, automatically. However, data transfer from TDR1 to TSR is not performed if the TDRE bit in SSR1 is set to 1. TSR cannot be directly read or written to by the CPU. 23.2.4 Transmit Data Register (TDR1) Bit : Initial value : R/W : 7 1 R/W 6 1 R/W 5 1 R/W 4 1 R/W 3 1 R/W 2 1 R/W 1 1 R/W 0 1 R/W TDR1 is an 8-bit register that stores data for serial transmission. When the SCI1 detects that TSR is empty, it transfers the transmit data written in TDR1 to TSR and starts serial transmission. Continuous serial transmission can be carried out by writing the next transmit data to TDR1 during serial transmission of the data in TSR. TDR1 can be read or written to by the CPU at all times. TDR1 is initialized to H'FF by a reset, and in standby mode, watch mode, subactive mode, subsleep mode, and module stop mode. Rev. 2.0, 11/00, page 446 of 1037 23.2.5 Serial Mode Register (SMR1) Bit : 7 C/A 0 R/W 6 CHR 0 R/W 5 PE 0 R/W 4 O/E 0 R/W 3 STOP 0 R/W 2 MP 0 R/W 1 CKS1 0 R/W 0 CKS0 0 R/W Initial value : R/W : SMR1 is an 8-bit register used to set the SCI1's serial transfer format and select the baud rate generator clock source. SMR1 can be read or written to by the CPU at all times. SMR1 is initialized to H'00 by a reset, and in standby mode, watch mode, subactive mode, subsleep mode, and module stop mode. Bit 7: Communication Mode (C/) Selects asynchronous mode or clock synchronous mode as the SCI1 operating mode. Bit 7 C/ 0 1 Description Asynchronous mode Clock synchronous mode (Initial value) Bit 6: Character Length (CHR) Selects 7 or 8 bits as the data length in asynchronous mode. In synchronous mode, a fixed data length of 8 bits is used regardless of the CHR setting. Bit 6 CHR 0 1 Note: * Description 8-bit data 7-bit data* When 7-bit data is selected, the MSB (bit 7) of TDR1 is not transmitted, and LSBfirst/MSB-first selection is not available. (Initial value) Rev. 2.0, 11/00, page 447 of 1037 Bit 5: Parity Enable (PE) In asynchronous mode, selects whether or not parity bit addition is performed in transmission, and parity bit checking in reception. In synchronous mode, or when a multiprocessor format is used, parity bit addition and checking is not performed, regardless of the PE bit setting. Bit 5 PE 0 1 Note: * Description Parity bit addition and checking disabled Parity bit addition and checking enabled* When the PE bit is set to 1, the parity (even or odd) specified by the O/ bit is added to transmit data before transmission. In reception, the parity bit is checked for the parity (even or odd) specified by the O/ bit. (Initial value) Bit 4: Parity Mode (O/) Selects either even or odd parity for use in parity addition and checking. The O/ bit setting is only valid when the PE bit is set to 1, enabling parity bit addition and checking, in asynchronous mode. The O/ bit setting is invalid in synchronous mode, when parity bit addition and checking is disabled in asynchronous mode, and when a multiprocessor format is used. Bit 4 O/ 0 1 Description Even parity*1 Even parity *2 (Initial value) Notes: 1. When even parity is set, parity bit addition is performed in transmission so that the total number of 1 bits in the transmit character plus the parity bit is even. In reception, a check is performed to see if the total number of 1 bits in the receive character plus the parity bit is even. 2. When odd parity is set, parity bit addition is performed in transmission so that the total number of 1 bits in the transmit character plus the parity bit is odd. In reception, a check is performed to see if the total number of 1 bits in the receive character plus the parity bit is odd. Rev. 2.0, 11/00, page 448 of 1037 Bit 3: Stop Bit Length (STOP) Selects 1 or 2 bits as the stop bit length in asynchronous mode. The STOP bit setting is only valid in asynchronous mode. If synchronous mode is set the STOP bit setting is invalid since stop bits are not added. Bit 3 STOP 0 1 Description 1 stop bit*1 2 stop bits *2 (Initial value) Notes: 1. In transmission, a single 1 bit (stop bit) is added to the end of a transmit character before it is sent. 2. In transmission, two 1 bits (stop bits) are added to the end of a transmit character before it is sent. In reception, only the first stop bit is checked, regardless of the STOP bit setting. If the second stop bit is 1, it is treated as a stop bit; if it is 0, it is treated as the start bit of the next transmit character. Bit 2: Multiprocessor Mode (MP) Selects multiprocessor format. When multiprocessor format is selected, the PE bit and O/ bit parity settings are invalid. The MP bit setting is only valid in asynchronous mode; it is invalid in synchronous mode. For details of the multiprocessor communication function, see section 23.3.3, Multiprocessor Communication Function. Bit 2 MP 0 1 Description Multiprocessor function disabled Multiprocessor format selected (Initial value) Rev. 2.0, 11/00, page 449 of 1037 Bits 1 and 0: Clock Select 1 and 0 (CKS1, CKS0) These bits select the clock source for the baud rate generator. The clock source can be selected from , /4, /16, and /64, according to the setting of bits CKS1 and CKS0. For the relation between the clock source, the bit rate register setting, and the baud rate, see section 23.2.8, Bit Rate Register.

SCR1 can be read or written to by the CPU at all times. SCR1 is initialized to H'00 by a reset, and in standby mode, watch mode, subactive mode, subsleep mode, and module stop mode. Bit 7: Transmit Interrupt Enable (TIE) Enables or disables transmit-data-empty interrupt (TXI) request generation when serial transmit data is transferred from TDR1 to TSR and the TDRE flag in SSR1 is set to 1. Bit 7 TIE 0 1 Note: * Description Transmit-data-empty interrupt (TXI) request disabled* Transmit-data-empty interrupt (TXI) request enabled TXI interrupt request cancellation can be performed by reading 1 from the TDRE flag, then clearing it to 0, or clearing the TIE bit to 0. (Initial value) Rev. 2.0, 11/00, page 450 of 1037 Bit 6: Receive Interrupt Enable (RIE) Enables or disables receive-data-full interrupt (RXI) request and receive-error interrupt (ERI) request generation when serial receive data is transferred from RSR to RDR1 and the RDRF flag in SSR1 is set to 1. Bit 6 RIE 0 1 Note: * Description Receive-data-full interrupt (RXI) request and receive-error interrupt (ERI) request disabled* (Initial value) Receive-data-full interrupt (RXI) request and receive-error interrupt (ERI) request enabled RXI and ERI interrupt request cancellation can be performed by reading 1 from the RDRF, FER, PER, or ORER flag, then clearing the flag to 0, or clearing the RIE bit to 0. Bit 5: Transmit Enable (TE) Enables or disables the start of serial transmission by the SCI1. Bit 5 TE 0 1 Description Transmission disabled*1 Transmission enabled *2 (Initial value) Notes: 1. The TDRE flag in SSR1 is fixed at 1. 2. In this state, serial transmission is started when transmit data is written to TDR1 and the TDRE flag in SSR1 is cleared to 0. SMR1 setting must be performed to decide the transmission format before setting the TE bit to 1. Bit 4: Receive Enable (RE) Enables or disables the start of serial reception by the SCI1. Bit 4 RE 0 1 Description Reception disabled*1 Reception enabled*2 (Initial value) Notes: 1. Clearing the RE bit to 0 does not affect the RDRF, FER, PER, and ORER flags, which retain their states. 2. Serial reception is started in this state when a start bit is detected in asynchronous mode or serial clock input is detected in synchronous mode. SMR1 setting must be performed to decide the reception format before setting the RE bit to 1. Rev. 2.0, 11/00, page 451 of 1037 Bit 3: Multiprocessor Interrupt Enable (MPIE) Enables or disables multiprocessor interrupts. The MPIE bit setting is only valid in asynchronous mode when receiving with the MP bit in SMR1 set to 1. The MPIE bit setting is invalid in clock synchronous mode or when the MP bit is cleared to 0. Bit 3 MPIE 0 Description Multiprocessor interrupts disabled (normal reception performed) [Clearing conditions] (1) When the MPIE bit is cleared to 0 (2) When data with MPB = 1 is received (Initial value) 1 Multiprocessor interrupts enabled* Receive interrupt (RXI) requests, receive-error interrupt (ERI) requests, and setting of the RDRF, FER, and ORER flags in SSR are disabled until data with the multiprocessor bit set to 1 is received. * When receive data including MPB = 0 is received, receive data transfer from RSR to RDR1, receive error detection, and setting of the RDRF, FER, and ORER flags in SSR1, is not performed. When receive data with MPB = 1 is received, the MPB bit in SSR1 is set to 1, the MPIE bit is cleared to 0 automatically, and generation of RXI and ERI interrupts (when the TIE and RIE bits in SCR1 are set to 1) and FER and ORER flag setting is enabled. Note: Bit 2: Transmit End Interrupt Enable (TEIE) Enables or disables transmit-end interrupt (TEI) request generation if there is no valid transmit data in TDR1 when the MSB is transmitted. Bit 2 TEIE 0 1 Note: * Description Transmit-end interrupt (TEI) request disabled* Transmit-end interrupt (TEI) request enabled* TEI cancellation can be performed by reading 1 from the TDRE flag in SSR1, then clearing it to 0 and clearing the TEND flag to 0, or clearing the TEIE bit to 0. (Initial value) Bits 1 and 0: Clock Enable 1 and 0 (CKE1, CKE0) These bits are used to select the SCI1 clock source and enable or disable clock output from the SCK1 pin. The combination of the CKE1 and CKE0 bits determines whether the SCK1 pin functions as an I/O port, the serial clock output pin, or the serial clock input pin. The setting of the CKE0 bit, however, is only valid for internal clock operation (CKE1 = 0) in asynchronous mode. The CKE0 bit setting is invalid in synchronous mode, and in the case of external clock operation (CKE1 = 1). Note that the SCI1's operating mode must be decided using SMR1 before setting the CKE1 and CKE0 bits. For details of clock source selection, see table 23.9 in section 23.3, Operation.

SSR1 is an 8-bit register containing status flags that indicate the operating status of the SCI1, and multiprocessor bits. SSR1 can be read or written to by the CPU at all times. However, 1 cannot be written to flags TDRE, RDRF, ORER, PER, and FER. Also note that in order to clear these flags they must be read as 1 beforehand. The TEND flag and MPB flag are read-only flags and cannot be modified. SSR1 is initialized to H'84 by a reset, and in standby mode, watch mode, subactive mode, subsleep mode, and module stop mode. Rev. 2.0, 11/00, page 453 of 1037 Bit 7: Transmit Data Register Empty (TDRE) Indicates that data has been transferred from TDR1 to TSR and the next serial data can be written to TDR1. Bit 7 TDRE 0 1 Description [Clearing conditions] When 0 is written in TDRE after reading TDRE = 1 [Setting conditions] (Initial value) (1) When the TE bit in SCR1 is 0 (2) When data is transferred from TDR1 to TSR and data can be written to TDR1 Bit 6: Receive Data Register Full (RDRF) Indicates that the received data is stored in RDR1. Bit 6 RDRF 0 1 Description [Clearing conditions] When 0 is written in RDRF after reading RDRF = 1 (Initial value) [Setting conditions] When serial reception ends normally and receive data is transferred from RSR to RDR1 Note: RDR1 and the RDRF flag are not affected and retain their previous values when an error is detected during reception or when the RE bit in SCR1 is cleared to 0. If reception of the next data is completed while the RDRF flag is still set to 1, an overrun error will occur and the receive data will be lost. Rev. 2.0, 11/00, page 454 of 1037 Bit 5: Overrun Error (ORER) Indicates that an overrun error occurred during reception, causing abnormal termination. Bit 5 ORER 0 1 Description [Clearing conditions] When 0 is written in ORER after reading ORER = 1 [Setting conditions] When the next serial reception is completed while RDRF = 1*2 (Initial value)*1 Notes: 1. The ORER flag is not affected and retains its previous state when the RE bit in SCR1 is cleared to 0. 2. The receive data prior to the overrun error is retained in RDR1, and the data received subsequently is lost. Also, subsequent serial reception cannot be continued while the ORER flag is set to 1. In clock synchronous mode, serial transmission cannot be continued, either. Bit 4: Framing Error (FER) Indicates that a framing error occurred during reception in asynchronous mode, causing abnormal termination. Bit 4 FER 0 1 Description [Clearing conditions] When 0 is written in FER after reading FER = 1 (Initial value)*1 [Setting conditions] When the SCI1 checks the stop bit at the end of the receive data when reception ends, and the stop bit is 0*2 Notes: 1. The FER flag is not affected and retains its previous state when the RE bit in SCR1 is cleared to 0. 2. In 2-stop-bit mode, only the first stop bit is checked for a value of 1; the second stop bit is not checked. If a framing error occurs, the receive data is transferred to RDR1 but the RDRF flag is not set. Also, subsequent serial reception cannot be continued while the FER flag is set to 1. In clock synchronous mode, serial transmission cannot be continued, either. Rev. 2.0, 11/00, page 455 of 1037 Bit 3: Parity Error (PER) Indicates that a parity error occurred during reception using parity addition in asynchronous mode, causing abnormal termination. Bit 4 PER 0 1 Description [Clearing conditions] When 0 is written in PER after reading PER = 1 (Initial value)*1 [Setting conditions] When, in reception, the number of 1 bits in the receive data plus the parity bit does not match the parity setting (even or odd) specified by the O/ bit in SMR1*2 Notes: 1. The PER flag is not affected and retains its previous state when the RE bit in SCR1 is cleared to 0. 2. If a parity error occurs, the receive data is transferred to RDR1 but the RDRF flag is not set. Also, subsequent serial reception cannot be continued while the PER flag is set to 1. In clock synchronous mode, serial transmission cannot be continued, either.

Selection of asynchronous or synchronous mode and the transmission format is made using SMR1 as shown in table 23.8. The SCI1 clock is determined by a combination of the C/ bit in SMR1 and the CKE1 and CKE0 bits in SCR1, as shown in table 23.9. (1) Asynchronous Mode * Data length: Choice of 7 or 8 bits * Choice of parity addition, multiprocessor bit addition, and addition of 1 or 2 stop bits (the combination of these parameters determines the transfer format and character length) * Detection of framing, parity, and overrun errors, and breaks, during reception * Choice of internal or external clock as SCI1 clock source -- When internal clock is selected: The SCI1 operates on the baud rate generator clock and a clock with the same frequency as the bit rate can be output -- When external clock is selected: A clock with a frequency of 16 times the bit rate must be input (the built-in baud rate generator is not used) (2) Clock Synchronous Mode * Transfer format: Fixed 8-bit data * Detection of overrun errors during reception * Choice of internal or external clock as SCI1 clock source -- When internal clock is selected: The SCI1 operates on the baud rate generator clock and a serial clock is output offchip -- When external clock is selected: The built-in baud rate generator is not used, and the SCI1 operates on the input serial clock Rev. 2.0, 11/00, page 466 of 1037 Table 23.8 SMR1 Settings and Serial Transfer Format Selection SMR1 Settings Bit 7 C/ 0 Bit 6 CHR 0 Bit 2 MP 0 Bit 5 PE 0 1 1 0 1 0 1 1 1 Bit 3 STOP 0 1 0 1 0 1 0 1 0 1 0 1 Asynchronous mode (multiprocessor format) Clock synchronous mode 8-bit data 7-bit data 8-bit data No Yes No 7-bit data No Yes Mode Asynchronous mode SCI1 Transfer Format Data length 8-bit data Multiproc -essor bit No Parit y bit No Yes Stop bit length 1 bit 2 bits 1 bit 2 bits 1 bit 2 bits 1 bit 2 bits 1 bit 2 bits 1 bit 2 bits Table 23.9 SMR1 and SCR1 Settings and SCI1 Clock Source Selection SMR1 Bit 7 C/ 0 SCR1 Setting Bit 1 CKE1 0 Bit 0 CKE0 0 1 1 1 0 1 0 1 0 1 0 1 Clock synchronous mode Internal External Mode Asynchronous mode SCI1 Transfer Clock Clock Source Internal SCK1 Pin Function SCI1 does not use SCK1 pin Outputs clock with same frequency as bit rate External Inputs clock with frequency of 16 times the bit rate Outputs serial clock Inputs serial clock Rev. 2.0, 11/00, page 467 of 1037 23.3.2 Operation in Asynchronous Mode In asynchronous mode, characters are sent or received, each preceded by a start bit indicating the start of communication and followed by one or two stop bits indicating the end of communication. Serial communication is thus carried out with synchronization established on a character-by-character basis. Inside the SCI1, the transmitter and receiver are independent units, enabling full-duplex communication. Both the transmitter and the receiver also have a double-buffered structure, so that data can be read or written during transmission or reception, enabling continuous data transfer. Figure 23.2 shows the general format for asynchronous serial communication. In asynchronous serial communication, the transmission line is usually held in the mark state (high level). The SCI1 monitors the transmission line, and when it goes to the space state (low level), recognizes a start bit and starts serial communication. One serial communication character consists of a start bit (low level), followed by data (in LSBfirst order), a parity bit (high or low level), and finally one or two stop bits (high level). In asynchronous mode, the SCI1 performs synchronization at the falling edge of the start bit in reception. The SCI1 samples the data on the 8th pulse of a clock with a frequency of 16 times the length of one bit, so that the transfer data is latched at the center of each bit.

