PORT1 is used as the 16-bit address bus (A) in demultiplexed bus modes and also after switching from a demultiplexed bus mode to a multiplexed bus mode. Reset Input with Schmitt-Trigger characteristics. A low level at this pin for a specified duration while the oscillator is running resets the device. An internal pullup resistor permits power-on reset using only a capacitor connected to VSS. Internal Reset Indication Output. This pin is set to a low level when the part is executing either a hardware-, a software- or a watchdog timer reset. RSTOUT remains low until the EINIT (end of initialization) instruction is executed. Non-Maskable Interrupt Input. A high to low transition at this pin causes the CPU to vector to the NMI trap routine. When the PWRDN (power down) instruction is executed, the NMI pin must be low in order to force the ST10R65 to go into power down mode. If NMI is high, when PWRDN is executed, the part will continue to run in normal mode. If not used, pin NMI should be pulled high externally.

4-Memory Organization

Memory Organization
The memory space of the ST10F163 is configured in a Von-Neumann architecture. Code memory, data memory, registers and I/O ports are organized within the same linear address space which includes 16 MBytes. The entire memory space can be accessed bytewise or wordwise. Particular portions of the on-chip memory have additionally been made directly bit addressable. 1 KByte of on-chip RAM is provided as a storage for user defined variables, for the system stack, general purpose register banks and even for code. A register bank can consist of up to 16 wordwide (R0 to R15) and/or bytewide (RL0, RH0, ..., RL7, RH7) General Purpose Registers (GPRs). 1024 bytes (2 * 512 bytes) of the address space are reserved for the Special Function Register areas (SFR space and ESFR space). SFRs are wordwide registers which are used for controlling and monitoring functions of the different on-chip units. Unused SFR addresses are reserved for other/future members of the ST10 family. In order to meet the needs of system designs where more memory is required than is provided on chip, up to 16 MBytes of external RAM and/or ROM can be connected to the microcontroller.

Flash Memory
The ST10F163 provides 128KBytes of on-chip, electrically erasable and re-programmable Flash EPROM. The flash memory is organized in 32 bit wide blocks. This allows double word instructions to be fetched in one machine cycle. The flash memory can be used for both code and data storage. The flash memory is organized into four banks of sizes 8K, 24K, 48K and 48Kbytes (table 2). Each of these banks can be erased independently. This prevents unnecessary erasing of the whole flash memory when only a partial erasing is required.
Bank 0 1 2 3 Addresses (Segment 0) 000000h to 001FFFh 002000h to 007FFFh 018000h to 023FFFh 024000h to 02FFFFh Addresses (Segment 1) 010000h to 011FFFh 012000h to 017FFFh 018000h to 023FFFh 024000h to 02FFFFh Size (bytes) 8K 24K 48K 48K
Table 2 FLASH memory bank organisation Typical timing characteristics give 80s for word or double word programming and 800 ms for block erasing, at 25mhz system clock. the flash memory has a typical endurance of 1000 erasing/programming cycles. the flash memory can be programmed, either in a programming board, or in the target system. the code to program or erase the flash memory is executed from an external memory or from the on-chip ram, but not from the flash memory itself. as a flexible and cost-saving alternative, the on-chip bootstrap loader may be used to load and start the programming code. the following considerations must be taken into account for programming or erasing `on-line' in the target system:
* While operations are in progress, the flash memory can not be accessed as usual, no
branch can be made to the flash memory and no data reads can be taken from the flash memory.
* If the two first blocks (8KB + 24KB) of the flash memory are mapped to segment 0, no
interrupt or hardware trap must occur during programming or erasing, as this would require a `forbidden' branch to the flash memory. A flash memory protection option, when activated, prevents view access to the contents of the ROM and the on-chip RAM, code operation from within the flash memory continues as normal. During the initialization phase, the first two blocks of the flash memory (8KB + 24KB) can be mapped to segment 0 (addresses 00000h to 07FFFh), or to segment 1 (addresses 10000h to 17FFFh). This makes it possible to use external memory for additional system flexibility.