For details of SCI1 clock source selection, see table 23.9. When an external clock is input at the SCK1 pin, the clock frequency should be 16 times the bit rate used. When the SCI1 is operated on an internal clock, the clock can be output from the SCK1 pin. The frequency of the clock output in this case is equal to the bit rate, and the phase is such that the rising edge of the clock is at the center of each transmit data bit, as shown in figure 23.3. 0 D0 D1 D2 D3 D4 D5 D6 D7 0/1 1 1 1 frame Figure 23.3 Relation between Output Clock and Transfer Data Phase (Asynchronous Mode) Rev. 2.0, 11/00, page 470 of 1037 (3) Data Transfer Operations (a) SCI1 Initialization (Asynchronous Mode) Before transmitting and receiving data, first clear the TE and RE bits in SCR1 to 0, then initialize the SCI1 as described below. When the operating mode, transfer format, etc., is changed, the TE and RE bits must be cleared to 0 before making the change using the following procedure. When the TE bit is cleared to 0, the TDRE flag is set to 1 and TSR is initialized. Note that clearing the RE bit to 0 does not change the contents of the RDRF, PER, FER, and ORER flags, or the contents of RDR1. When an external clock is used the clock should not be stopped during operation, including initialization, since operation is uncertain. Figure 23.4 shows a sample SCI1 initialization flowchart. Start initialization [1] Set the clock selection in SCR1. Be sure to clear bits RIE, TIE, TEIE, and MPIE, and bits TE and RE, to 0. When the clock is selected in asynchronous mode, it is output immediately after SCR1 settings are made. [1] [2] Set the data transfer format in SMR1 and SCMR1. [3] Write a value corresponding to the bit rate to BRR1. This is not necessary if an external clock is used. [4] Wait at least one bit interval, then set the TE bit or RE bit in SCR1 to 1. Also set the RIE, TIE, TEIE, and MPIE bits. Setting the TE and RE bits enables the SO1 and SI1 pins to be used. Clear TE and RE bits in SCR1 to 0 Set CKE1 and CKE0 bits in SCR1 (TE, RE bits 0) Set data transfer format in SMR1 and SCMR1 Set value in BRR1 Wait [2] [3] No 1-bit interval elapsed? Yes Set TE and RE bits in SCR1 to 1, and set RIE, TIE, TEIE, and MPIE bits [4] Figure 23.4 Sample SCI Initialization Flowchart Rev. 2.0, 11/00, page 471 of 1037 (b) Serial Data Transmission (Asynchronous Mode) Figure 23.5 shows a sample flowchart for serial transmission. The following procedure should be used for serial data transmission. Initialization Start transmission [1] [1] SCI1 initialization: The SO1 pin is automatically designated as the transmit data output pin. [2] SCI1 status check and transmit data write: Read SSR1 and check that the TDRE flag is set to 1, then write transmit data to TDR1 and clear the TDRE flag to 0. [3] Serial transmission continuation procedure: To continue serial transmission, read 1 from the TDRE flag to confirm that writing is possible, then write data to TDR1, and then clear the TDRE flag to 0. [4] Break output at the end of serial transmission: To output a break in serial transmission, set PCR for the port corresponding to the SO1 pin to 1, clear PDR to 0, then clear the TE bit in SCR1 to 0. Read TDRE flag in SSR1 [1] No TDRE=1 Yes Write transmit data to TDR1 and clear TDRE flag in SSR1 to 0 No All data transmitted? Yes [3] Read TEND flag in SSR1 No TEND=1 Yes No Break output? Yes Clear PDR to 0 and set PCR to 1 [4] Clear TE bit in SCR1 to 0 < End > Figure 23.5 Sample Serial Transmission Flowchart Rev. 2.0, 11/00, page 472 of 1037 In serial transmission, the SCI1 operates as described below. [1] The SCI1 monitors the TDRE flag in SSR1, and if it is 0, recognizes that data has been written to TDR1, and transfers the data from TDR1 to TSR. [2] After transferring data from TDR1 to TSR, the SCI1 sets the TDRE flag to 1 and starts transmission. If the TIE bit is set to 1 at this time, a transmit data empty interrupt (TXI) is generated. The serial transmit data is sent from the SO1 pin in the following order. [a] Start bit: One 0-bit is output. [b] Transmit data: 8-bit or 7-bit data is output in LSB-first order. [c] Parity bit or multiprocessor bit: One parity bit (even or odd parity), or one multiprocessor bit is output. A format in which neither a parity bit nor a multiprocessor bit is output can also be selected. [d] Stop bit(s): One or two 1-bits (stop bits) are output. [e] Mark state: 1 is output continuously until the start bit that starts the next transmission is sent. [3] The SCI1 checks the TDRE flag at the timing for sending the stop bit. If the TDRE flag is cleared to 0, the data is transferred from TDR1 to TSR, the stop bit is sent, and then serial transmission of the next frame is started. If the TDRE flag is set to 1, the TEND flag in SSR1 is set to 1, the stop bit is sent, and then the mark state is entered in which 1 is output continuously. If the TEIE bit in SCR1 is set to 1 at this time, a TEI interrupt request is generated. Figure 23.6 shows an example of the operation for transmission in asynchronous mode.

The following procedure should be used for serial data reception. Initialization Start reception [1] [1] SCI1 initialization: The SI1 pin is automatically designated as the receive data input pin. [2][3] Receive error handling and break detection: If a receive error occurs, read the ORER, PER, and FER flags in SSR1 to identify the error. After performing the appropriate error handling, ensure that the ORER, PER, and FER flags are all cleared to 0. Reception cannot be resumed if any of these flags are set to 1. In the case of a framing error, a break can be detected by reading the value of the input port corresponding to the SI1 pin.

Transition of the RDRF flag from 0 to 1 can also be identified by an RXI interrupt.

[1] The SCI1 monitors the transmission line, and if a 0 stop bit is detected, performs internal synchronization and starts reception. [2] The received data is stored in RSR in LSB-to-MSB order. [3] The parity bit and stop bit are received. After receiving these bits, the SCI1 carries out the following checks. [a] Parity check: The SCI1 checks whether the number of 1 bits in the receive data agrees with the parity (even or odd) set in the O/ bit in SMR1. [b] Stop bit check: The SCI1 checks whether the stop bit is 1. If there are two stop bits, only the first is checked. [c] Status check: The SCI1 checks whether the RDRF flag is 0, indicating that the receive data can be transferred from RSR to RDR1. If all the above checks are passed, the RDRF flag is set to 1, and the receive data is stored in RDR1. If a receive error* is detected in the error check, the operation is as shown in table 23.11. Note: * Subsequent receive operations cannot be performed when a receive error has occurred. Also note that the RDRF flag is not set to 1 in reception, and so the error flags must be cleared to 0. [4] If the RIE bit in SCR1 is set to 1 when the RDRF flag changes to 1, a receive-data-full interrupt (RXI) request is generated. Also, if the RIE bit in SCR1 is set to 1 when the ORER, PER, or FER flag changes to 1, a receive-error interrupt (ERI) request is generated.

Use of this function enables data transfer to be performed among a number of processors sharing transmission lines. When multiprocessor communication is carried out, each receiving station is addressed by a unique ID code. The serial communication cycle consists of two component cycles: an ID transmission cycle which specifies the receiving station, and a data transmission cycle. The multiprocessor bit is used to differentiate between the ID transmission cycle and the data transmission cycle. The transmitting station first sends the ID of the receiving station with which it wants to perform serial communication as data with a 1 multiprocessor bit added. It then sends transmit data as data with a 0 multiprocessor bit added. The receiving station skips the data until data with a 1 multiprocessor bit is sent. When data with a 1 multiprocessor bit is received, the receiving station compares that data with its own ID. The station whose ID matches then receives the data sent next. Stations whose ID does not match continue to skip the data until data with a 1 multiprocessor bit is again received. In this way, data communication is carried out among a number of processors. Figure 23.9 shows an example of inter-processor communication using a multiprocessor format. Rev. 2.0, 11/00, page 478 of 1037 (1) Data Transfer Format There are four data transfer formats. When a multiprocessor format is specified, the parity bit specification is invalid. For details, see table 23.10. (2) Clock See the section on asynchronous mode.

[2] SCI1 status check and transmit data write: Read SSR1 and check that the TDRE flag is set to 1, then write transmit data to TDR1. Set the MPBT bit in SSR1 to 0 or 1. Finally, clear the TDRE flag to 0. [3] Serial transmission continuation procedure: To continue serial transmission, be sure to read 1 from the TDRE flag to confirm that writing is possible, then write data to TDR1, and then clear the TDRE flag to 0. [4] Break output at the end of serial transmission: To output a break in serial transmission, set the port PCR to 1, clear PDR to 0, then clear the TE bit in SCR1 to 0.

[1] The SCI1 monitors the TDRE flag in SSR1, and if it is 0, recognizes that data has been written to TDR1, and transfers the data from TDR1 to TSR. [2] After transferring data from TDR1 to TSR, the SCI1 sets the TDRE flag to 1 and starts transmission. If the TIE bit is set to 1 at this time, a transmit-data-empty interrupt (TXI) is generated. The serial transmit data is sent from the SO2 pin in the following order. [a] Start bit: One 0-bit is output. [b] Transmit data: 8-bit or 7-bit data is output in LSB-first order. [c] Multiprocessor bit One multiprocessor bit (MPBT value) is output. [d] Stop bit(s): One or two 1-bits (stop bits) are output. [e] Mark state: 1 is output continuously until the start bit that starts the next transmission is sent. [3] The SCI1 checks the TDRE flag at the timing for sending the stop bit. If the TDRE flag is cleared to 0, data is transferred from TDR1 to TSR, the stop bit is sent, and then serial transmission of the next frame is started. If the TDRE flag is set to 1, the TEND flag in SSR1 is set to 1, the stop bit is sent, and then the mark state is entered in which 1 is output continuously. If the TEIE bit in SCR1 is set to 1 at this time, a transmit-end interrupt (TEI) request is generated.

[5] Receive error handling and break detectioon: If a receive error occurs, read the ORER and FER flags in SSR1 to identify the error. After performing the appropriate error handling, ensure that the ORER and FER flags are both cleared to 0. Reception cannot be resumed if either of these flags is set to 1. In the case of a framing error, a break can be detected by reading the SI1 in value.

Inside the SCI1, the transmitter and receiver are independent units, enabling full-duplex communication by use of a common clock. Both the transmitter and the receiver also have a double-buffered structure, so that data can be read or written during transmission or reception, enabling continuous data transfer. Figure 23.14 shows the general format for clock synchronous serial communication. One unit of transfer data (character or frame) * Synchronous clock LSB Serial data Don't care Note: * High except in continuous transmit/reception Bit 0 Bit 1 Bit 2 Bit 3 Bit 4 Bit 5 Bit 6 MSB Bit 7 Don't care * Figure 23.14 Data Format in Clock Synchronous Communication In clock synchronous serial communication, data on the transmission line is output from one falling edge of the serial clock to the next. Data is guaranteed valid at the rising edge of the serial clock. In clock synchronous serial communication, one character consists of data output starting with the LSB and ending with the MSB. After the MSB is output, the transmission line holds the MSB state. In clock synchronous mode, the SCI1 receives data in synchronization with the rising edge of the serial clock. (1) Data Transfer Format A fixed 8-bit data format is used. No parity or multiprocessor bits are added. (2) Clock Either an internal clock generated by the built-in baud rate generator or an external serial clock input at the SCK1 pin can be selected, according to the setting of the C/ bit in SMR1 and the CKE1 and CKE0 bits in SCR1. For details on SCI clock source selection, see table 23.9. When the SCI1 is operated on an internal clock, the serial clock is output from the SCK1 pin. Rev. 2.0, 11/00, page 486 of 1037 Eight serial clock pulses are output in the transfer of one character, and when no transfer is performed the clock is fixed high. When only receive operations are performed, however, the serial clock is output until an overrun error occurs or the RE bit is cleared to 0. To perform receive operations in units of one character, select an external clock as the clock source. (3) Data Transfer Operations (a) SCI1 Initialization (Synchronous Mode) Before transmitting and receiving data, first clear the TE and RE bits in SCR1 to 0, then initialize the SCI1 as described below. When the operating mode, transfer format, etc., is changed, the TE and RE bits must be cleared to 0 before making the change using the following procedure. When the TE bit is cleared to 0, the TDRE flag is set to 1 and TSR is initialized. Note that clearing the RE bit to 0 does not change the settings of the RDRF, PER, FER, and ORER flags, or the contents of RDR1. Figure 23.15 shows a sample SCI1 initialization flowchart. Start initialization [1] Set the clock selection in SCR1. Be sure to clear bits RIE, TIE, TEIE, and MPIE, TE and RE, to 0. [2] Set the data transfer format in SMR1 and SCMR1. [1] [3] Write a value corresponding to the bit rate to BRR1. This is not necessary if an external clock is used. [4] Wait at least one bit interval, then set the TE bit or RE bit in SCR1 to 1. Also set the RIE, TIE, TEIE, and MPIE bits. Setting the TE and RE bits enables the SO1 and SI1 pins to be used. Clear TE and RE bits in SCR1 to 0 Set CKE1 and CKE0 bits in SCR1 (TE, RE bits 0) Set data transfer format in SMR1 and SCMR1 Set value in BRR1 Wait [2] [3] No 1-bit interval elapsed?

[1] The SCI1 monitors the TDRE flag in SSR1, and if it is 0, recognizes that data has been written to TDR1, and transfers the data from TDR1 to TSR. [2] After transferring data from TDR1 to TSR, the SCI1 sets the TDRE flag to 1 and starts transmission. If the TIE bit is set to 1 at this time, a transmit-data-empty interrupt (TXI) is generated. When clock output mode has been set, the SCI1 outputs 8 serial clock pulses. When use of an external clock has been specified, data is output synchronized with the input clock. The serial transmit data is sent from the SO1 pin starting with the LSB (bit 0) and ending with the MSB (bit 7). [3] The SCI1 checks the TDRE flag at the timing for sending the MSB (bit 7). If the TDRE flag is cleared to 0, data is transferred from TDR1 to TSR, and serial transmission of the next frame is started. If the TDRE flag is set to 1, the TEND flag in SSR1 is set to 1, the MSB (bit 7) is sent, and the SO1 pin maintains its state. If the TEIE bit in SCR1 is set to 1 at this time, a transmit-end interrupt (TEI) request is generated. [4] After completion of serial transmission, the SCK1 pin is held in a constant state. Figure 23.17 shows an example of SCI1 operation in transmission.

The following procedure should be used for serial data reception. When changing the operating mode from asynchronous to synchronous, be sure to check that the ORER, PER, and FER flags are all cleared to 0. The RDRF flag will not be set if the FER or PER flag is set to 1, and neither transmit nor receive operations will be possible.

[1] The SCI1 performs internal initialization in synchronization with serial clock input or output. [2] The received data is stored in RSR in LSB-to-MSB order. After reception, the SCI1 checks whether the RDRF flag is 0 and the receive data can be transferred from RSR to RDR1. If this check is passed, the RDRF flag is set to 1, and the receive data is stored in RDR1. If a receive error is detected in the error check, the operation is as shown in table 23.11. Neither transmit nor receive operations can be performed subsequently when a receive error has been found in the error check. [3] If the RIE bit in SCR1 is set to 1 when the RDRF flag changes to 1, a receive-data-full interrupt (RXI) request is generated. Also, if the RIE bit in SCR1 is set to 1 when the ORER flag changes to 1, a receive-error interrupt (ERI) request is generated. Figure 23.19 shows an example of SCI1 operation in reception.

Transition of the TDRE flag from 0 to 1 can also be identified by a TXI interrupt. [3] Receive error handling: If a receive error occurs, read the ORER flag in SSR1, and after performing the appropriate error handling, clear the ORER flag to 0. Transmission/reception cannot be resumed if the ORER flag is set to 1.

Figure 23.20 Sample Flowchart of Simultaneous Serial Transmit and Receive Operations Rev. 2.0, 11/00, page 493 of 1037 23.4 SCI1 Interrupts The SCI1 has four interrupt sources: the transmit-end interrupt (TEI) request, receive-error interrupt (ERI) request, receive-data-full interrupt (RXI) request, and transmit-data-empty interrupt (TXI) request. Table 23.13 shows the interrupt sources and their relative priorities. Individual interrupt sources can be enabled or disabled with the TIE, RIE, and TEIE bits in SCR1. Each kind of interrupt request is sent to the interrupt controller independently. When the TDRE flag in SSR1 is set to 1, a TXI interrupt request is generated. When the TEND flag in SSR1 is set to 1, a TEI interrupt request is generated. When the RDRF flag in SSR1 is set to 1, an RXI interrupt request is generated. When the ORER, PER, or FER flag in SSR1 is set to 1, an ERI interrupt request is generated. Table 23.13 SCI1 Interrupt Sources Channel 1 Interrupt Source ERI RXI TXI TEI Description Interrupt by receive error (ORER, FER, or PER) Interrupt by receive data register full (RDRF) Interrupt by transmit data register empty (TDRE) Interrupt by transmit end (TEND) Low Priority* High The TEI interrupt is requested when the TEND flag is set to 1 while the TEIE bit is set to 1. The TEND flag is cleared at the same time as the TDRE flag. Consequently, if a TEI interrupt and a TXI interrupt are requested simultaneously, the TXI interrupt will have priority for acceptance, and the TDRE flag and TEND flag may be cleared. Note that the TEI interrupt will not be accepted in this case. Rev. 2.0, 11/00, page 494 of 1037 23.5 Usage Notes The following points should be noted when using the SCI1. (1) Relation between Writes to TDR1 and the TDRE Flag The TDRE flag in SSR1 is a status flag that indicates that transmit data has been transferred from TDR1 to TSR. When the SCI transfers data from TDR1 to TSR, the TDRE flag is set to 1. Data can be written to TDR1 regardless of the state of the TDRE flag. However, if new data is written to TDR1 when the TDRE flag is cleared to 0, the data stored in TDR1 will be lost since it has not yet been transferred to TSR. It is therefore essential to check that the TDRE flag is set to 1 before writing transmit data to TDR1. (2) Operation when Multiple Receive Errors Occur Simultaneously If a number of receive errors occur at the same time, the state of the status flags in SSR1 is as shown in table 23.14. If there is an overrun error, data is not transferred from RSR to RDR1, and the receive data is lost. Table 23.14 State of SSR1 Status Flags and Transfer of Receive Data SSR1 Status Flags RDRF 1 0 0 1 1 0 1 Notes: ORER 1 0 0 1 1 0 1 FER 0 1 0 1 0 1 1 PER 0 0 1 0 1 1 1 Receive Data Transfer RSR RDR1 x Receive Errors Overrun error Framing error Parity error Overrun error + framing error Overrun error + parity error Framing error + parity error { { x x x { {: Receive data is transferred from RSR to RDR1. Overrun error + framing error + parity error x: Receive data is not transferred from RSR to RDR1. (3) Break Detection and Processing When a framing error (FER) is detected, a break can be detected by reading the SI1 pin value directly. In a break, the input from the SI1 pin becomes all 0s, and so the FER flag is set, and the parity error flag (PER) may also be set. Note that, since the SCI1 continues the receive operation after receiving a break, even if the FER flag is cleared to 0, it will be set to 1 again. (4) Sending a Break The SO1 pin has a dual function as an I/O port whose direction (input or output) is determined by PDR and PCR. This feature can be used to send a break. Rev. 2.0, 11/00, page 495 of 1037 Between serial transmission initialization and setting of the TE bit to 1, the mark state is replaced by the value of PDR (the pin does not function as the SO1 pin until the TE bit is set to 1). Consequently, PCR and PDR for the port corresponding to the SO1 pin should first be set to 1. To send a break during serial transmission, first clear PDR to 0, then clear the TE bit to 0. When the TE bit is cleared to 0, the transmitter is initialized regardless of the current transmission state, the SO1 pin becomes an I/O port, and 0 is output from the SO1 pin. (5) Receive Error Flags and Transmit Operations (Clock Synchronous Mode Only) Transmission cannot be started when a receive error flag (ORER, PER, or FER) is set to 1, even if the TDRE flag is cleared to 0. Be sure to clear the receive error flags to 0 before starting transmission. Note also that receive error flags cannot be cleared to 0 even if the RE bit is cleared to 0. (6) Receive Data Sampling Timing and Reception Margin in Asynchronous Mode In asynchronous mode, the SCI1 operates on a base clock with a frequency of 16 times the transfer rate. In reception, the SCI1 samples the falling edge of the start bit using the base clock, and performs internal synchronization. Receive data is latched internally at the rising edge of the 8th pulse of the base clock.

The 5 loworder bits of the STAR correspond to the 5 low-order bits of the address of 32-byte buffer. The range for executing continuous data transfer on STAR and EDAR is specified. When the value of STAR is equal to that of EDAR, only one-byte transfer is carried out. Since the 7 to 5 bits of the STAR are reserved, writes are disabled. When each bit is read, 1 is read at all times. The STAR is initialized to H'E0 by a reset. 24.2.2 Ending Address Register (EDAR) Bit : Initial value : R/W : 7 -- 1 -- 6 -- 1 -- 5 -- 1 -- 4 EDA4 0 R/W 3 EDA3 0 R/W 2 EDA2 0 R/W 1 EDA1 0 R/W 0 EDA0 0 R/W The EDAR is a readable/writable register that specifies the transfer ending address within the address space (H'FFD0C0 to H'FFD0DF) to which 32-byte data buffer is assigned. The 5 loworder bits of EDAR correspond to the 5 low-order bits of the address of 32-byte buffer. The range for executing continuous data transfer is specified by the EDAR and the STAR. If the value of the STAR is equal to that of the EDAR, only one-byte transfer is carried out. Since the 7 to 5 bits of the EDAR are reserved, writes are disabled. When each bit is read, 1 is read at all times. The EDAR is initialized to H'E0 by a reset. Rev. 2.0, 11/00, page 502 of 1037 24.2.3 Serial Control Register 2 (SCR2) Bit : 7 TEIE 0 R/W 6 ABTIE 0 R/W 5 -- 1 -- 4 GAP1 0 R/W 3 GAP0 0 R/W 2 CKS2 0 R/W 1 CKS1 0 R/W 0 CKS0 0 R/W Initial value : R/W : The SCR 2 is a readable/writable register that enables or disables generation of SCI2 interrupt and selects an data transfer interval and transfer clock when an internal clock is used. The SCR2 is initialized to H'20 by a reset. Bit 7: Transmit End Interrupt Enable (TEIE) Enables or disables the occurrence of transmit-end interrupt when data transfer has been completed and TEI of the SCR2 has been set to 1. Bit 7 TEIE 0 1 Description Transmit-end interrupt disabled Transmit-end interrupt enabled (Initial value) Bit 6: Transmit Cutoff Interrupt (ABTIE) Enables or disables the occurrence of transmit-cutoff interrupt when the $ pin has entered a high level during transmission and ABT of the SCRS2 has been set to 1. Bit 6 ABTIE 0 1 Description Transmit-cutoff interrupt disabled Transmit-cutoff interrupt enabled (Initial value) Bit 5: Reserved When read, 1 is read at all times. Writes are disabled. Rev. 2.0, 11/00, page 503 of 1037 Bits 4 and 3: Transmit Data Interval Select 1 and 0 (GAP1, GAP0) When an internal clock is used, data can be transmitted at 1-byte intervals. During that time, the SCK2 pin retains the high level. When data is transmitted without intervals, the STRB signal retains the low level.

The SCSR2 is an 8-bit register that indicates the SCI2's state of operation and error. The SCSR2 is initialized to H'60 by a reset. Rev. 2.0, 11/00, page 504 of 1037 Bit 7: Transmit End Interrupt Request Flag (TEI) Indicates that data transmission or reception has been completed. Bit 7 TEI 0 1 Description [Clearing condition] When 0 is written after reading 1 [Setting condition] When transmission or reception has been completed (Initial value) Bits 6 and 5: Reserved When each bit is read, 1 is read at all times. Writes are disabled. Bit 4: Extension Data Bit (SOL) The SOL sets the output level of the SO2 pin. When read, the output level of the SO2 pin is read. Output of the SO2 pin after completion of transmission retains the value of final bit of transfer data, but the output level of the SO2 pin can be changed by operating this bit before or after transmission. However, setting of the SOL bit becomes invalid when the next transmission is started. Therefore, if the output level of the SO2 pin is changed after completion of transmission, write operation for SOL must be performed every time when transmission is terminated. Since writing to this register during data transfer may cause malfunction, write operation must not be performed during transmission. Bit 4 SOL 0 1 Description Read Write Read Write The SO2 pin output is at a low level The SO2 pin output is changed to a low level The SO2 pin output is at a high level The SO2 pin output is changed to a high level (Initial value) Rev. 2.0, 11/00, page 505 of 1037 Bit 3: Overrun Error Flag (ORER) The ORER indicates an occurrence of overrun error while an external clock is used. When excessive pulses are overlapped with the normal transfer clock caused by external noise, etc. during transmission, this bit is set to 1. At this time data transfer cannot be assured. When a clock is input after completion of transmission, it is also found to be in the state of overrun and this bit is set to 1. However, overrun is not detected when the $ pin is at a high level. Bit 3 ORER 0 1 Description [Clearing condition] When 0 is written after reading 1 (Initial value) [Setting condition] When excessive pulses are overlapped with a normal transfer clock while an external clock is used, or when a clock is input after completion of transmission Bit 2: Wait Flag (WT) The WT indicates that read/ or write to serial data buffer (32 bytes) has been executed during transmission and in the $ input standby mode. The instruction at that time is ignored and this bit is set to 1. Bit 2 WT 0 1 Description [Clearing condition] When 0 is written after reading 1 (Initial value) [Setting condition] When an instruction to read/write to serial data buffer (32 bits) is directed during transmission and in the $ input standby mode Bit 1: Abort Flag (ABT) The ABT indicates that the $ pin has entered a high level during transmission. When a high level of the $ pin is detected during transfer, the transfer is immediately cut off, and this bit is set to 1, and then the SCK2 and SO2 pins go into the high impedance state. At this time values of internal registers other than SCSR2 and serial data buffer (32 bytes) are retained. Transfer cannot be carried out while this bit is set to 0. Resume transfer after clearing to 0. Bit 1 ABT 0 1 Description [Clearing condition] When 0 is written after reading 1 [Setting condition] During transfer and when $ pin has entered a high level (Initial value) Rev. 2.0, 11/00, page 506 of 1037 Bit 0: Start Flag (STF) The STF controls the start of transfer operations. When this bit is set to 1 and PMR30 of PMR3 is 0, transfer operation of the SCI2 is started. When PMR30 of PMR3 is 1, the low level of the $ pin is detected and transfer is started. This bit retains 1 during transfer and in the $ input standby mode, and it is cleared to 0 after completion of transfer and when transfer is cut off by the $ pin. Therefore, this bit can be used as a busy flag. When this bit is cleared to 0 during transfer, the transfer is cut off and the SCI2 is initialized. At this time the contents of internal registers other than the SCR2 and the serial data buffer (32 bytes) are retained. Bit 0 STF 0 1 Description Read Write Read Write Transfer operations stops During transfer operation or in $ input standby mode Transfer operation starts (Initial value) Transfer operation discontinues and the SCI2 is initialized 24.2.5 Module Stop Control Register (MSTPCR) MSTPCRH Bit : 7 1 6 1 5 1 4 1 3 1 2 1 1 1 0 1 7 1 6 1 5 1 MSTPCRL 4 1 3 1 2 1 1 1 0 1 MSTP15 MSTP14 MSTP13 MSTP12 MSTP11 MSTP10 MSTP9 MSTP8 MSTP7 MSTP6 MSTP5 MSTP4 MSTP3 MSTP2 MSTP1 MSTP0 Initial value : R/W : R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W The MSTPCR, comprising two 8-bit readable/writable registers, performs module stop mode control. When the MSTPCR is set to 1, the SCI2 stops at the end of bus cycle and a transition is made to the module stop mode. For details, see section 4.5 Module Stop Mode. The MSTPCR is initialized to H'FFFF by a reset. Bit 7: Module Stop (MSTP7) Specifies the SCI2 module stop mode. MSTPCRL Bit 7 MSTP7 0 1 Description SCI2 module stop mode is cleared SCI2 module stop mode is set (Initial value) Rev. 2.0, 11/00, page 507 of 1037 24.3 Operation The SCI2, comprising 32 bytes serial data buffer, can continuously transmit a maximum of 32 bytes data by a single operation, synchronized with clock pulse. Installation of a register enables to select transmit, receive, or simultaneous transmit/receive. When transmit is set, the value of serial data buffer is retained even after completion of transmission. An internal or external clock can be selected as transfer clock. When an internal clock is selected, data can be transmitted at 1-byte intervals. The strobe signal can also be output from the STRB pin. When an external clock is selected, malfunction due to clock can be detected by the overrun flag. The start of transfer and its forced cutoff can be controlled by $ input. Forced cutoff can be detected by the abort flag. 24.3.1 Clock Selection of a transfer clock can be made from seven internal clocks and an external clock. When an internal clock is selected, the SCK2 pin becomes a clock output pin. 24.3.2 Data Transfer Format Figures 24.2 and 24.3 show transfer format of the SCI2. LSB-first transfer that allows to transmit/receive from the lowest-order bit of data is performed. Transmit data is output from the fall of the transfer clock to its next fall. Receive data is collected at the rise of the transfer clock. When an internal clock is selected as a transfer clock, data can be transferred at intervals of 1 byte. The SCK2 output is retained at a high level between transfer data. The strobe signal can be output from the STRB pin. Selection of interval of transfer data is set at GAP1 or GAP0.

Initialization is performed as described below: (1) Use PMR2, PMR3, STAR, EDAR and SCR2 to set the pin and transmission mode while STF of SCSR2 is set to 0. (2) The SCI2 pin is also used as a port. Switching of a port is performed on PMR. The SO2 pin allows to select CMOS output or NMOS open drain output on PMR2. Transfer clock and transfer data intervals can be set on SCR2. (3) The starting and ending addresses in the transfer data area are set on STAR and EDAR. If the value of the ending address is smaller than that of the starting address, transfer data at H'FFD0DF and then return to H'FFD0C0 so that transfer to the ending address can be carried out as shows in figure 24.4. If the value of the starting address is equal to that of the ending address is equal, perform one-byte transfer. H' FFD0C0 End Ending address Start Starting address H' FFD0DF Figure 24.4 If The Value of The Ending Address is Smaller Than That of The Starting Address Rev. 2.0, 11/00, page 511 of 1037 (2) Transmit Operations Transmit operations are performed as described below: (1) Set PMR26 and PMR27 of PMR2 to 1 and set them to the SO2 and SCK2 pins, respectively. Set the SO2 pin to the open drain output using PMR20 of PMR2 and set them to the $ and STRB pins, respectively, using PMR30 and PMR31 of PMR3, as necessary. (2) Set the transfer clock and transfer data intervals (only when an internal clock is in operation) by setting SCR2. (3) Write transmit data to serial data buffer. In transmit operations, the contents of the data buffer will be retained even after the end of transmission. When the same data is transmitted again, it is not necessary to write data. (4) Set STAR to the 5 low-order bits at the transmission starting address and EDAR to the 5 low-order bits at the transmission ending address. (5) Set STF to 1. When PMR30 of PMR3 is set to 0, transmission is started by setting STF. While PMR30 of PMR3 is set to 1, transmission is started when low level of the $ pin is detected. (6) After completion of transmission, TEI of SCSR2 is set to 1. STF is cleared to 0. When an internal clock is selected, synchronous clock is output from the SCK2 pin at the time of starting transmission. When transmission has been completed, synchronous clock is not output until the next STF is set. During that time, the SO2 pin continues to output the value of final bit of the immediately preceding data. When an external clock is selected, data is transmitted, synchronized with the clock input from the SCK2 pin. If the synchronous clock is continuously input after completion of transmission, no transmission is performed as the overrun state has been found and then ORER of the SCSR2 is set to 1. The SO2 pin continues to retain the value of final bit of the preceding data. However, if the $ of PMR3 is set to 1, overrun is not detected when the $ pin is at a high level. The output value of the SO2 pin while transmission is being stopped can be changed by SOL of SCSR2. Data buffer cannot be read or written from CPU during transmission or in the $ standby mode. When a Read instruction has been executed, H'FF is read. Even if a Write instruction is executed, buffer does not change. When a Read/Write instruction has been executed during transmission or in the $ input standby mode, WT of the SCSR2 is set. While PMR30 of PMR3 is set to 0, transmission is immediately cut off when a high level of the $ pin has been detected during transmission, and ABT is set to 1, and then STF is cleared to 0. The SCK2 and SO2 pins enter the high impedance state. Therefore, note that transmission may not be carried out while ABT is set to 1, and thus transmission must be resumed after clearing to 0. Rev. 2.0, 11/00, page 512 of 1037 (3) Receive Operations Receive operations are performed as described below: (1) Set PMR25 and PMR27 of PMR2 to 1 and set them to the SI2 and SCK2 pins, respectively. Set them to the $ pin, using PMR30 of PMR3 as necessary. (2) Set the transfer clock and transfer data intervals (only when an internal clock is in operation) by setting SCR2. (3) Set STAR to 5 low-order bits at the receive starting address and EDAR to 5 low-order bits at the receive ending address. This enables to determine the area in the serial data buffer where receive data is stored. (4) Set STF to 1. When PMR30 of PMR3 is set to 0, reception is started by setting STF. While PMR30 of PMR3 is set to 1, reception is started when low level of the $ pin is detected. (5) After completion of reception, TEI of SCSR2 is set to 1. STF is cleared to 0. (6) Read the receive data stored from the serial data buffer. When an internal clock is selected, synchronous clock is output from the SCK2 pin at the time of starting reception. When reception has been completed, synchronous clock is not output until the next STF is set. When an external clock is selected, data is received, synchronized with the clock input from the SCK2 pin. If the synchronous clock is continuously input after completion of reception, no reception is performed as the overrun state has been found and then ORER of the SCSR2 is set to 1. However, if the $ of PMR3 is set to 1, overrun is not detected when the $ pin is at a high level. Data buffer cannot be read or written from CPU during reception or in the $ standby mode. When a Read instruction has been executed, H'FF is read. Even if a Write instruction is executed, buffer does not change. When a Read/Write instruction has been executed during reception or in the $ input standby mode, WT of the SCSR2 is set. While $ of PMR3 is set to 1, transmission is immediately cut off when a high level of the $ pin has been detected during transmission, and ABT is set to 1, and then STF is cleared to 0. The SCK2 and SO2 pins enter the high impedance state. Therefore, note that transmission may not be carried out while ABT is set to 1, and thus transmission must be resumed after clearing to 0. Rev. 2.0, 11/00, page 513 of 1037 (4) Simultaneous Transmit/Receive Operations Simultaneous transmit/receive operations are performed as described below: (1) Set PMR25, PMR26 and PMR27 of PMR2 to 1 and set them to the SI2, SO2 and SCK2 pins, respectively. Set the SO2 pin to open drain output, using PMR20 of PMR2, and set them to the $ and STRB pins, respectively, using PMR30 and PMR31, as necessary. (2) Set the transfer clock and transfer data intervals (only when an internal clock is in operation) by setting SCR2. (3) Write transmit data to serial data buffer. In the simultaneous transmit/receive operations, the receive data is stored in the same address alternately with the transmit data. (4) Set STAR to 5 low-order bits at the transmission starting address and EDAR to 5 loworder bits at the transmission ending address. (5) Set STF to 1. When PMR30 of PMR3 is set to 0, transmission is started by setting STF. While PMR30 of PMR3 is set to 1, transmission is started when low level of the $ pin is detected. (6) After completion of transmission, TEI of SCSR2 is set to 1. STF is cleared to 0. (7) Read the receive data stored from the serial data buffer. When an internal clock is selected, synchronous clock is output from the SCK2 pin at the time of starting transmission. When transmission has been completed, synchronous clock is not output until the next STF is set. During that time, the SO2 pin continues to output the value of final bit of the preceding data. When an external clock is selected, data is transmitted, synchronized with the clock input from the SCK2 pin. If the synchronous clock is continuously input after completion of transmission, no transmission is performed as the overrun state has been found and then ORER of the SCSR2 is set to 1. The SO2 pin continues to retain the value of final bit of the preceding data. However, if the CS of PMR3 is set to 1, overrun is not detected when the $ pin is at a high level. The output value of the SO2 pin while transmission is being stopped can be changed by SOL of SCSR2. Data buffer cannot be read or written from CPU during transmission or in the $ standby mode. When a Read instruction has been executed, H'FF is read. Even if a Write instruction is executed, buffer does not change. When a Read/Write instruction has been executed during transmission or in the $ input standby mode, WT of the SCSR2 is set. While the CS of PMR3 is set to 1, transmission is immediately cut off when a high level of the $ pin has been detected during transmission, and ABT is set to 1, and then STF is cleared to 0. The SCK2 and SO2 pins enter the high impedance state. Therefore, note that transmission may not be carried out while ABT is set to 1, and thus transmission must be resumed after clearing to 0. Rev. 2.0, 11/00, page 514 of 1037 24.4 Interrupt Sources An interrupt source of the SCI2 is transmission cutoff by completion of transmission and the $ pin, to which different vector addresses are assigned. On completion of data transfer, TEI of SCSR2 is set to 1, and transfer-end interrupt request is generated. This interrupt can specify enable/disable by setting TEIE of SCR2. While PMR30 of PMR3 is set to 1, transfer is cut off when the $ pin enters a high level during data transfer, and ABT of SCSR2 is set to 1 and then transfer cutoff interrupt request is generated. This interrupt can specify enable/disable by setting ABTIE of SCR2. In the case of transfer cutoff by the $ pin, overrun error, and read/write to serial data buffer during transfer and in the $ standby mode, ABT, ORER, and WT of the SCSR2 is set to 1, respectively. These bits allow to determine error factors. Rev. 2.0, 11/00, page 515 of 1037 Rev. 2.0, 11/00, page 516 of 1037 Section 25 I2C Bus Interface (IIC) 25.1 Overview The I2C bus interface conforms to and provides a subset of the Philips I2C bus (inter-IC bus) interface functions. The register configuration that controls the I2C bus differs partly from the Philips configuration, however. Each I2C bus interface channel uses only one data line (SDA) and one clock line (SCL) to transfer data, saving board and connector space. 25.1.1 Features * Selection of addressing format or non-addressing format -- I2C bus format: addressing format with acknowledge bit, for master/slave operation -- Serial format: non-addressing format without acknowledge bit, for master operation only 2 2 * Conforms to Philips I C bus interface (I C bus format) 2 * Two ways of setting slave address (I C bus format) 2 * Start and stop conditions generated automatically in master mode (I C bus format) 2 * Selection of acknowledge output levels when receiving (I C bus format) 2 * Automatic loading of acknowledge bit when transmitting (I C bus format) 2 * Wait function in master mode (I C bus format) -- A wait can be inserted by driving the SCL pin low after data transfer, excluding acknowledgement. The wait can be cleared by clearing the interrupt flag. 2 * Wait function in slave mode (I C bus format) -- A wait request can be generated by driving the SCL pin low after data transfer, excluding acknowledgement. The wait request is cleared when the next transfer becomes possible. * Three interrupt sources -- Data transfer end (including transmission mode transition with I2C bus format and address reception after loss of master arbitration) -- Address match: when any slave address matches or the general call address is received in slave receive mode (I2C bus format) -- Stop condition detection * Selection of 16 internal clocks (in master mode) * Direct bus drive (with SCL and SDA pins) -- Two pins-P24/SCL and P23/SDA- (normally CMOS pins) function as NMOS-only outputs when the bus drive function is selected. Rev. 2.0, 11/00, page 517 of 1037 25.1.2 Block Diagram 2 Figure 25.1 shows a block diagram of the I C bus interface. Figure 25.2 shows an example of I/O pin connections to external circuits. I/O pins are driven only by NMOS and apparently function as NMOS open-drain outputs. However, applicable voltages to input pins depend on the power (Vcc) voltage of this LSI.