5.1
Programming/erasing with ST Embedded Algorithm Kernel
In order to secure flash programming and erasing operations, and also to simplify the software development for programming and erasing the Flash, the ST10F163 Flash is programmed or erased by executing a specific sequence of instructions (called `Unlock Sequence') with command and parameters loaded into GPRs. The Unlock Sequence' invokes embedded kernel routines that checks the validity of the parameters provided by the user, and decodes the command (programming or erasing) and executes it. When performing a programming command, the Embedded Algorithm Kernel automatically times the program pulse widths (taking in account the CPU period provided as a parameter by the user) and verifies proper cell programming. When performing an erasing command, the Embedded Algorithm Kernel automatically pre-programs the bank to be erased if it is not already programmed. During erase, the Embedded Algorithm Kernel automatically times the erase pulse widths (taking in account the CPU period provided as a parameter by the user) and verifies proper cell erasing. To start a program/erase operation, the user's application must perform an `Unlock Sequence' to trigger the flash ST Embedded Algorithms Kernel (STEAK). Before using STEAK, proper parameters must be assigned through the R0-R4 registers. The R0 register is the command register. The other registers handle the address and data to be programmed or sector to be erased. Table 3 defines the command sequence. A definition of the codes used in Table 3 is given in Table 4.

The value D = (EndAddOff - BegAddOff) must be: 0 <= D < 16384 (ie. up to one page (16 KBytes) can be written in the flash with one multi-word programming command). Start address for the source data (block) to be programmed. This address uses implicitly the data paging mechanism of the CPU. SourceAdd value must respect the rules: SourceAdd + (EndAddOff - BegAddOff) < 16384. Page 0 and 1 can NOT be used for source data if SYSCON bit ROMS1 = `1' Note: source data can be located in flash (In pages 0, 1, 6, 7, 8, 9, 10 or 11 if bit ROMS1 = `0', or in pages 4, 5, 6, 7, 8, 9, 10 or 11 if bit ROMS1 = `1'.

For easier coding, the standard data paging addressing scheme is overridden for the two MOV instruction of the Flash Trigger Sequence (EXTS instruction).

Flash memory configuration
The default memory configuration is determined by the state of the EA pin at reset. This value is stored in the Internal ROM enable bit: ROMEN of the SYSCON Register. When ROMEN=0, the internal ROM is disabled and external ROM is used for start-up control. The first 32KBytes of the flash memory area must be re-mapped to segment 1, to enable their later use. This is done by setting the ROMS1 bit of SYSCON to 0. This is done by the externally supplied program, before the execution of the EINIT instruction. If program execution starts from external memory, but access to the flash memory (re-mapped to Bank 1) is required later, one of the following values has to be written to the SYSCON register, before the end of initialization:

(ROMS1=1,SGTDIS=0)
5-Flash Memory
* If flash is to be mapped to segment 0: xxx000xxxxxxxxxxb
(ROMS1=0,SGTDIS=0) All other parts of the flash memory (addresses 18000h - 1FFFFh) remain unaffected. The SGTDIS Segmentation Disable/Enable must be set to 0 so that the 64KBytes of on-chip memory can be used in addition to the external boot memory. The correct procedure for changing the segmentation registers must be observed, to prevent unwanted trap conditions:
* Instructions that configure the internal memory must only be executed from external
memory or from the internal RAM.
* Whenever the internal memory is disabled, enabled or re-mapped, the DPPs must be
explicitly (re)loaded to enable correct data accesses to the internal memory and/or external memory.
5.3
Flash protection
The flash protection mode, prevents the reading of data operands in the flash memory by anything but a program executed from the flash memory itself. Flash protection mode permits program branches from, or into the flash memory, but does not permit erasing and programming of the flash memory. Flash protection is controlled by the Protection UPROM Programming Bit (UPROG). UPROG is a 'hidden' one-time programmable bit. It is only accessible in a special mode, entered, for example, via a flash EPROM programming board. If UPROG is set to `1', flash protection is active after reset. By default flash protection is disabled (UPROG=0). For deactivation of flash protection, where the flash memory has to be reprogrammed with updated program/variables, a zero value must be written at every even address in the active address space of the flash memory. This write can only be done by an instruction executed from the internal flash memory itself, e.g. MOV FLASH,ZEROS