ICDR is divided internally into a shift register (ICDRS), receive buffer (ICDRR), and transmit buffer (ICDRT). ICDRS cannot be read or written by the CPU, ICDRR is read-only, and ICDRT is write-only. Data transfers among the three registers are performed automatically in coordination with changes in the bus state, and affect the status of internal flags such as TDRE and RDRF. 2 After transmission/reception of one frame of data using ICDRS, if the I C bus is in transmit mode and the next data is in ICDRT (the TDRE flag is 0), data is transferred automatically from 2 ICDRT to ICDRS. After transmission/reception of one frame of data using ICDRS, if the I C bus is in receive mode and no previous data remains in ICDRR (the RDRF flag is 0), data is transferred automatically from ICDRS to ICDRR. Rev. 2.0, 11/00, page 522 of 1037 If the number of bits in a frame, excluding the acknowledge bit, is less than 8, transmit data and receive data are stored differently. Transmit data should be written justified toward the MSB side when MLS = 0, and toward the LSB side when MLS = 1. Receive data bits read from the LSB side should be treated as valid when MLS = 0, and bits read from the MSB side when MLS = 1. ICDR is assigned to the same address as SARX, and can be written and read only when the ICE bit is set to 1 in ICCR. The value of ICDR is undefined after a reset. The TDRE and RDRF flags are set and cleared under the conditions shown below. Setting the TDRE and RDRF flags affects the status of the interrupt flags.

When the chip is in slave mode (and the addressing format is selected), if the upper 7 bits of SAR match the upper 7 bits of the first frame received after a start condition, the chip operates as the slave device specified by the master device. SAR is assigned to the same address as ICMR, and can be written and read only when the ICE bit is cleared to 0 in ICCR. SAR is initialized to H'00 by a reset.

SARX is assigned to the same address as ICDR, and can be written and read only when the ICE bit is cleared to 0 in ICCR. SARX is initialized to H'01 by a reset and in hardware standby mode.

ICMR is assigned to the same address as SAR. ICMR can be written and read only when the ICE bit is set to 1 in ICCR. ICMR is initialized to H'00 by a reset. Bit 7: MSB-First/LSB-First Select (MLS) Selects whether data is transferred MSB-first or LSB-first. If the number of bits in a frame, excluding the acknowledge bit, is less than 8, transmit data and receive data are stored differently. Transmit data should be written justified toward the MSB side when MLS = 0, and toward the LSB side when MLS = 1. Receive data bits read from the LSB side should be treated as valid when MLS = 0, and bits read from the MSB side when MLS = 1. Do not set this bit to 1 when the I2C bus format is used. Bit 7 MLS 0 1 Description MSB-first LSB-first (Initial value) Rev. 2.0, 11/00, page 527 of 1037 Bit 6: Wait Insertion Bit (WAIT) Selects whether to insert a wait between the transfer of data and the acknowledge bit, in master mode with the I2C bus format. When WAIT is set to 1, after the fall of the clock for the final data bit, the IRIC flag is set to 1 in ICCR, and a wait state begins (with SCL at the low level). When the IRIC flag is cleared to 0 in ICCR, the wait ends and the acknowledge bit is transferred. If WAIT is cleared to 0, data and acknowledge bits are transferred consecutively with no wait inserted. The IRIC flag in ICCR is set to 1 on completion of the acknowledge bit transfer, regardless of the WAIT setting. The setting of this bit is invalid in slave mode.

With the I C bus format (when the FS bit in SAR or the FSX bit in SARX is 0), the data is transferred with one addition acknowledge bit. Bit BC2 to BC0 settings should be made during an interval between transfer frames. If bits BC2 to BC0 are set to a value other than 000, the setting should be made while the SCL line is low. The bit counter is initialized to 000 by a reset and when a start condition is detected. The value returns to 000 at the end of a data transfer, including the acknowledge bit.

ICCR is an 8-bit readable/writable register that enables or disables the I C bus interface, enables or disables interrupts, selects master or slave mode and transmission or reception, enables or 2 disables acknowledgement, confirms the I C bus interface bus status, issues start/stop conditions, and performs interrupt flag confirmation. ICCR is initialized to H'01 by a reset. Bit 7: I C Bus Interface Enable (ICE) 2 Selects whether or not the I C bus interface is to be used. When ICE is set to 1, port pins function as SCL and SDA input/output pins and transfer operations are enabled. When ICE is 2 cleared to 0, the I C bus interface module is disabled, and the internal state is initialized. The SAR and SARX registers can be accessed when ICE is 0. The ICMR and ICDR registers can be accessed when ICE is 1. Bit 7 ICE 0 Description I C bus interface module disabled, with SCL and SDA signal pins set to port function 2 SAR and SARX can be accessed.

Bit 6 IEIC 0 1 Description Interrupts disabled Interrupts enabled (Initial value) Rev. 2.0, 11/00, page 531 of 1037 Bit 5: Master/Slave Select (MST) Bit 4: Transmit/Receive Select (TRS) MST selects whether the I C bus interface operates in master mode or slave mode. 2 TRS selects whether the I C bus interface operates in transmit mode or receive mode. 2 In master mode with the I C bus format, when arbitration is lost, MST and TRS are both reset by hardware, causing a transition to slave receive mode. In slave receive mode with the addressing format (FS = 0 or FSX = 0), hardware automatically selects transmit or receive mode according to the R/W bit in the first frame after a start condition. Modification of the TRS bit during transfer is deferred until transfer of the frame containing the acknowledge bit is completed, and the changeover is made after completion of the transfer. MST and TRS select the operating mode as follows.

When the ACKE bit is 0, the value of the received acknowledge bit is not indicated by the ACKB bit, which is always 0. When the ACKE bit is 0, the TDRE, IRIC, and IRTR flags are set on completion of data transmission, regardless of the value of the acknowledge bit. When the ACKE bit is 1, the TDRE, IRIC, and IRTR flags are set on completion of data transmission when the acknowledge bit is 0, and the IRIC flag alone is set on completion of data transmission when the acknowledge bit is 1. Depending on the receiving device, the acknowledge bit may be significant, in indicating completion of processing of the received data, for instance, or may be fixed at 1 and have no significance. Bit 3 ACKE 0 1 Description The value of the acknowledge bit is ignored, and continuous transfer is performed (Initial value) If the acknowledge bit is 1, continuous transfer is interrupted Rev. 2.0, 11/00, page 533 of 1037 Bit 2: Bus Busy (BBSY) 2 The BBSY flag can be read to check whether the I C bus (SCL, SDA) is busy or free. In master mode, this bit is also used to issue start and stop conditions. A high-to-low transition of SDA while SCL is high is recognized as a start condition, setting BBSY to 1. A low-to-high transition of SDA while SCL is high is recognized as a stop condition, clearing BBSY to 0. To issue a start condition, use a MOV instruction to write 1 in BBSY and 0 in SCP. A retransmit start condition is issued in the same way. To issue a stop condition, use a MOV instruction to write 0 in BBSY and 0 in SCP. It is not possible to write to BBSY in slave mode; the I2C bus interface must be set to master transmit mode before issuing a start condition. MST and TRS should both be set to 1 before writing 1 in BBSY and 0 in SCP. Bit 2 BBSY 0 Description Bus is free [Clearing condition] When a stop condition is detected Bus is busy [Setting condition] When a start condition is detected 2 (Initial value) 1 Bit 1: I C Bus Interface Interrupt Request Flag (IRIC) 2 Indicates that the I C bus interface has issued an interrupt request to the CPU. IRIC is set to 1 at the end of a data transfer, when a slave address or general call address is detected in slave receive mode, when bus arbitration is lost in master transmit mode, and when a stop condition is detected. IRIC is set at different times depending on the FS bit in SAR and the WAIT bit in ICMR. See section 25.3.6, IRIC Setting Timing and SCL Control. The conditions under which IRIC is set also differ depending on the setting of the ACKE bit in ICCR. IRIC is cleared by reading IRIC after it has been set to 1, then writing 0 in IRIC. When the DTC is used, IRIC is cleared automatically and transfer can be performed continuously without CPU intervention.

Although each source has a corresponding flag, caution is needed at the end of a transfer. When the TDRE or RDRF internal flag is set, the readable IRTR flag may or may not be set. The IRTR flag (the DTC* start request flag) is not set at the end of a data transfer up to detection of a retransmission start condition or stop condition after a slave address (SVA) or 2 general call address match in I C bus format slave mode. Even when the IRIC flag and IRTR flag are set, the TDRE or RDRF internal flag may not be set. The IRIC and IRTR flags are not cleared at the end of the specified number of transfers in continuous transfer using the DTC*. The TDRE or RDRF flag is cleared, however, since the specified number of ICDR reads or writes have been completed. Table 25.3 shows the relationship between the flags and the transfer states.

When the IRTR flag is set to 1, the IRIC flag is also set to 1 at the same time. IRTR flag setting is performed when the TDRE or RDRF flag is set to 1. IRTR is cleared by reading IRTR after it has been set to 1, then writing 0 in IRTR. IRTR is also cleared automatically when the IRIC flag is cleared to 0. Note: * This LSI does not incorporate DTC.

AASX is cleared by reading AASX after it has been set to 1, then writing 0 in AASX. AASX is also cleared automatically when a start condition is detected. Bit 4 AASX 0 Description Second slave address not recognized [Clearing condition] (1) When 0 is written in AASX after reading AASX = 1 (2) When a start condition is detected (3) In master mode 1 Second slave address recognized [Setting condition] * When the second slave address is detected in slave receive mode while FSX = 0 (Initial value) Bit 3: Arbitration Lost (AL) 2 This flag indicates that arbitration was lost in master mode. The I C bus interface monitors the bus. When two or more master devices attempt to seize the bus at nearly the same time, if the 2 I C bus interface detects data differing from the data it sent, it sets AL to 1 to indicate that the bus has been taken by another master. AL is cleared by reading AL after it has been set to 1, then writing 0 in AL. In addition, AL is reset automatically by write access to ICDR in transmit mode, or read access to ICDR in receive mode.

(Initial value) Rev. 2.0, 11/00, page 542 of 1037 Bit 0: Acknowledge Bit (ACKB) Stores acknowledge data. In transmit mode, after the receiving device receives data, it returns acknowledge data, and this data is loaded into ACKB. In receive mode, after data has been received, the acknowledge data set in this bit is sent to the transmitting device. When this bit is read, in transmission (when TRS = 1), the value loaded from the bus line (returned by the receiving device) is read. In reception (when TRS = 0), the value set by internal software is read.

When the I C bus interface operating mode is hung because of communications error, and the IICRST bit is then 2 set to 1, the I C bus interface controller is initialized of the internal state, and this allows the 2 internal state of the I C bus interface to be initialized without making port settings or initializing registers. For the detail, refer to section 25.3.9, Initialization of Internal State. 2 The initialization is continuous and the I C bus interface cannot operate, when the IICST bit remains set to 1.

These are shown in figure 25.3. The first frame following a start condition always consists of 8 bits. The serial format is a non-addressing format with no acknowledge bit. This is shown in figure 25.4. 2 Figure 25.5 shows the I C bus timing. The symbols used in figures 25.3 to 25.5 are explained in table 25.4.

The bit length is set by bits BC2 to BC0 in ICMR. The MSBfirst or LSB-first format is selected by bit MLS in ICMR Stop condition. The master device drives SDA from low to high while SCL is high 2 25.3.2 2 Master Transmit Operation In I C bus format master transmit mode, the master device outputs the transmit clock and transmit data, and the slave device returns an acknowledge signal. The transmission procedure and operations synchronize with the ICDR writing are described below. [1] Set bit ICE in ICCR to 1. Set bits MLS, WAIT, and CKS2 to CKS0 in ICMR, and bit IICX in STCR, according to the operating mode. [2] Read the BBSY flag in ICCR to confirm that the bus is free. [3] Set bits MST and TRS to 1 in ICCR to select master transmit mode. [4] Write 1 to BBSY and 0 to SCP. This changes SDA from high to low when SCL is high, and generates the start condition. [5] Then IRIC and IRTR flags are set to 1. If the IEIC bit in ICCR has been set to 1, an interrupt request is sent to the CPU. [6] Write the data (slave address + R/:) to ICDR. After the start condition instruction has been issued and the start conditon has been generated, write data to ICDR. If this procedure is not 2 followed, data may not be output correctly. With the I C bus format (when the FS bit in SAR or the FSX bit in SARX is 0), the first frame data following the start condition indicates the 7-bit slave address and transmit/receive direction. As indicating the end of the transfer, and so the IRIC flag is cleared to 0. After writing ICDR, clear IRIC immediately not to execute other interrupt handling routine. If one frame of data has been transmitted before the IRIC Rev. 2.0, 11/00, page 547 of 1037 clearing, it can not be determine the end of transmission. The master device sequentially sends the transmission clock and the data written to ICDR using the timing shown in figure 25.6. The selected slave device (i.e. the slave device with the matching slave address) drives SDA low at the 9th transmit clock pulse and returns an acknowledge signal. [7] When one frame of data has been transmitted, the IRIC flag is set to 1 at the rise of the 9th transmit clock pulse. After one frame has been transmitted SCL is automatically fixed low in synchronization with the internal clock until the next transmit data is written. [8] Read the ACKB bit in ICSR to confirm that ACKB is cleared to 0. When the slave device has not acknowledged (ACKB bit is 1), operate the step [12] to end transmission, and retry the transmit operation. [9] Write the transmit data to ICDR. As indicating the end of the transfer, and so the IRIC flag is cleared to 0. After writing ICDR, clear IRIC immediately not to execute other interrupt handling routine. The master device sequentially sends the transmission clock and the data written to ICDR. Transmission of the next frame is performed in synchronization with the internal clock. [10] When one frame of data has been transmitted, the IRIC flag is set to 1 at the rise of the 9th transmit clock pulse. After one frame has been transmitted SCL is automatically fixed low in synchronization with the internal clock until the next transmit data is written. [11] Read the ACKB bit in ICSR and confirm ACKB is cleared to 0. When there is data to be transmitted, go to the step [6] to continue next transmission. When the slave device has not acknowledged (ACKB bit is set to 1), operate the step [12] to end transmission. [12] Clear the IRIC flag to 0. And write 0 to BBSY and SCP in ICCR. This changes SDA from low to high when SCL is high, and generates the stop condition.

Figure 25.6 Example of Master Transmit Mode Operation Timing (MLS = WAIT = 0) Rev. 2.0, 11/00, page 549 of 1037 25.3.3 Master Receive Operation In master receive mode, the master device outputs the receive clock, receives data, and returns 2 an acknowledge signal. The slave device transmits data. I C bus interface module consists of the data buffers of ICDRR and ICDRS, so data can be received continuously in master receive mode. For this construction, when stop condition issuing timing delayed, it may occurs the internal contention between stop condition issuance and SCL clock output for next data receiving, and then the extra SCL clock would be outputted automatically or the SCL line would 2 be held to low. And for I C bus interface system, the acknowledge bit must be set to 1 at the last data receiving, so the change timing of ACKB bit in ICSR should be controlled by software. To take measures against these problems, the wait function should be used in master receive mode. The reception procedure and operations with the wait function in master receive mode are described below. [1] Clear the TRS bit in ICCR to 0 to switch from transmit mode to receive mode, and set the WAIT bit in ICMR to 1. Also clear the ACKB bit in ICSR to 0 (acknowledge data setting). [2] When ICDR is read (dummy data read), reception is started, and the receive clock is output, and data received, in synchronization with the internal clock. In order to detect wait operation, set the IRIC flag in ICCR must be cleared to 0. After reading ICDR, clear IRIC immediately not to execute other interrupt handling routine. If one frame of data has been received before the IRIC clearing, it can not be determine the end of reception. [3] The IRIC flag is set to 1 at the fall of the 8th receive clock pulse. If the IEIC bit in ICCR has been set to 1, an interrupt request is sent to the CPU. SCL is automatically fixed low in synchronization with the internal clock until the IRIC flag clearing. If the first frame is the last receive data, execute step [10] to halt reception. [4] Clear the IRIC flag to release from the Wait State. The master device outputs the 9th clock and drives SDA at the 9th receive clock pulse to return an acknowledge signal. [5] When one frame of data has been received, the IRIC flag in ICCR and the IRTR flag in ICSR are set to 1 at the rise of the 9th receive clock pulse. The master device outputs SCL clock to receive next data. [6] Read ICDR. [7] Clear the IRIC flag to detect next wait operation. From clearing of the IRIC flag to negation of a wait as described in step [4] (and [9]) to clearing of the IRIC flag as described in steps [5], [6], and [7], must be performed within the time taken to transfer one byte. [8] The IRIC flags set to 1 at the fall of the 8th receive clock pulse. SCL is automatically fixed low in synchronization with the internal clock until the IRIC flag clearing. If this frame is the last receive data, execute step [10] to halt reception. [9] Clear the IRIC flag in ICCR to cancel wait operation. The master device outputs the 9th clock and drives SDA at the 9th receive clock pulse to return an acknowledge signal. Data can be received continuously by repeating step [5] to [9]. Rev. 2.0, 11/00, page 550 of 1037 [10] Set the ACKB bit in ICSR to 1 so as to return "No acknowledge" data. Also set the TRS bit to 1 to switch from receive mode to transmit mode. [11] Clear IRIC flag to 0 to release from the Wait State. [12] When one frame of data has been received, the IRIC flag is set to 1 at the rise of the 9th receive clock pulse. [13] Clear the WAIT bit to 0 to switch from wait mode to no wait mode. Read ICDR and the IRIC flag to 0. Clearing of the IRIC flag should be after the WAIT = 0. [14] Clear the BBSY bit and SCP bit to 0. This changes SDA from low to high when SCL is high, and generates the stop condition.

The receive procedure and operations in slave receive mode are described below. [1] Set bit ICE in ICCR to 1. Set bits MLS in ICMR and bits MST and TRS in ICCR according to the operating mode. [2] A start condition output by the master device sets the BBSY flag to 1 in ICCR. [3] After the slave device detects the start condition, if the first frame matches its slave address, it functions as the slave device designated as the master device. If the 8th bit data (R/:) is 0, TRS bit in ICCR remains 0 and executes slave receive operation. [4] At the ninth clock pulse of the receive frame, the slave device drives SDA low to acknowledge the transfer. At the same time, the IRIC flag is set to 1 in ICCR. If IEIC is 1 in ICCR, a CPU interrupt is requested. If the RDRF internal flag is 0, it is set to 1 and continuous reception is performed. If the RDRF internal flag is 1, the slave device holds SCL low from the fall of the receive clock until it has read the data in ICDR. [5] Read ICDR and clear IRIC to 0 in ICCR. At this time, the RDFR flag is cleared to 0. Steps [4] and [5] can be repeated to receive data continuously. When a stop condition is detected (a low-to-high transition of SDA while SCL is high), the BBSY flag is cleared to 0 in ICCR.

The transmit procedure and operations in slave transmit mode are described below. [1] Set bit ICE in ICCR to 1. Set bits MLS in ICMR and bits MST and TRS in ICCR according to the operating mode. [2] After the slave device detects a start condition, if the first frame matches its slave address, at the ninth clock pulse the slave device drives SDA low to acknowledge the transfer. At the same time, the IRIC flag is set to 1 in ICCR, and if the IEIC bit in ICCR is set to 1 at this time, an interrupt request is sent to the CPU. If the eighth data bit (R/:) is 1, the TRS bit is set to 1 in ICCR, automatically causing a transition to slave transmit mode. The slave device holds SCL low from the fall of the transmit clock until data is written in ICDR. [3] Clear the IRIC flag to 0, then write data in ICDR. The written data is transferred to ICDRS, and the TDRE internal flag and the IRIC and IRTR flags are set to 1 again. Clear IRIC to 0, then write the next data in ICDR. The slave device outputs the written data serially in step with the clock output by the master device, with the timing shown in figure 25.11. [4] When one frame of data has been transmitted, at the rise of the ninth transmit clock pulse IRIC is set to 1 in ICCR. If the TDRE internal flag is 1, the slave device holds SCL low from the fall of the transmit clock until data is written in ICDR. The master device drives SDA low at the ninth clock pulse to acknowledge the data. The acknowledge signal is stored in the ACKB bit in ICSR, and can be used to check whether the transfer was carried out normally. If TDRE internal flag is set to 0, the data written in ICDR is transferred to ICDRS, then transmission starts and TDRE internal flag and IRIC and IRTR flags are all set to 1 again. [5] To continue transmitting, clear IRIC to 0, then write the next transmit data in ICDR. Steps [4] and [5] can be repeated to transmit continuously. To end the transmission, write H'FF in ICDR so that the SDA may be freed on the slave side. When a stop condition is detected (a low-to-high transition of SDA while SCL is high), the BBSY flag will be cleared to 0 in ICCR.

The initialization is done by setting IICRST bit in STCR register, or clearing ICE bit. For details, see section 25.2.7, Serial/Time control Register (STCR). (1) Range of Initialization The following is initialized by this function: * Internal flags of TDRE and RDRF * Programmable logic controller for signal receiving and sending. * Internal latches used for holding outputs from SCL and SDA pins (wait, clock, data output, etc.). The following is not initialized by this function: * Register values (ICDR, SAR, SARX, ICMR, ICCR, ICSR, and STCR). * Internal latches employed for maintaining data read from the registers which is used for setting or clearing flags on ICMR, ICCR, and ICSR registers. * Values on the ICMR register bit counters (BC2 to BC0). * Interrupt factors currently generated (interrupt factors transferred to the interrupt controller). (2) Precautions on Initialization * Interrupt flags and interrupt factors are not cleared by this function. Thus, you need to clear them own as needed. * Other register flags are not basically cleared, too. Thus, you need to clear them as needed. * When this I2C is initialized with IICRST bit, write data specified by IICRST bit is 2 maintained. When clearing I C, set IICRST bit once, then clear it using the MOV 2 instruction. The I C cannot operate with the IICRST bit set to 1. Don't try to use bit operation instructions such as BCLR. * If you try to clear a flag while data sending or receiving is taking place, I2C module stops sending or receiving at that moment and frees the SCL and SDA pins. When resuming the communication, initialize registers as needed so that the system communication capability may function as intended. Clear function of this module does not directly rewrite value of BBSY bit. However, depending on state of SCL and SDA pins and the timing in which they are made free, BBSY bit can be cleared. Other bits and flags can also be affected by status change. Rev. 2.0, 11/00, page 565 of 1037 In order to avoid these troubles, the following procedures must be observed in initialization of 2 I C. (1) Implement initialization of internal state by setting IICRST bit or ICE bit. (2) Execute the stop condition issue instruction (setting BBSY = 0 and SCP = 0 to write) and wait for a duration equivalent to 2 clocks of the transfer rate. (3) Execute initialization of internal state again by setting IICRST bit or ICE bit. 2 (4) Initialize each I C register (re-setting). Rev. 2.0, 11/00, page 566 of 1037 25.4 Usage Notes (1) In master mode, if an instruction to generate a start condition is immediately followed by an instruction to generate a stop condition, neither condition will be output correctly. To output consecutive start and stop conditions, after issuing the instruction that generates the start condition, read the relevant ports, check that SCL and SDA are both low, then issue the instruction that generates the stop condition. (2) Either of the following two conditions will start the next transfer. Pay attention to these conditions when reading or writing to ICDR. (a) Write access to ICDR when ICE = 1 and TRS = 1 (including automatic transfer from ICDRT to ICDRS) (b) Read access to ICDR when ICE = 1 and TRS = 0 (including automatic transfer from ICDRS to ICDRR) (3) Table 25.5 shows the timing of SCL and SDA output in synchronization with the internal clock. Timings on the bus are determined by the rise and fall times of signals affected by the bus load capacitance, series resistance, and parallel resistance. Table 25.5 I C Bus Timing (SCL and SDA Output) Item SCL output cycle time SCL output high pulse width SCL output low pulse width SDA output bus free time Start condition output hold time Retransmission start condition output setup time Stop condition output setup time Data output setup time (master) Data output setup time (slave) Data output hold time Note: tSDAHO 1. 6tcyc when IICX is 0, 12tcyc when 1.

The AC timing therefore depends on the system clock cycle tcyc, as shown in table 29.6 in section 29, 2 Electrical Characteristics. Note that the I C bus interface AC timing specifications will not be met with a system clock frequency of less than 5 MHz. Rev. 2.0, 11/00, page 567 of 1037 (5) The I C bus interface specification for the SCL rise time tsr is under 1000 ns (300 ns for 2 high-speed mode). In master mode, the I C bus interface monitors the SCL line and synchronizes one bit at a time during communication. If tsr (the time for SCL to go from low 2 to VIH) exceeds the time determined by the input clock of the I C bus interface, the high period of SCL is extended. The SCL rise time is determined by the pull-up resistance and load capacitance of the SCL line. To insure proper operation at the set transfer rate, adjust the pull-up resistance and load capacitance so that the SCL rise time does not exceed the values given in table 25.6. Table 25.6 Permissible SCL Rise Time (tsr) Values Time Indication [ns] tcyc Indication 7.5tcyc Normal mode High-speed mode 1 17.5tcyc Normal mode High-speed mode I C Bus Specification (Max.) 1000 300 1000 300 2 2 IICX 0 = 5 MHz = 8 MHz 937 = 10 MHz 750 (6) The I C bus interface specifications for the SCL and SDA rise and fall times are under 1000 2 ns and 300 ns. The I C bus interface SCL and SDA output timing is prescribed by tScyc and 2 tcyc, as shown in table 25.5. However, because of the rise and fall times, the I C bus interface specifications may not be satisfied at the maximum transfer rate. Table 25.7 shows output timing calculations for different operating frequencies, including the worst-case influence of rise and fall times. 2 tBUFO fails to meet the I C bus interface specifications at any frequency. The solution is either (a) to provide coding to secure the necessary interval (approximately 1 s) between issuance of a stop condition and issuance of a start condition, or (b) to select devices whose input 2 timing permits this output timing for use as slave devices connected to the I C bus. 2 tSCLLO in high-speed mode and tSTASO in standard mode fail to satisfy the I C bus interface specifications for worst-case calculations of t Sr/tSf. Possible solutions that should be investigated include (a) adjusting the rise and fall times by means of a pull-up resistor and capacitive load, (b) reducing the transfer rate to meet the specifications, or (c) selecting devices whose input timing permits this output timing for use as slave devices connected to 2 the I C bus. 2 Rev. 2.0, 11/00, page 568 of 1037 Table 25.7 I C Bus Timing (with Maximum Influence of tSr/tSf) Time Indication (at Maximum Transfer Rate) [ns] tcyc Indication 0.5tSCLO (-tSr) tSCLLO 0.5tSCLO (-tSf) tBUFO 0.5tSCLO-1tcyc (-tSr) tSTAHO 0.5tSCLO-1tcyc (-tSf) tSTASO 1tSCLO (-tSr) tSTOSO 0.5tSCLO+2tcyc (-tSr) tSDASO (master) tSDASO (slave) tSDAHO 3 1tSCLLO* -3tcyc 2 Item tSCLHO tSr/tSf Influence (Max.)

Does not meet the I C bus interface specification. Remedial action such as the following is necessary: (a) secure a start/stop condition issuance interval; (b) adjust the rise and fall times by means of a pull-up resistor and capacitive load; (c) reduce the transfer rate; (d) select slave devices whose input timing permits this output timing. The values in the above table will vary depending on the settings of the IICX bit and bits CKS0 to CKS2. Depending on the frequency it may not be possible to achieve the 2 maximum transfer rate; therefore, whether or not the I C bus interface specifications are met must be determined in accordance with the actual setting conditions. 2. Value when the IICX bit is set to 1. When the IICX bit is cleared to 0, the value is (tSCLL - 6tcyc). 2 3.

Rev. 2.0, 11/00, page 569 of 1037 (7) Precautions on reading ICDR at the end of master receive mode When terminating the master receive mode, set TRS bit to 1, and select "write" for ICCR BBSY = 0 and SCP = 0. This forces to move SDA from low to high level when SCL is at high level, thereby generating the stop condition. Now you can read received data from ICDR. If, however, any data is remaining on the buffer, received data on ICDRS is not transferred to ICDR, thus you won't be able to read the second byte data. When it is required to read the second byte data, issue the stop condition from the master receive state (TRS bit is 0). Before reading data from ICDR register, make sure that BBSY bit on ICCR register is 0, stop condition is generated and bus is made free. If you try to read received data after the stop condition issue instruction (setting ICCR's BBSY = 0 and SCP = 0 to write) has been executed but before the actual stop condition is generated, clock may not be appropriately signaled when the next master sending mode is turned on. Thus, reasonable care is needed for determining when to read the received data. 2 After the master receive is complete, if you want to re-write I C control bit (such as clearing MST bit) for switching the sending/receiving mode or modifying settings, it must be done during period (a) indicated in figure 25.18 (after making sure ICCR register BBSY bit is cleared to 0). Stop condition (a) SDA SCL Internal clock BBSY bit Master receive mode ICDR read inhibit period Bit 0 8 A 9 Start condition The stop condition issue instruction (BBSY = 0 and SCP = 0 set to write) is executed Generation of the stop condition is checked (BBSY = 0 is set to read) Start condition is issued Figure 25.18 Precautions on Reading the Master Receive Data Rev. 2.0, 11/00, page 570 of 1037 (8) Notes on Start Condition Issuance for Retransmission Figure 25.19 shows the timing of start conditon issuance for retransmission, and the timing for subsequently writing data to ICDR, together with the corresponding flowchart.

The A/D-converted data is 10-bit data. Upon completion of software-triggered A/D conversion, the 10-bit result data is transferred to ADR and the data is retained until the next softwaretriggered A/D conversion completion. The upper 8 bits of the data are stored in the upper bytes (bits 15 to 8) of ADR, and the lower 2 bits are stored in the lower bytes (bits 7 and 6). Bits 5 to 0 are always read as 0. ADR can be read by the CPU at any time, but the ADR value during A/D conversion is not fixed. The upper bytes can always be read directly, but the data in the lower bytes is transferred via a temporary register (TEMP). For details, see section 26.3, Interface to Bus Master. ADR is a 16-bit read-only register which is initialized to H'0000 at a reset, and in module stop mode, standby mode, watch mode, subactive mode and subsleep mode. 26.2.2 Hardware-Triggered A/D Result Register (AHR) AHRH Bit : 15 0 R 14 0 R 13 0 R 12 0 R 11 0 R 10 0 R 9 0 R 8 0 R 7 0 R 6 0 R 5 -- 0 -- AHRL 4 -- 0 -- 3 -- 0 -- 2 -- 0 -- 1 -- 0 -- 0 -- 0 -- AHR9 AHR8 AHR7 AHR6 AHR5 AHR4 AHR3 AHR2 AHR1 AHR0 Initial value : R/W : The hardware-triggered A/D result register (AHR) is a register that stores the result of an A/D conversion started by hardware (internal signal: ADTRG and DFG) or by external trigger input ($'75*).

The A/D status register (ADCSR) is an 8-bit register that can be used to start or stop A/D conversion, or check the status of the A/D converter. A/D conversion starts when 1 is written in SST flag. A/D conversion can also start by setting HST flag to 1 by hardware- or external-triggering. For ADTRG start by HSW timing generator in hardware triggering, see section 28.4, HSW Timing Generator. When conversion ends, the converted data is stored in the software-triggered A/D result register (ADR) or hardware-triggered A/D result register (AHR), and the SST or HST bit is cleared to 0. If software-triggering and hardware- or external-triggering are generated at the same time, priority is given to hardware- or external-triggering. ADCSR is an 8-bit register which is initialized to H'01 by a reset, and in module stop mode, standby mode, watch mode, subactive mode and subsleep mode.

Therefore, in accesses by the bus master, the upper byte is accessed directly, but the lower byte is accessed via a temporary register (TEMP). A data reading from ADR and AHR is performed as follows. When the upper byte is read, the upper byte value is transferred to the CPU and the lower byte value is transferred to TEMP. Next, when the lower byte is read, the TEMP contents are transferred to the CPU. When reading ADR and AHR, always read the upper byte before the lower byte. It is possible to read only the upper byte, but if only the lower byte is read, incorrect data may be obtained. Figure 26.3 shows the data flow for ADR access. The data flow for AHR access is the same.

The SST bit remains set to 1 during A/D conversion, and is automatically cleared to 0 when conversion ends. Conversion can be software-triggered on any of the 12 channels provided by analog input pins AN0 to ANB. Bits SCH3 to SCH0 in ADCR select the analog input pin used for softwaretriggered A/D conversion. Pins AN8 to ANB are also available for hardware- or externaltriggered conversion. When conversion ends, SEND flag in ADCSR bit is set to 1. If ADIE bit in ADCSR is also set to 1, an A/D conversion end interrupt occurs. If the conversion time or input channel selection in ADCR needs to be changed during A/D conversion, to avoid malfunctions, first clear the SST bit to 0 to halt A/D conversion. If software writes 1 in the SST bit to start software-triggered conversion while hardware- or external-triggered conversion is in progress, the hardware- or external-triggered conversion has priority and the software-triggered conversion is not executed. At this time, BUSY flag in ADCSR is set to 1. The BUSY flag is cleared to 0 when the hardware-triggered A/D result register (AHR) is read. If conversion is triggered by hardware while software-triggered conversion is in progress, the software-triggered conversion is immediately canceled and the SST flag is cleared to 0, and SCNL flag in ADCSR is set to 1. The SCNL flag is cleared when software writes 1 in the SST bit to start conversion after the hardware-triggered conversion ends. Rev. 2.0, 11/00, page 588 of 1037 26.4.2 Hardware- or External-Triggered A/D Conversion The system contains the hardware trigger function that allows to turn on A/D conversion at a specified timing by use of the hardware trigger (internal signals: ADTRG and DFG) and the incoming external trigger ($'75*). This function can be used to measure an analog signal that varies in synchronization with an external signal at a fixed timing. To execute hardware- or external-triggered A/D conversion, select appropriate start factor in TRGS1 and TRGS0 bits in ADTSR. When the selected triggering occurs, HST flag in ADCSR is set to 1 and A/D conversion starts. The HST flag remains 1 during A/D conversion, and is automatically cleared to 0 when conversion ends. For ADTRG start by HSW timing generator in hardware triggering, see section 28.4, HSW Timing Generator. Setting of the analog input pins on four channels from AN8 to ANB can be modified with the hardware trigger or the incoming external trigger. Setting is done from HCH1 and HCH0 bits on ADCR. Pins AN8 to ANB are also available for software-triggered conversion. When conversion ends, HEND flag in ADCSR is set to 1. If ADIE bit in ADCSR is also set to 1, an A/D conversion end interrupt occurs. If the conversion time or input channel selection in ADCR needs to be changed during A/D conversion, to avoid malfunctions, first clear the HST flag to 0 to halt A/D conversion. If software writes 1 in the SST bit to start software-triggered conversion while hardware- or external-triggered conversion is in progress, the hardware- or external-triggered conversion has priority and the software-triggered conversion is not executed. At this time, BUSY flag in ADCSR is set to 1. The BUSY flag is cleared to 0 when the hardware-triggered A/D result register (AHR) is read. If conversion is triggered by hardware while software-triggered conversion is in progress, the software-triggered conversion is immediately canceled and the SST flag is cleared to 0, and SCNL flag in ADCSR is set to 1 (the SCNL flag is cleared when software writes 1 in the SST bit to start conversion after the hardware-triggered conversion ends). The analog input channel changes automatically from the channel that was undergoing software-triggered conversion (selected by bits SCH3 to SCH0 in ADCR) to the channel selected by bits HCH1 and HCH0 in ADCR for hardware- or external-triggered conversion. After the hardware- or external-triggered conversion ends, the channel reverts to the channel selected by the software-triggered conversion channel select bits in ADCR. Hardware- or external-triggered conversion has priority over software-triggered conversion, so the A/D interrupt-handling routine should check the SCNL and BUSY flags when it processes the converted data. Rev. 2.0, 11/00, page 589 of 1037 26.5 Interrupt Sources When A/D conversion ends, SEND or HEND flag in ADCSR is set to 1. The A/D conversion end interrupt can be enabled or disabled by ADIE bit in ADCSR. Figure 26.4 shows the block diagram of A/D conversion end interrupt.

For the address to trap, set to the address where the first byte of an instruction exists. In the case of other addresses, it may not be considered that the condition has been satisfied. Bit 0 of this register is fixed at 0. The address to trap becomes an even address. The range where comparison is made is H'000000 to H'FFFFFE. Rev. 2.0, 11/00, page 594 of 1037 27.3 Precautions in Usage Address trap interrupt arises 2 states after prefetching the trap address. Trap interrupt may occur after the trap instruction has been executed, depending on a combination of instructions immediately preceding the setting up of the address trap. If the instruction to trap immediately follows the branch instruction or the conditional branch instruction, operation may differ, depending on whether the condition was satisfied or not, or the address to be stacked may be located at the branch. Figures 27.2 to 27.22 show specific operations. For information as to where the next instruction prefetch occurs during the execution cycle of the instruction, see appendix A.5 of this manual or section 2.7 Bus State during Execution of Instruction of the H8S/2600, H8S/2000 Series Programming Manual. (R:W NEXT is the next instruction prefetch.) 27.3.1 Basic Operations After terminating the execution of the instruction being executed in the second state from the trap address prefetch, the address trap interrupt exception handling is started.

However, if the address trap interrupt arises before starting execution of the NMI interrupt processing, transition is made to the address trap exception handling. The address to be stacked is the starting address of the NMI interrupt processing.

The CREF signal is used if the reference signal to control the phase of the capstan cannot be shared with the REF30 signal in REC mode. Each signal generator consists of a 16-bit counter which has the servo clock s/2 (or s/4) as its clock source, a reference period register and a comparator. The value set in the reference period register should be 1/2 of the desired reference signal period. 28.3.2 Block Diagram Figure 28.6 shows the block diagram of the REF30 signal generator. Figure 28.7 shows that of the CREF signal generator.

It is a 16-bit write-only register accessible by a word only. If a read is attempted, an undetermined value is read out. The value set in RFD should be 1/2 of the desired reference signal period. Care is required when VD is unstable, such as when the field is weak (Synchronization with VD cannot be acquired if a value less than 1/2 is set when in REC). When data is written in RFD, it is stored in the buffer once, and then fetched into RFD by a match signal of the comparator. (The data which generates the reference signal is updated from time to time by the match signal.) An enforced write, such as initial setting, etc., should be done by a dummy read of RFD. If a byte-write in RFD is attempted, no operation is assured. RFD is initialized to H'FFFF by a reset, stand-by, or module stop.