6-External Bus Controller
ST10F163 Data Sheet
6
External Bus Controller
All of the external memory accesses are performed by a particular on-chip External Bus Controller (EBC). It can be programmed either to Single Chip Mode when no external memory is required, or to one of four different external memory access modes:
* 16-/18-/20-/24-bit Addresses, 16-bit Data, Demultiplexed * 16-/18-/20-/24-bit Addresses, 16-bit Data, Multiplexed * 16-/18-/20-/24-bit Addresses, 8-bit Data, Multiplexed * 16-/18-/20-/24-bit Addresses, 8-bit Data, Demultiplexed
In the demultiplexed bus modes, addresses are output on PORT1 and data is input/output on PORT0 or P0L, respectively. In the multiplexed bus modes both addresses and data use PORT0 for input/output. Important timing characteristics of the external bus interface (Memory Cycle Time, Memory Tri-State Time, Length of ALE and Read Write Delay) have been made programmable. This gives the choice of a wide range of different types of memories and external peripherals. In addition, up to 4 independent address windows may be defined (via register pairs ADDRSELx / BUSCONx). This gives access to different resources with different bus characteristics. These address windows are arranged hierarchically where BUSCON4 overrides BUSCON3 and BUSCON2 overrides BUSCON1. All accesses to locations not covered by these 4 address windows are controlled by BUSCON0. Up to 5 external CS signals (4 windows plus default) can be generated in order to save external glue logic. Access to very slow memories is supported via a particular `Ready' function. A HOLD/HLDA protocol is available for bus arbitration so that external resources can be shared with other bus masters. The bus arbitration is enabled by setting bit HLDEN in register SYSCON. After setting HLDEN once, pins P6.7...P6.5 (BREQ, HLDA, HOLD) are automatically controlled by the EBC. In Master Mode (default after reset) the HLDA pin is an output. By setting bit DP6.7 to'1' the Slave Mode is selected where pin HLDA is switched to input. This allows to directly connect the slave controller to another master controller without glue logic. For applications which require less than 16 MBytes of external memory space, this address space can be restricted to 1 MByte, 256 KByte or to 64 KByte. In this case Port 4 outputs four, two or no address lines at all. If an address space of 16 MBytes is used, it outputs all 8 address lines.
Note
When the on-chip SSP Module is to be used the segment address output on Port 4 must be limited to 4 bits (i.e. A19...A16) in order to enable the alternate function of the SSP interface pins.

The position of the CSx lines can be changed by setting the CSCFG bit in the SYSCON register. By default the CSx lines change half a CPU clock cycle after the rising edge of ALE (20ns @ fCPU = 25 MHz). With the CSCFG bit set (section Figure 7), the CSx lines change with the rising edge of ALE. In this case, the CSx lines and address lines change at the same time.

Figure 5 CPU block diagram The main core of the CPU consists of a 4-stage instruction pipeline, a 16-bit arithmetic and logic unit (ALU) and dedicated SFRs. Additional hardware has been added for a separate multiply and divide unit, a bit-mask generator and a barrel shifter. Based on these hardware provisions, most of the ST10F163's instructions can be executed in one machine cycle. This requires 80ns at 25MHz CPU clock. For example, shift and rotate instructions are always processed in one machine cycle independent of the number of bits to be shifted. All multiple-cycle instructions have been optimized for speed: branches in 2 cycles, a 16 x 16 bit multiplication in 5 cycles and a 32-/16 bit division in 10 cycles. The `Jump Cache' pipeline optimization, reduces the execution time of repeatedly performed jumps in a loop, from 2 cycles to 1 cycle. The CPU includes an actual register context. This consists of up to 16 wordwide GPRs physically allocated in the on-chip RAM area. A Context Pointer (CP) register determines the base address of the active register bank to be accessed by the CPU. The number of register banks is only restricted by the available internal RAM space. For easy parameter passing, one register bank may overlap others. A system stack of up to 1024 bytes is provided as a storage for temporary data. The system stack is allocated in the on-chip RAM area, and it is accessed by the CPU via the stack

pointer (SP) register. Two separate SFRs, STKOV and STKUN, are implicitly compared against the stack pointer value upon each stack access for the detection of a stack overflow or underflow. The basic instruction length is either 2 or 4 bytes. Possible operand types are bits, bytes and words. A variety of direct, indirect or immediate addressing modes exist.