To generate REF30 signals, set the half-period value to the reference period register 1 (RFD) corresponding to the 50% duty cycle. When in playback, REF30 signals are generated by operating REF30 signal generator in free-run. The generator has the external signal synchronization function built-in, and if bit 4 (REX) of the reference period mode register (RFM) is set to 1, it generates REF30 signals from external signals (EXTTRG). In record mode, the reference signals are generated from the VD signal generated in the sync signal detection circuit. Any VD drop-out caused by weak field intensity, etc., is compensated by a set value of RFD. To cope with the VD noises, the generator performs automatically the VD masking for a time period about 75% of the RFD setting after REF30 signal was changed due to VD. In record mode, the generation of the reference signals either by VD or free-run operation can be controlled automatically or by software, using the V noise detection signal detected in the sync signal detection circuit. Select which is used by setting bit 6 (VNA) or 5 (CVS) of RFM. The phase of the toggle output of the REF30 signal is cleared to L level when the signal mode transits from PB to REC (ASM). Also the frame servo function can be set, allowing to control the phase of REF30 signals with the field signal detected in the sync signal detection circuit. Use bit 2 (OD/EV) of RFM for such control. See section 28.13.5(2), CTL Mode Register (CTLM) as for switching over between PB, ASM and REC. (2) Operation of the Mask Circuit The REF30 signal generators have a toggle mask circuit and counter mask (counter set signal mask) circuit built-in. Each mask circuit masks irregular VD signals which may occur when the VD signal is unstable because of weak field intensity, etc., in record mode. The toggle mask and counter mask circuits mask the VD automatically for about 75% of double the time period set in the reference period register 1 (RFD) after a VD signal was detected (see figure 28.9). If a VD signal dropped out and V was compensated, the toggle mask circuit begins masking. The counter mask circuit does not do so for about 25% of the time period. If a VD signal was detected during such time period, it does masking for about 75% of the time period. If not detected, it does for the same time period after V was compensated (see figures 28.10 and 28.11). Rev. 2.0, 11/00, page 635 of 1037 (3) Timing of the REF30 Signal Generation Figures 28.8, 28.9, 28.10, 28.11 and 28.12 show the timing of the generation of REF30 and REF30P signals.

To generate CREF signals, set the half-period value to the reference period register 2 (CRF). If the set value matches the counter value, a toggle waveform is generated corresponding to the 50% duty cycle, and a one-shot pulse signal is output at the rising edge of the waveform. The counter of the CREF signal generator is initialized to H'0000 and the phase of the toggle is cleared to L level at the mode transition of PB (ASM) to REC. The timing of clearing is selectable between immediately after the transition from PB (ASM) to REC and the timing of DVCFG2 after the transition. Use bit 3 (CRD) of the reference period mode register (RFM) for the selection. In the capstan phase error detection circuit, either the REF30 signal or CREF signal can be selected for the reference signal. Use either of them according to the use of the system. Use the CREF signal to control the phase of the capstan at a period which is different from the period used to control the phase of the drum. As for the switching between REF30 and CREF in the capstan phase control, see section 28.9.4(3) Capstan Phase Error Detection Control Register (CPGCR).

The 5-bit counter counts the DFG pulses following a DPG pulse. Each of them determines the timing to reset the 16-bit timer for each field. The matching circuit compares the timing data in the most significant 16 bits of FIFO with the 16-bit timer, and controls the output of pattern data set in the least significant 15 bits of FIFO. The 16-bit timer is a timer clocked by a s/4 clock source, and can be used as a PPG (Programmable Pattern Generator) as well as a free-running counter (FRC). If used as a free-running counter, it is cleared by overflow (FRCOVF) of the Prescaler unit. Accordingly, two free-running counter operate in sync. 28.4.2 Block Diagram Figure 28.22 shows a block diagram of the HSW timing generator.

The FIFO has two 31-bit x 10-stage data buffers, its operating status being controlled by HSM1 and HSM2. Data is stored in the 31-bit data buffer. The values of FTPRA, FTPRB and the timer counter are compared, and if they match, the 15-bit pattern data is output to each function. AudioFF, VideoFF and PPG (P70 to P77) are pin outputs, ADTRG is the A/D converter hardware start signal, Vpulse and Mlevel signals are the signals to generate the additional V pulses, and HSW and NHSW signals are the same with VideoFF signals used for the phase control of the drum. In free-run mode (when FRT bit of HSM2 = 1), the 16-bit timer counter is initialized when the prescaler unit overflows, or by a signal indicating a match between DFCRA, DFCRB and the DFG counter in DFG reference mode.

Rev. 2.0, 11/00, page 668 of 1037 28.4.6 Description of Operation (a) 5-bit DFG counter The 5-bit DFG counter takes counts by the edges of DFG selected by the EDG bit of HSW mode register 2. The 5-bit DFG counter is cleared by the DPG's rise or when 1 was written in the CCLR bit of DFG reference register 1. (b) 16-bit Timer Counter DFG reference mode or free-run mode can be selected for the 16-bit timer counter. * DFG Reference Mode DFG reference mode is based on the DFG signal. When the DFG reference registers 1 and 2 and the 5-bit DFG counter value match, the 16-bit timer counter is initialized, and that point becomes the starting of the FIFO output. In DFG reference mode, the FGR2OFF bit of the HSW mode register 2 can be used to select between using only the DFG reference register 1 to set the starting of the FIFO output or using both DFG reference registers 1 and 2 to set the starting of the FIFO1 and FIFO2 outputs, respectively. When using only the DFG reference register 1 to set the starting, continuous values should be set as the timing patterns for FIFO1 and FIFO2. * Free-run Mode Free-run mode is to operate together with the prescaler unit. An overflow of the 18-bit free-running counter in the prescaler unit initializes the 16-bit timer counter, and that point becomes the starting of the FIFO output. (c) Matching Circuit The matching circuit compares the timing pattern value of FIFO with the 16-bit timer counter value, and if they match, it generates a trigger signal to output the pattern data for the FIFO's next stage. (d) FIFO FIFO generates the head-switching signal used in the VCR and the pattern data necessary for servo control. Data is set in FIFO by the FIFO timing pattern registers 1 and 2 and the FIFO output pattern registers 1 and 2. FIFO has two modes, i.e. single mode and loop mode. In either mode, output of 20 stages of FIFO1 + FIFO2 or output of only 10 stages of FIFO1 can be selected. * Single Mode In single mode, the output pattern data is output each time the timing data matches. The data, once output, is lost, and the internal pointer is decremented by 1. When the last data was output, it stops operation until data is written again. When it is used in the 20stage output mode, writing in FIFO1 and FIFO2 has to be controlled by software. Rev. 2.0, 11/00, page 669 of 1037 * Loop Mode In loop mode, the output pattern cycles repeatedly from stage 0 through the final stage selected in the HSW loop number setting register. As in single mode, the output pattern data is output each time the timing data matches. In loop mode, the FIFO data is retained. When loop mode is active, data can be rewritten for each FIFO group. After confirming with the OFG bit of the HSW mode register 2 which FIFO group is outputting, clear the FIFO group which is not outputting and write data for the entire FIFO group. Writing has to be completed before the rewritten FIFO group starts operation. Partial rewriting in the FIFO is not possible, because the write pointer is outside the loop stages. Figures 28.23 and 28.24 show examples of the timing waveform and its operation of the HSW timing generator.

Rev. 2.0, 11/00, page 673 of 1037 After this sequence is repeated and all the pattern data set in FIFO1 is output, the pattern data of FIFO2 is output. After the pattern data is output, the pointer is decremented by 1. Care is required, however, because matching of tA0 is not detected until data is written in FIFO2. Matching of tB0 also is not detected until data is written in FIFO1 again.

Rev. 2.0, 11/00, page 674 of 1037 28.4.7 Interrupt The HSW timing generator generates an interrupt under the following conditions. (1) IRRHSW1 occurred when pattern data was written (OVWA, OVWB = 1) and FIFO was full (FULL). (2) IRRHSW1 occurred when matching was detected and the STRIG bit of FIFO was 1. (3) IRRHSW1 occurred when the values of the 16-bit timer counter and 16-bit timing pattern register matched. (4) IRRHSW2 occurred when the 16-bit timer counter was cleared. (5) IRRHSW2 occurred when a VD signal (capture signal of the timer capture register) was received in PB mode. (2) and (3), as well as (4) and (5), are switched over by ISEL1 and ISEL2. Rev. 2.0, 11/00, page 675 of 1037 28.4.8 Cautions (1) When both the 5-bit DFG counter and 16-bit timer counter are operating, the latter is not cleared if input of DPG and DFG signals is stopped. This leads to free-running of the 16-bit timer counter, and periodical detection of matching by the 16-bit timer counter. In such a case, the period of the output from the HSW timing generator is independent from DPG or DFG. (2) Specify the mode setting bit (LOP) of the HSW mode register 2 (HSM2) immediately before writing the FIFO data. (3) Input the rising edge of DPG and DFG count edge at different timings. If the same timing was input, counting up of DFG and clearing of the 5-bit DFG counter occurs simultaneously. In this case, the latter will take precedence. This leads to the 5-bit DFG counter's lag by 1. Figure 28.25 shows the input timing of DPG and DFG. (4) If stop of the drum system is required when FIFO output is being used in the 20-stage output mode, rewrite the SOFG bit of HSM2 register 0 1 0 by software, and initialize the FIFO output stage to the FIFO1 side without fail. Also clear and rewrite the data of FIFO1 and FIFO2.

A pre-amplifier output comparison result signal is input from the COMP pin. The signal output at the C.Rotary pin is a Chroma signal processing control signal. The signal output at the H.Amp SW pin is a pre-amplifier output select signal. To reduce the width of noise bars, the C.Rotary and H.Amp SW signals are synchronized to the horizontal sync signal (OSCH). OSCH is made by adding supplemented H, which has been separated from the Csync signal in the sync signal detector circuit. For more details of OSCH, see section 28.15, Sync Signal Detector. If the C.Rotary, H.Amp SW or COMP pin does not require this circuit to configure a VCR system, it can be used as an I/O port. 28.5.2 Block Diagram Figure 28.26 shows the block diagram of this circuit.

A digital counter detects the speed deviation from a preset value. The speed error data is processed and added to phase error data in a digital filter. This filter controls a pulse-width modulated (PWM) output, which controls the revolution speed and phase of the drum. The DFG input signal is reshaped into a square wave by a reshaping circuit, and sent to the speed error detector as the DFG signal. The speed error detector uses the system clock to measure the period of the DFG signal, and detects the deviation from a preset data value. The preset data is the value that would result from measuring the DFG signal period with the clock signal if the drum motor was running at the correct speed. The error detector operates by latching a counter value when it detects an edge of the DFG signal. The latched count provides 16 bits of speed error data for the digital filter to operate on. The digital filter processes and adds the speed error data to phase error data from the drum phase control system, then sends the result to the pulse-width modulator as drum error data. 28.6.2 Block Diagram Figure 28.27 shows a block diagram of the drum speed error detector.

Set a signed data to DFRUDR (bit 15 is a sign-setting bit). When lock is being detected, if the drum speed is detected within the lock range, the lock counter which has been set by DFRCS 1 and 0 bits of the DFVCR register counts down. If the set value of DFRCS 1 and 0 matches the number of times of occurrence of locking, the computation of the digital filter in the drum phase system can be controlled automatically. Also, if the DFG speed error data is beyond the DFRUDR value while the limiter function is in use, the DFRUDR value can be used as the data for computation by the digital filter. DFRUDR is a 16-bit write-only register. Only a word access is valid. If a byte access is attempted, operation is not assured. No read is valid.

When lock is being detected, if the drum speed is detected within the lock range, the lock counter which has been set by the DFRCS1 and DFRCS0 bits of the DFVCR register counts down. If the set value of DFRCS1 and DFRCS0 matches the number of times of occurrence of locking, the computation of the digital filter in the drum phase system can be controlled automatically. Also, if the DFG speed error data is under the DFRLDR value when the limiter function is in use, the DFRLDR value can be used as the data for computation by the digital filter.

It sets the drum lock flag if it detected the set number of times of occurrence of drum lock. If an NCDFG signal is detected outside the lock range after data is written in DFRCS1 and 0, data is stored in the lock counter. Note: If DFRCS1 or DFRCS0 is read-accessed, the counter value is read out. If bit 3 (drum lock flag) is 1 and the drum lock counter's value is 3, it indicates that the drum speed system is locked. The drum look counter stops until lock is released after underflow.

The reference value set in DFPR is preset in the counter by the NCDFG signal, and counts down by the selected clock. The timing of the counter presetting and the error data latching can be selected between the rising or falling edge of the NCDFG signal. See section 28.14.4, DFG Noise Removal Circuit. The error data detected is sent to the digital filter circuit. The error data is signed binaries. It takes a positive number (+) if the speed is slower than the specified speed, a negative number (-) if the speed is faster, or 0 if it correct (revolving at the specified speed). Figure 28.28 shows an example of operation to detect the drum speed. (a) Setting the error data limit A limit can be set to the error data sent to the digital filter circuit using the DFG lock data register (DFRUDR, DFRLDR). Set the upper limit of the error data in DFRUDR and the lower limit in DFRLDR, and write 1 in the DFRFON bit. If the error data is beyond the limit range, the DFRLDR value is sent if a negative number is latched, or the DFRUDR value is sent if a positive one is latched, as a limit value. Be sure to turn off the limit setting (DFRFON = 0) when you set the limit value. If the limit was set with the limit setting on (DFRFON = 1), result of computation is not assured. (b) Lock detection If an error data was detected within the lock range set in the lock data register, the drum lock flag (DF-R/UNR) is set by the number of the times of occurrence of locking set by the DFRCS1 and DFRCS0 bits, and an interrupt is requested (IRRDRM2) at the same time. The number of the occurrence of locking (once to 4 times) can be specified when setting the flag. Use the DFRCS1 and DFRCS0 bits for this purpose. Also, if bit 5 (DPHA bit) of the drum system digital filter control register (DFIC) is 0 (phased system digital filter computation off) and the DPCNT bit is 1, turning on/off of the phase system digital filter computation can be controlled automatically by the status of lock detection. (c) Drum system speed error detection counter The drum system speed error detection counter stops the counter and sets the overflow flag (DFOVF) when the overflow occurred. At the same time, it generates an interrupt request (IRRDRM1). Clear DFOVF by writing 0 after reading 1. If setting the flag and writing 0 take place simultaneously, the latter is nullified. Rev. 2.0, 11/00, page 689 of 1037 (d) Interrupt request IRRDRM1 is generated by the NCDFG signal latch and the overflow of the error detection counter. IRRDRM2 is generated by detection of lock (after the detection of the number of times of setting).

This change alters the horizontal sync signal (fH), causing skew. To correct the skew, the drum motor speed must be shifted to a different speed in each trick play mode, so as to obtain the normal horizontal sync frequency. To shift the drum motor speed, software should modify the value written in the DFG preset data register in the speed error detector. This fH correction can be expressed in terms of the basic frequency fF of the drum as follows. fF = N0 x fF0 N0+H (1-n) Legend: n: H: N0: fF0: Speed multiplier (FWD = positive, REV = negative) H alignment (1.5H in standard mode, 0.75H in 2x mode, and 0.5H in 3x mode for VHS and systems; 1H for an 8-mm VCR) Standard H numbers within field Field frequency NTSC: N0 = 262.5, fF0 = 59.94 PAL: N0 = 312.5, fF0 = 50.00 Rev. 2.0, 11/00, page 691 of 1037 28.7 28.7.1 Drum Phase Error Detector Overview Drum phase control must start operating after the drum motor is brought to the correct revolution speed by the speed control system. Drum phase control works as follows in record and playback. Record: Phase is controlled so that the vertical blanking intervals of the recorded video signal will line up along the bottom edge of the tape. Playback: Phase is controlled so as to trace the recorded tracks accurately. A digital counter detects the phase deviation from a preset value. The phase error data is processed and added to speed error data in a digital filter. This filter controls a pulse-width modulated (PWM) output, which controls the rotational phase and speed of the drum. The DPG signal from the drum motor is reshaped into a rectangular pulse waveform by a reshaping circuit, and sent to the phase error detector. The phase error detector compares the phase of the DPG pulse (tackle pulse), which contains video head phase information, with a reference signal. In the actual circuit, the comparison is carried out by comparing the head-switching (HSW) signal, which is delayed by a counter that is reset by DPG, with a reference signal value. The reference signal is the REF30 signal, which differs between record and playback as follows. Record: Vsync signal extracted from the video signal to be recorded (frame rate signal, actually 1/2 Vsync) Playback: 30 Hz or 25 Hz signal divided from the system clock 28.7.2 Block Diagram Figure 28.29 shows a block diagram of the drum phase error detector.

The reference values set in DPPR1 and DPPR2 are preset in the counter by the REF30P signal, and counted up by the clock selected. The latch of the error data can be selected between the rising or falling edge of HSW (NHSW). The error data detected in the error data automatic transmission mode (DFEPS bit of DFUCR = 0) is sent to the digital filter circuit automatically. In software transmission mode (DFEPS bit of DFUCR = 1), the data written in DPER1 and DPER2 is sent to the digital filter circuit. The error data is signed binary. It takes a positive number (+) if the phase is behind the specified phase, a negative number (-) if in advance of the specified phase, or 0 if it had no phase error (revolving at the specified phase). Figures 28.30 and 28.31 show examples of operation to detect a drum phase error. (a) Drum phase error detection counter The drum phase error detection counter stops the counter when overflow or latch occurred. At the same time, it generates an interrupt request (IRRDRM3), setting the overflow flag (DPOVF) if overflow occurred. Clear DPOVF by writing 0 after reading 1. If setting the flag and writing 0 take place simultaneously, the latter is nullified. (b) Interrupt request IRRDRM3 is generated by the HSW (NHSW) signal latch and the overflow of the error detection counter.

The REF30 signal is used for the reference signal, and the HSW signal (VideoFF) or HHSW signal (NarrowFF) from the HSW timing generator is used for the comparing signal. In record mode, however, the phase of the REF30 signal is the same as that of the vertical sync signal (Vsync) because the reference signal generator (REF30 generator) is reset by the vertical sync signal (Vsync) in the video signals. The error detection counter performs the data latching operation at the rising or falling edge of the HSW signal. The digital filter circuit performs computation using this data as 20-bit phase error data. After processing and adding the phase error data and the speed error data from the drum speed control system, the digital filter circuit sends the data as the error data of the drum system to the PWM modulation circuit. Rev. 2.0, 11/00, page 700 of 1037 28.8 28.8.1 Capstan Speed Error Detector Overview Capstan speed control operates so as to hold the capstan motor at a constant revolution speed, by measuring the period of the CFG signal. A digital counter detects the speed deviation from a preset value. The speed error data is added to phase error data in a digital filter. This filter controls a pulse-width modulated (PWM) output, which controls the revolution speed and phase of the capstan motor. The CFG input signal is downloaded by the comparator circuit, then reshaped into a square wave by a reshaping circuit, divided by the CFG divider, and sent to the speed error detector as the DVCFG signal. The speed error detector uses the system clock to measure the period of the DVCFG signal, and detects the deviation from a preset data value. The preset data is the value that would result from measuring the DVCFG signal period with the clock signal if the capstan motor was running at the correct speed. The error detector operates by latching a counter value when it detects an edge of the DVCFG signal. The latched count provides 16 bits of speed error data for the digital filter to operate on. The digital filter adds the speed error data to phase error data from the capstan phase control system, then sends the result to the pulse-width modulator as capstan error data. 28.8.2 Block Diagram Figure 28.32 shows a block diagram of the capstan speed error detector.

The preset data is referenced to H'8000*, and can be calculated from the following equation. CFG speed preset data =H'8000 - ( s/n - 2) DVCFG frequency s: Servo clock frequency in Hz (fOSC/2) DVCFG frequency: In Hz The constant 2 is the preset interval (see figure 28.33). s/n: Clock source of the selected counter CFPR is a 16-bit write-only register.

CFPR is initialized to H'0000 by a reset, stand-by or module stop. Note: * The preset data value is calculated so that the counter will reach H'8000 when the error is zero. When the counter value is latched as error data in the CFG speed error data register (CFER), however, it is converted to a value referenced to H'0000.

CFER is a 16-bit data register. When the speed of the capstan motor is correct, the data latched in CFER is H'0000. Negative data will be latched if the speed is too fast, and positive data if the speed is too slow. The CFER value is sent to the digital filter either automatically or by software. CFER is a 16-bit readable/writable register. CFER is accessible by word access only. Byte access gives unassured results. CFER is initialized to H'0000 by a reset, and in module stop mode and standby mode. See the note on the CFG speed preset data register (CFPR) in section 28.8.4 (1).

When lock is being detected, if the capstan speed is detected within the lock range, the lock counter which has been set by the CFRCS1 and CFRCS0 bits of the CFVCR register counts down. If the set value of CFRCS1 and CFRCS0 matches the number of times of occurrence of locking, the computation of the digital filter in the capstan phase system can be controlled automatically. Also, if the CFG speed error data is beyond the CFRUDR value when the limiter function is in use, the CFRUDR value can be used as the data for computation by the digital filter. CFRUDR is a 16-bit write-only register. Only a word access is valid. If a byte access is attempted, operation is not assured. A read is invalid. If a read is attempted, an undetermined value is read out. It is initialized to H'7FFF by a reset, stand-by or module-stop.

When lock is being detected, if the drum speed is detected within the lock range, the lock counter which has been set by the CFRCS1 and CFRCS0 bits of the CFVCR register counts down. If the set value of CFRCS1 and CFRCS0 matches the number of times of occurrence of locking, the computation of the digital filter in the drum phase system can be controlled automatically. Also, if the CFG speed error data is under the CFRLDR value when the limiter function is in use, the CFRLDR value can be used as the data for computation by the digital filter. CFRLDR is a 16-bit write-only register. Only a word access is valid. If a byte access is attempted, operation is not assured. No read is valid. If a read is attempted, an undetermined value is read out. It is initialized to H'8000 by a reset, stand-by or module-stop.

It is cleared by writing 0. Write 0 after reading 1. Also, setting has the highest priority in this flag. If a flag set and 0 write occurs simultaneously, the latter is nullified.

It sets the capstan lock flag if it detected the set number of times of occurrence of capstan lock. If a DVCFG signal is detected outside the lock range after data is written in CFRCS1 and CFRCS0, data is stored in the lock counter. Note: If CFRCS1 or CFRCS0 is read-accessed, the counter value is read out. If bit 3 (capstan lock flag) is 1 and the capstan lock counter's value is 3, it indicates that the capstan speed system is locked. The capstan look counter stops until lock is released after underflow. Bit 1 CFRCS1 0 1 Bit 0 CFRCS0 0 1 0 1 Description Underflow after lock was detected once Underflow after lock was detected twice Underflow after lock was detected three times Underflow after lock was detected four times (Initial value) 28.8.5 Description of Operation The capstan speed error detector detects the speed error based on the reference value set in the CFG speed preset register (CFPR). The reference value set in CFPR is preset in the counter by the DVCFG signal, and counts down by the selected clock. The timing of the counter presetting and the error data latching can be selected between the rising or falling edge of the DVCFG signal. See section 28.14.3, CFG Frequency Divider. The error data detected is sent to the digital filter circuit. The error data is signed binaries. It takes a positive number (+) if the speed is slower than the specified speed, a negative number (-) if the speed is faster, or 0 if it had no error (revolving at the specified speed). Figure 28.33 shows an example of operation to detect the capstan speed. (a) Setting the error data limit A limit can be set to the error data sent to the digital filter circuit using the CFG lock data register (CFRUDR, CFRLDR). Set the upper limit of the error data in CFRUDR and the lower limit in CFRLDR, and write 1 in the CFRFON bit. If the error data is beyond the limit range, the CFRLDR value is sent if a negative number is latched, or the CFRUDR value is sent if a positive one is latched, as a limit value. Be sure to turn off the limit setting (CFRFON = 0) when you set the limit value. If the limit was set with the limit setting on (CFRFON = 1), result of computation is not assured. Rev. 2.0, 11/00, page 708 of 1037 (b) Lock detection If error data was detected within the lock range set in the lock data register, the capstan lock flag (CF-R/UNR) is set by the number of the times of occurrence of locking set by the CFRCS1 and CFRCS0 bits, and an interrupt is requested (IRRCAP2) at the same time. The number of the occurrence of locking (once to 4 times) can be specified when setting the flag. Use the CFRCS1 and CFRCS0 bits for this purpose. Also, if bit 5 (CPHA bit) of the capstan system digital filter control register (CFIC) is 0 (phased system digital filter computation off) and the DPCNT bit is 1, turning on/off of the phase system digital filter computation can be controlled automatically by the status of lock detection. (c) Capstan system speed error detection counter The capstan system speed error detection counter stops the counter and sets the overflow flag (CFOVF) when overflow occurred. At the same time, it generates an interrupt request (IRRCAP1). Clear CFOVF by writing 0 after reading 1. If setting the flag and writing 0 take place simultaneously, the latter is nullified. (d) Interrupt request IRRCAP1 is generated by the DVCFG signal latch and the overflow of the error detection counter. IRRCAP2 is generated by detection of lock (after the detection of the number of times of setting). Error data latch signal (DVCFG) Preset data load Preset period (2 counts) Specified speed value Counter -value +value Preset value Latch data 0 (no error) Figure 28.33 Example of the Operation of the Capstan Speed Error Detection Rev. 2.0, 11/00, page 709 of 1037 28.9 28.9.1 Capstan Phase Error Detector Overview The capstan phase control system is required to start operation after the capstan motor has arrived at the specified speed under the control of the speed control system. The capstan phase control system operates in the following way in record/playback mode. In record mode: Controls the tape running so that it may run at a specified speed together with the speed control system. In playback mode: Controls the tape running so that the recorded track may be traced correctly. Any error deviated from the reference phase is detected by the digital counter. This phase error data and the speed error data is processed and added by the digital filter circuit to control the PWM output. The phase and speed of the capstan, in turn, is controlled by this PWM output. The control signal of the capstan phase control in REC mode differs from that in PB mode. In REC mode, the control is performed by the DVCFG2 signal which is generated by dividing the frequencies of the reference signal (REF30P or CREF) and the CFG signal. In PB mode, it is performed by divided rising signal (DVCTL) of the reference signal (CAPREF30) and the playback control pulse (PB-CTL). The reference signal in record and playback modes are as follows. In record mode: 1/2 Vsync signal extracted from the video signal to be recorded In playback mode: Signal generated by dividing the PB-CTL signal (DVCTL) at its rising edge 28.9.2 Block Diagram Figure 28.34 shows the block diagram of the capstan phase error detector.

Write to CPPR1 first, and CPPR2 next. The preset data is referenced to H'80000*, and can be calculated from the following equation.

The reference values set in CPPR1 and CPPR2 are preset in the counter by the REF30P (CREF) signal or CAPREF30 signal, and counted up by the clock selected. The latching of the error data is performed by DVCTL or DVCFG2. The error data detected in the error data automatic transmission mode (CFEPS bit of DFUCR = 0) is sent to the digital filter circuit automatically. In software transmission mode (CFEPS bit of DFUCR = 1), the data written in CPER1 and CPER2 is sent to the digital filter circuit. The error data is signed binary. It takes a positive number (+) if the phase is behind the specified phase, a negative number (-) if in advance of the specified phase, or 0 if it had no phase error (revolving at the specified phase). Figures 28.35 and 28.36 show examples of operation to detect a capstan phase error. (a) Capstan phase error detection counter The capstan phase error detection counter stops the counter when overflow or latch occurred. At the same time, it generates an interrupt request (IRRCAP3), setting the overflow flag (CPOVF) if overflow occurred. Clear CPOVF by writing 0 after reading 1. If setting the flag and writing 0 take place simultaneously, the latter is nullified. Rev. 2.0, 11/00, page 716 of 1037 (b) Interrupt request IRRCAP3 is generated by the DVCTL or DVCFG2 signal latch and the overflow of the error detection counter.

Because of manufacturing tolerances, the physical distance between the video head and control head (the X-value: 79.244 mm) may vary from set to set, so when a tape that was recorded on a different set is played back, the phase of the reference signal may need to be adjusted. The adjustment can be made by a register setting. The same setting can adjust the rotational phase of the capstan motor to maintain positional alignment (tracking alignment) of the video head with the recorded tracks in autotracking, or when tracks that were recorded with an EP head are traced by a wider head. These tracking adjustments can be made by acquisition of the envelope signal by the A/D converter. 28.10.2 Block Diagram The adjustment circuit consists of a 10-bit counter clocked by the servo clock (s or s/2), and two down-counters with load register. Individual setting of X-value adjustment can be made by the X-value data register (XDR) and tracking adjustment by the TRK data register (TRDR). The reference signal clears the 10-bit counter and sets the load register value in the down-counter with two load registers. After the adjusted reference signal is generated, clock supply stops and the circuit halts until the next reference signal is input. The REF30 signal can be divided (by 2 to 4) as necessary.

Rev. 2.0, 11/00, page 722 of 1037 28.11 Digital Filters 28.11.1 Overview The digital filters required in servo control make extensive use of multiply-accumulate operations on signed integers (error data) and coefficients. A filter computation circuit (digital filter computation circuit) is provided in on-chip hardware to reduce the load on software, and to improve processing efficiency. Figure 28.38 shows a block diagram of the digital filter computation circuit configuration. The filter computation circuit includes a high-speed 24-bit x 16-bit multiplier-accumulator, an arithmetic buffer, and an I/O processor. The digital filter computations are carried out by the high-speed multiplier-accumulator. The arithmetic buffer stores coefficients and gain constants needed in the filter computations, which are referenced by the high-speed multiplieraccumulator. The I/O processor is activated by a frequency generator signal, and determines what operation is carried out. When activated, it reads the speed error and phase error from the speed and phase error detectors and sends them to the accumulator. When the filter computation is completed, the I/O processor reads the result from the accumulator and sends it to a 12-bit PWM. At this time, the accumulation result gain can be controlled.

This filter uses an IIR (Infinite Impulse Response) type digital filter (another type of the digital filter is FIR, i.e. Finite Impulse Response type). This digital filter circuit implements a lag-lead filter, as shown in figure 28.40.

The convergence of the computations becomes slow and servo retraction becomes deteriorating if a large error is input to the filter circuit when it is performing repeated computations. To prevent them from occurring, operate the filter (set constants A and B) after pulling in the speed and phase within a certain range of error, initialize Z-1 (set initial values in CZp, CZs, DZp, DZs)(see section 28.11.8, Initialization of Z-1), or use the error data limit function (see section regarding the error detector). 28.11.8 Initialization of Z -1 -1 Z can be initialized by its delay initialization register (CZp, CZs, DZp, DZs). Loading to Z is performed automatically by bits 4 and 3 of CFIC and DFIC (CZPON, CZSON, DZPON, -1 DZSON). Writing in register is always available, but loading in Z is not possible when the digital filter is performing calculation processing in relation to such register. In such a case, -1 loading to Z will be done the next time computation begins. Figure 28.42 shows the -1 initialization circuit of Z . -1 The delay initialization register sets 12-bit data. The MSB (bit 11) is a signed bit. Z has 24 bits for integers and 8 bits for decimals. Accordingly, the same value as the signed bits should be set -1 in the 13 bits on the MSB side of Z , and 0 in the entire decimal section.

It is activated at both edges of the HSW signal output by the headswitch timing generator. The head-switch timing generator also outputs a Vpulse signal containing the additional vertical sync pulse itself, and an Mlevel signal that defines the width of the additional vertical sync signal including the equalizing pulses. The additional V signal is output at a three-level output pin (Vpulse). Figure 28.43 shows the additional V signal control circuit. HSW timing generator Csync Vpulse signal Mlevel signal Sync detector OSCH Additional V pulse generator Additional V pulse Figure 28.43 Additional V Pulse Control Circuit (a) HSW timing generator This circuit generates signals that are synchronized with head switching. It should be programmed to generate the Mlevel and Vpulse signals at edges of the HSW signal (VideoFF). For details, see section 28.4, HSW (Head-switch) Timing Generator. (b) Sync detector This circuit detects pulses of the width specified by VTR or HTR from the signal input at the Csync pin and generates an internal horizontal sync signal (OSCH). The sync detector has an interpolation function, so OSCH has a regular period even if there are horizontal sync dropouts in the signal received at the pin.

If there is a lot of noise in the input sync signal (Csync), or a pulse is missing, OSCH will be a complementary pulse, and therefore an H pulse of the period set in HRTR and HPWR will be superimposed. In this case, there may be slight timing drift compared with the normal sync signal, depending on the HRTR and FPWR setting, with resultant discontinuity. If no sync signal is input, the additional V pulse is generated as a complementary pulse. Set the sync detector registers and activate the sync detector by manipulating the SYCT bit in the sync signal control register (SYNCR). See section 28.15.7, Sync Signal Detector Activation.

The PB-CTL signal is also sent to a duty discriminator in the CTL circuit that detects and records VISS, ASM, and VASS marks. A REC-CTL amplifier is included in the record circuits. Detection and recording whether the CTL pulse pattern is long or short can also be enabled to correspond to the wide-aspect. The following operating modes can be selected by settings in the CTL mode register: * Duty discrimination VISS detect, ASM detect, VASS detect, L/S bit pattern detect * CTL record VISS record, ASM record, VASS record, L/S bit pattern detect * Rewrite Trapezoid waveform generator Rev. 2.0, 11/00, page 746 of 1037 28.13.2 Block Diagram Figure 28.47 shows a block diagram of the CTL circuit.

The value to set in RCDR1 can be calculated from the transition timing T1 and the servo clock frequency s by the equation given below. See figure 28.60, REC-CTL Signal Generation Timing. Any transition timing can be set. However, the timing should be selected with attention to playback tracking compensation and the latch timing for phase control. RCDR1 = T1 x s/64 s is the servo clock frequency (= fOSC/2) in Hz, and T1 is the set timing (s). Note: 0 cannot be set to RCDR1. Set a value 1 or above.

Bits 15 to 12 are reserved and are not affected by write access. RCDR3 is initialized to H'F000 by a reset, and in standby mode, module stop mode, and CTL stop mode. At recording, the value to set in RCDR3 can be calculated from the transition timing T3 and the servo clock frequency s by the equation given below. The set value should be 30% of the duty when the RCDR3 is used for REC-CTL 1 pulse (long), and 67 to 70% when used for assemble mark. The set value must not exceed the value of REF30X. See figure 28.60, REC-CTL Signal Generation Timing. RCDR3 = T3 x s/64 s is the servo clock frequency (= fOSC/2) in Hz, and T3 is the set timing (s).

To clear the flag, write 0 after reading 1. Bit 1 BPF 0 1 Description Bit pattern (8-bit) is not detected Bit pattern (8-bit) is detected (Initial value) Bit 0: Duty I/O Register (DI/O) This flag has different functions for record and playback. In VISS detect mode, VASS detect mode, and ASM mark detect mode, this flag indicates the detection result. In VISS record or rewrite mode, this flag controls the write control circuit so as to write an index code, operating according to a control signal from the VISS control circuit. In VASS record or rewrite mode and ASM mark record mode, this flag is used for write control, one CTL pulse at a time. This bit can always be written to, but this does not affect the write control circuit in modes other than VISS record or rewrite, and ASM record. Rev. 2.0, 11/00, page 760 of 1037 VISS Detect Mode and VASS Detect Mode: The duty I/O flag indicates the result of duty discrimination. The duty I/O flag is 1 when the duty cycle of the PB-CTL signal is equal to or above 44% (a 0 pulse in the CTL signal). The duty I/O flag is 0 when the duty cycle of the PB-CTL signal is below 43% (a 1 pulse in the CTL signal). ASM Mark Detect Mode: The duty I/O flag indicates the result of duty discrimination. The duty I/O flag is 0 when the duty cycle of the PB-CTL signal is equal to or above 66% (when an ASM mark is detected). The duty I/O flag is 1 when the duty cycle of the PB-CTL signal is below 65% (when an ASM mark is not detected). VISS Record Mode and VISS Rewrite Mode: The duty I/O flag operates according to a control signal from the VISS control circuit, and controls the write control circuit so as to write an index code. The write timing is set in the REC-CTL duty data registers (RCDR1 to RCDR5). For VISS recording, registers RCDR1 to RCDR5 are set with reference to REF30X. For VISS rewrite, registers RCDR2 to RCDR5 are set with reference to the low-to-high transition of the previously recorded CTL signal, and the write is carried out through the trapezoid waveform generator. Set the duty timing for a 1 pulse (short) in RCDR2, for a 1 pulse (long) in RCDR3, for a 0 pulse (short) in RCDR4, and for a 0 pulse (long) in RCDR5. While an index code is being written, the value of the bit being written can be read by reading the duty I/O flag. If the CTL signal currently being written is a 0 pulse, the duty I/O flag will read 1. If the CTL signal currently being written is a 1 pulse, the duty I/O flag will read 0. VASS Record Mode and VASS Rewrite Mode: The duty I/O flag is used for write control, one CTL pulse at a time. The write timing is set in the REC-CTL duty data registers (RCDR1 to RCDR5). For VASS recording, registers RCDR1 to RCDR5 are set with reference to REF30X. For VASS rewrite, registers RCDR2 to RCDR5 are set with reference to the low-to-high transition of the previously recorded CTL signal, and the write is carried out through the trapezoid waveform generator. Set the duty timing for a 1 pulse (short) in RCDR2, for a 1 pulse (long) in RCDR3, for a 0 pulse (short) in RCDR4, and for a 0 pulse (long) in RCDR5. If 0 is written in the duty I/O flag, a CTL pulse will be written with a duty cycle set in RCDR2 and RCDR3, referenced to the immediately following REF30X. If 1 is written in the duty I/O flag, a CTL pulse will be written with a duty cycle set in RCDR4 and RCDR5, referenced to the immediately following REF30X. ASM Record Mode: The duty I/O flag is used for write control, one CTL pulse at a time. The write timing is set in the REC-CTL duty data registers (RCDR1 and RCDR3). If 0 is written in the duty I/O flag, a CTL pulse will be written with a duty cycle of 67% to 70% as set in RCDR3, referenced to the immediately following REF30X.

The bit pattern register (BTPR) is an 8-bit shift register which detects and records the bit pattern of the CTL pulses. If a CTL pulse is detected in PB or ASM mode, the register is shifted leftward at the rising edge of PB-CTL, and reflects the determined result of long/short on bit 0 (long pulse = 1, short pulse = 0). If the BPON bit is set to 1 in PB mode, the register starts detection of bit pattern immediately after the CTL pulse. To exit the bit pattern detection, set the BPON bit at 0. If 1 was written in the BPS bit when the bit pattern is being detected, the BPF bit is set at 1 when an 8-bit bit pattern was detected. If continuous detection of 8-bits is required, write 0 in the BPF bit, and then write 1 in the BPS bit. At the time of VISS detection, the bit pattern detection is disabled. Set the BPON bit to 0 at the time of VISS detection. In REC mode, the register records the long/short in the bit pattern set in BTPR. The pulse in record mode is determined always by bit 7 (LSP7) of BTPR. BTPR records one pulse, shifts leftward, and stores the data of bit 7 to bit 0. BTPR is initialized to H'FF by a reset, stand-by, module stop, or CTL stop. Rev. 2.0, 11/00, page 762 of 1037 28.13.6 Operation (a) CTL circuit operation As shown in figure 28.49, the CTL discrimination/record circuit is composed of a 16-bit up/down counter and 12-bit registers (x5). In playback (PB) mode, the 16-bit up/down counter counts on a s/4 clock when the PB-CTL pulse is high, and on a s/5 clock when low. In record (REC) or slow mode, this counter counts up on a s/8 clock when the pulse is high, and on a s/4 clock when low. This counter always counts up in record and slow modes.

If the CAPREF30 signal to be used for capstan phase control is always generated by XDR, the value of XDR must be overwritten when switching between PB and REC modes.

Figure 28.52 shows a block diagram of the CTL input section. A trivial CTL pulse signal is received from the CTL head, amplified by the input amplifier, reshaped into a square wave by the Schmitt amplifier, and sent to the servo circuits and timer L as the PB-CTL signal. Control the CTL input amplifier gain by bits 3 to 0 in the CTL gain control register (CTLGR) of the servo port.

Figure 28.52 Block Diagram of CTL Input Section Rev. 2.0, 11/00, page 766 of 1037 (1) CTL Detector If the CTL detector fails to detect a CTL pulse, it sets bit 1 of the CTL control register (CTCR) to high indicating that the pulse has not been detected. If a CTL pulse is detected after that, the bit is automatically cleared to 0. Duration used for determining detection or non-detection of the pulse depends on magnitude of phase shift of the last detected pulse from the reference phase (phase difference between REF30 and CTL signal). Typically, detection or non-detection is determined within 3 to 4 cycles of the reference period. If settings of the CTL gain control register are maintained in a table format, you can refer to it when the CTL detector failed to detect CTL pulses. From the table, you can control input sensitivity of the CTL according to the state of the UNCTL bit, thereby selecting an optimum CTL amplifier gain depending on the state of the pulse recorded. Figure 28.53 illustrates the concept of gain control for detecting the CTL input pulse. * V+TH (fixed) V-TH (fixed) * Note: * CTL input sensitivity is variable depending on CTL gain control register (CTLGR) setting.

In slow mode, if the falling edge is not detected within the specified time from rising edge detection, PB-CTL is forcibly shut down (slow reset). The time TFS (s) until the signal falls is the following interval after the rising edge of the internal CTL signal is detected: TFS = 16384 x 4 s (s = fOSC/2) When fOSC = 10 MHz, TFS = 13.1 ms.

In VISS or VASS detection, the duty I/O flag is set or cleared according to the result of duty discrimination. The duty I/O flag is set to 1 when the duty cycle of the PB-CTL signal is equal to or above 44%, and is cleared to 0 when the duty cycle is below 43%. In ASM detection, an ASM mark is recognized (and the duty I/O flag is cleared to 0) when the duty cycle is equal to or above 66%. When the duty cycle is below 65%, no ASM mark is recognized and the duty I/O flag is set to 1. The detection direction can be switched between forward and reverse by bit 5 (FW/RV) in the CTL mode register. A long or short pulse can be detected by comparing the REC-CTL duty data register (RCDR2 to RCDR5) and UP/DOWN counter. Long or short pulse is discriminated at PB-CTL signal falling. Discrimination result is stored in bit 0 (LSP0) of the bit pattern register (BTPR). At the same time, BTPR is shifted to the left. LSP0 indicates 0 when a short pulse is detected, and 1 when a long pulse is detected. Set the threshold value of a long/short pulse in RCDR2 to RCDR5. See (4), Detection of the Long/Short Pulse. Figure 28.55 shows the duty cycle of the PB-CTL signal.

A 44% duty cycle is discriminated by counting with the 16-bit up/down counter, using a s/4 clock for the up-count and a s/5 clock for the down-count. An up-count is performed when the PB-CTL signal is high, and a downcount when low. Long or short pulse is discriminated by comparing with RCDR2 to RCDR5.

If the pulse count detects any value set in the VISS interrupt setting bits (bits 5, 6 and 7 in the duty I/O register), an interrupt request is generated and the duty I/O flag is cleared to 0. At VISS record or rewrite, INDEX code is automatically written. INDEX code is composed of continuous 62-bit data with 0 pulse data at both edges. Examples of bit strings and the duty I/O flag at VISS detection/record are illustrated in figure 28.57.

Software can detect index sequences by reading the duty I/O flag at each CTL pulse. At each CTL pulse, the duty discriminator sends the result of duty discrimination to the duty I/O flag, and simultaneously generates an interrupt request. The duty I/O flag is cleared to 0 if the CTL pulse is a 1 (duty cycle below 43%), and is set to 1 if the CTL pulse is a 0 (duty cycle equal to or above 44%). The duty I/O flag is modified at each CTL pulse. It should be read by the interrupt-handling routine within the period of the PB-CTL signal. The VASS detection format is illustrated in figure 28.58.

If the duty discriminator detects that the duty cycle of the PB-CTL signal is 66% or higher, it generates an interrupt request, and simultaneously clears the duty I/O flag to 0. The duty I/O flag is updated at every CTL pulse. It should be read by the interrupt-handling routine within the period of the PB-CTL signal. Rev. 2.0, 11/00, page 773 of 1037 (4) Detection of the Long/Short Pulse The Long/Short pulse is detected in PB mode by the L/S determination based on the comparison of the REC-CTL duty registers (RCDR2 to RCDR5) with the up/down counter and the results of the duty I/O flag. The results of the determination are stored in bit 0 (LSP0) of the bit pattern register (BTPR) at the rising edge of PB-CTL, shifting BTPR leftward at the same time. RCDR2 to RCDR5 set the L/S thresholds for each of FWD/REV. Set to RCDR2 a threshold of 1 pulse L/S for FWD, to RCDR3 a threshold of 0 pulse L/S for FWD, to RCDR4 a threshold of 0 pulse L/S for REV, and to RCDR5 a threshold of 1 pulse L/S for REV. Figure 28.59 shows the detection of the Long/Short pulse. Also, the bit pattern of eight bits can be detected by BTPR. Check that an 8-bit detection has been done by bit 1 (BPF bit) of the duty I/O register, and then read BTPR.

Figure 28.59 Detection of Long/Short Pulse Rev. 2.0, 11/00, page 774 of 1037 28.13.9 CTL Output Section An on-chip control head amplifier is provided for writing the REC-CTL signal generated by the write control circuit onto the tape. The write control circuit controls the duty cycle of the REC-CTL signal in the writing of VISS and VASS sequences and ASM marks and the rewriting of VISS and VASS sequences. The duty cycle of the REC-CTL signal is set in REC-CTL duty data registers 1 to 5 (RCDR1 to RCDR5). Times calculated in terms of s (= fOSC/2) should be converted to appropriate data to be set in these registers. In VISS or VASS mode, set RCDR2 for a duty cycle of 25%0.5%, RCDR3 for a duty cycle of 30%0.5%, RCDR4 for a duty cycle of 57.50.5%, and RCDR5 for a duty cycle of 62.50.5%. When 1 is written in the duty I/O flag, the REC-CTL signal will be written on the tape with a 25%0.5% duty cycle when 0 is written in bit 7 (LSP7) in the bit pattern register (BTPR) and with a 300.5% duty cycle when 1 is written. Table 28.21 shows the relationship between the REC-CTL duty register and CTL outputs. In ASM mark write mode, set RCDR3 for a duty cycle of 67% to 70%. An ASM mark will be written when 0 is written in the duty I/O flag. An interrupt request is generated at the rise of the reference signal after one CTL pulse has been written. The reference signal is derived from the output signal (REF30X) of the X-value adjustment circuit, and has a period of one frame. Figure 28.60 shows the timings that generate the REC-CTL signal.

The counter is cleared on the rise of REF30X in record mode, and on the rise of PB-CTL in rewrite mode. The REC-CTL match detection is carried out by comparing the counter value with each RCDR value. RCDR1 to RCDR5 can be written to by software at all times. If RCDR is changed before the respective match detection is performed, match detection is performed using the new value. The value changed after match detection becomes valid on the rise of REF30X following the change. Figure 28.61 shows an example of RCDR change timing.

Time values T2 to T5 are referenced to the rise of PB-CTL. Figure 28.62 shows the rewrite waveform.

Rev. 2.0, 11/00, page 779 of 1037 28.14 Frequency Dividers 28.14.1 Overview On-chip frequency dividers are provided for the pulse signal picked up from the control track during playback (PB-CTL signal), and the pulse signal received from the capstan motor (CFG signal). An on-chip noise canceller is provided for the drum motor pulse signal (DFG signal). The CTL frequency divider generates a CTL divided control signal (DVCTL) from the PB-CTL signal, for use in capstan phase control during high-speed search, for example. The CFG frequency divider generates two divided signals (DVCFG for speed control and DVCFG2 for phase control) from the CFG signal. The DFG noise canceller is a circuit which considers a signal less than 2 as noise and masks it. 28.14.2 CTL Frequency Divider (1) Block Diagram Figure 28.63 shows a block diagram of the CTL frequency divider.

If a read is attempted, an undetermined value is read out. PB-CTL is divided by N at its rising edge. If the register value was 0, no division operation is performed, and the DVCTL signal with the same cycle with PB-CTL is output. It is initialized to H'00 by a reset or stand-by. Rev. 2.0, 11/00, page 782 of 1037 (3) Operation During playback, control pulses recorded on the tape are picked up by the control head and input to the CTL pin. The control pulse signal is amplified by a Schmitt amplifier, reshaped, then input to the CTL frequency divider as the PB-CTL signal. This circuit is employed when the control pulse (PB-CTL signal) is used for phase control of the capstan motor. The divided signal is sent as the DVCTL signal to the capstan phase system in the servo circuits, and the Timer R. The CTL frequency divider is an 8-bit reload timer consisting of a reload register and a down-counter. Frequency division is obtained by setting frequency-division data in bits 7 to 0 in the CTL frequency division register (CTLR), which is the reload register. When a frequency-division value is written in this reload register, it is also written into the downcounter. The down-counter is decremented on rising edges of the PB-CTL signal. Figure 28.64 shows examples of the PB-CTL signal and DVCTL waveforms.

The DVCFG2 signal is sent to the capstan speed error detector and the Timer L. The DVCFG2 circuit has no mask timer function. The frequency division counter for the DVCFG2 signal starts its division operation at the point data was written in CDIVR2. If synchronization is required for phase matching, for example, do it by writing in CDIVR2. If the DVTRG bit of the CDVC register was 0, the register synchronizes with the switching timing from PB (ASM) to REC. It is initialized to H'80 by a reset or stand-by together with the capstan frequency division register and the down counter.

If a read is attempted, an undetermined value is read out. CTMR is a reload register for the mask timer (down counter). Set in it the mask period of CFG. The mask period is determined by the clock specified by bits 1 and 0 of CDVC and the set value (N-1). If data is written in CTMR, it is written also in the mask timer at the same time. It is initialized to H'FF by a reset, stand-by or module stop. Mask period = N x clock cycle (3) Operation * Frequency divider The CFG pulses output from the capstan motor are sent to internal circuitry as the CFG signal via the zero-cross type comparator. The CFG signal, shaped into a rectangular waveform by a reshaping circuit, is divided by the CFG frequency dividers, and used in servo control. The rising edge or both edges of the CFG signal can be selected for the frequency divider. The CFG frequency dividers comprises a 7-bit frequency divider with a mask timer for capstan speed control (DVCFG signal generator) and a 7-bit frequency divider for capstan phase control (DVCFG2 signal generator). The DVCFG signal generator consists of a 7-bit reload register (CFG frequency division register1: CDIVR1), a 7-bit down-counter, and a 6-bit mask timer (with settable mask interval). Frequency division is performed by setting the frequency-division value in 7bit CDIVR1. When the frequency-division value is written in CDIVR1, it is also written in the down-counter. After frequency division of a CFG signal for which the edge has been selected, the signal is sent via the mask timer to the capstan speed error detector as the DVCFG signal. The DVCFG2 signal generator consists of a 7-bit reload register (CFG frequency division register 2: CDIVR2) and a 7-bit down-counter. The 7-bit frequency divider does not have a mask timer. Frequency division is performed by setting the frequency-division value in CDIVR2. When the frequency-division value is written in CDIVR2, it is also written in the down-counter. After frequency division of a CFG signal for which the edge has been selected, the signal is sent to the capstan speed error detector and the Timer L as the DVCFG2 signal. Frequency division starts when the frequency-division value is written. Rev. 2.0, 11/00, page 789 of 1037 When the DVTRG bit in the CDVC register is set to 0, reloading is executed with the switchover timing from PB (ASM) mode to REC mode. To switch from REF30 to CREF, change the settings of bit 4 (CR/RF bit) in the capstan phase error detection control register (CPGCR). If synchronization is necessary for phase control, this can be provided by writing the frequency-division value in CDIVR2. The down-counters are decremented on rising edges of the CFG signal when the CRF bit is 0 in the DVCFG control register (CDVC), and on both edges when the CRF bit is 1. Figure 28.66 shows examples of CFG frequency division waveforms.

The mask timer is used for masking the DVCFG signal intended for controlling the capstan speeds. The capstan mask timer prevents edge detection to be carried out for an unnecessarily long duration by masking the edge detection for a certain period. The above trouble can result from abnormal revolution (runout) of the capstan motor because its revolution has to cover a wide range speeds from the slow/still up to the high speed search. The capstan mask timer is started by output of a pulse edge in the divided CFG signal (DVCFG). While the timer is running, a mask signal disables the output of further DVCFG pulses. The mask signal is shown in Figure 28.67. The mask timer status can be recognized by reading the CMK flag in the DVCFG control register (CDVC).

It detects the horizontal and vertical sync signals by setting threshold in the register and based on the servo clock (s = fosc/2). Noise masking is possible during the detection of the horizontal sync signals, and if any Hsync is missing, it can be supplemented. Also, if total volume of the noise detected in one frame of Csync amounted over a specified volume, the detector generates a noise detection interrupt. Note: This circuit detects a pulse with a specific width set by the threshold register. It does not classify or restore the sync signal to a formal one.

Assumed that the set values in the VTHR register were VVTH and HVTH, (VVTH-1) x 2/s > Hpuls (HVTH-2) x 2/s Hpuls/2 < (HVTH-1) ) x 2/s Where, Hpuls is pulse width (s) of the horizontal sync signal, and s is servo clock (fosc/2). Thus, if s = 5 MHz, NTSC system is used, (VVTH-1) x 0.4s > 4.7s VVTH H'D (HVTH-2) x 0.4s 2.35s < (HVTH-1) x 0.4s HVTH H'7 Note: This circuits detects the pulse with the width set in the VTHR register.

((Value of HRTR7 to HRTR0) + 1) x 2/s = TH where, TH is the cycle of the horizontal sync signal (s), and s is the servo clock (fosc/2). Whether the horizontal sync signal exists or not is determined one clock before the supplementary pulse is generated. Accordingly, set to HRTR7 to HRTR0 a value obtained from the equation shown above plus one. Also, HRTR7 to HRTR0 set the noise mask period. If the horizontal sync signal had the normal pulses, it is masked in the mask period. The start and end of the mask period are computed frm the rising edge of OSCH and SEPH, respectively.

It is initialized to H'00 by a reset, stand-by or module stop. The noise detector takes counts of the drop-outs of the horizontal sync signals and the noises within the pulses, and if they amount to a count greater than four times of the value set in NDR7 to NDR0, the detector sets the NOIS flag in the sync signal control register (SYNCR). Set the noise detection level at 1/4 of the noise counts in one frame. The noise counter is cleared whenever Vsync was detected twice.

Set the noise detection window with HWR of about 1/4 of the horizontal sync signal, and the pulse with equal High and Low periods will be obtained. (1) Example of Setting Assumed that a supplemented pulse is set when fosc = 10MHz under the conditions s = 5MHz, NTSC:TH = 63.6 (s) and Hpuls = 4.7 (s), the set values of the supplemented pulse timing (HRTR7-0), supplemented pulse width (HPWR3-0) and noise detection window timing (NWR5-0) are expressed by the following equations. (Value of HRTR7-0) x 2/s = TH ((Value of HPWR3-0) + 1) x 2/s = Hpuls ((Value of NWR5-0) + 1) x 2/s = 1/4 x TH Where, TH is the cycle of the horizontal sync signal (s), Hpuls is the pulse width of the horizontal sync signal (s) and s is the servo clock (Hz) (fosc/2). Accordingly, (Value of HRTR7 to HRTR0) x 0.4 (s) = 63.6 (s) HRTR7-0=H'9F ((Value of HPWR3 to HPWR0) + 1) x 0.4 (s) = 4.7 (s) HRTR3-0=H'B ((Value of NWR5 to NWR0) + 1) x 0.4 (s) = 16 (s) NWR5-0=H'27 Also, the noise mask period is computed as follows.

The noise counter takes counts of the irregular pulses during the High period of the noise detection window and the chips and drop-outs of the horizontal sync signal pulses during the Low period. Also, it counts more than one irregular pulses as one. The noise counter is cleared at every frame (Vsync is detected twice). The equivalent pulse contained in 9H of the vertical sync signal is counted also as an irregular pulse. It sets the noise detection flag (NOIS) in the sync signal control register (SYNCR) at 1 if the count of the irregular pulses + the count of the pulse chips and drop-outs of the horizontal sync signal > 4 x (value of NDR7 to NDR0). See section 28.15.5 (7), Sync Signal Control Register (SYNCR) for the NOIS bit. Figure 28.76 shows the operation of the noise detection.

The signal given to the detector is the polarity pulse assigned by the SYCT bit of the sync signal control register (SYNCR). The detector starts operation even if this pulse was a noise pulse with a width short of the regular width. The minimum pulse width which can activate the detector is not constant depending on the internal operation of the input circuit. Accordingly, if the assured activation of the detector is required, input a pulse with a width greater than 4/s (s = fosc/2 (Hz)). In such a case, care is required to noise, etc., because even a pulse with a width smaller than 4/s may cause activation.

A.4 Number of Execution States This section explains execution state and how to calculate the number of execution states for each instruction of the H8S/2194 CPU. Table A.5 indicates number of cycles of instruction fetch and data read/write during instruction execution, and table A.4 indicates number of states required for each instruction size. The number of execution states can be obtained from the equation below.

If the power supply voltages cannot rise and fall simultaneously, power supply operations should be carried out in this order. At power-on, wait until the microcomputer section power supply (VCC) has risen to the prescribed voltage, then raise the other analog power supplies. At power-down, drop the analog power supplies first, followed by the microcomputer section power supply (VCC). When powering up and down, ensure that the voltage applied to the pins does not exceed the respective power supply voltage. VCC, AVCC SVCC Vin Vin VCC, AVCC SVCC VCC AVCC SVCC Vin : Microcomputer section power supply voltage : A/D converter power supply voltage : Servo section power supply voltage : Pin applied voltage Figure E.1 Power Supply Rise and Fall Order In power-down modes (except sleep mode), the analog power supplies can be turned off to reduce current dissipation. When the microcomputer section power supply (VCC) is dropped to the backup voltage in a power-down mode, the order shown in figure E.2 should be followed. Make sure that the voltage applied to the pins does not exceed the respective power supply voltage. The A/D converter power supply (AVCC) should be set to the same potential as the microcomputer section power supply (VCC). In all power-down modes except sleep mode, AVCC is turned off inside the device. At this time, the AVCC current dissipation is defined as AISTOP.

COMP is an input pin, and the other two are output pins. When the switching circuit for four-head special-effects playback is not used, the related pins should be handled as shown below.