Interrupt System
With an interrupt response time from 200 ns to 480ns (in the case of internal program execution), the ST10F163 reacts quickly to the occurrence of non-deterministic events. The architecture of the ST10F163 supports several mechanisms for fast and flexible response to service requests that can be generated from various sources internal or external to the microcontroller. Any of these interrupt requests can be programmed to being serviced by the Interrupt Controller or by the Peripheral Event Controller (PEC). In a standard interrupt service, program execution is suspended and a branch to the interrupt vector table is performed. For a PEC service, just one cycle is `stolen' from the current CPU activity. A PEC service is a single byte or word data transfer between any two memory locations with an additional increment of either the PEC source or the destination pointer. An individual PEC transfer counter is decremented for each PEC service, except for the continuous transfer mode. When this counter reaches zero, a standard interrupt is performed to the corresponding source related vector location. PEC services are suited to, for example, the transmission or reception of blocks of data. The ST10F163 has 8 PEC channels, each of which offers fast interrupt-driven data transfer capabilities. A separate control register which contains an interrupt request flag, an interrupt enable flag and an interrupt priority bitfield, exists for each of the possible interrupt sources. Via its related register, each source can be programmed to one of sixteen interrupt priority levels. Once having been accepted by the CPU, an interrupt service can only be interrupted by a higher prioritized service request. For the standard interrupt processing, each of the possible interrupt sources has a dedicated vector location. Fast external interrupt inputs are provided to service external interrupts with high precision requirements. These fast interrupt inputs, feature programmable edge detection (rising edge, falling edge or both edges). Software interrupts are supported by means of the `TRAP' instruction in combination with an individual trap (interrupt) number.

immediate non-maskable system reaction which is similar to a standard interrupt service (branching to a dedicated vector table location). The occurrence of a hardware trap is additionally signified by an individual bit in the trap flag register (TFR). Except when another higher prioritized trap service is in progress, a hardware trap will interrupt any actual program execution. In turn, hardware trap services can normally not be interrupted by standard or PEC interrupts. Table 7 shows all of the possible exceptions or error conditions that can arise during run time.

General Purpose Timer (GPT) Unit
The GPT unit is a flexible multifunctional timer/counter structure which is used for time related tasks such as event timing and counting, pulse width and duty cycle measurements, pulse generation, or pulse multiplication. The GPT unit contains five 16-bit timers organized into two separate modules GPT1 and GPT2. Each timer in each module may operate independently in several different modes, or may be concatenated with another timer of the same module.
9.1
GPT1
Each of the three timers T2, T3, T4 of module GPT1 can be configured individually for one of three basic modes of operation: timer, gated timer, and counter mode. In Timer Mode, the input clock for a timer is derived from the CPU clock, divided by a programmable pre-scaler. In counter Mode a timer is clocked in reference to external events. Gated timer mode supports pulse width or duty cycle measurement, where the operation of a timer is controlled by the `gate' level on an external input pin. Each timer has one associated port pin (TxIN) which serves as gate or clock input. Table 8 GPT1 timer input frequencies, resolution and periods lists the timer input frequencies, resolution and periods for each pre-scaler option at 25 MHz CPU clock.

Table 8 GPT1 timer input frequencies, resolution and periods The count direction (up/down) for each timer is programmable by software or is altered dynamically by an external signal on a port pin (TxEUD). For example, this facilitates position tracking. Timer T3 has output toggle latches (TxOTL) which changes state on each timer over-flow/ underflow. The state of this latch may be output on port pins (TxOUT) e. g. for time out

monitoring of external hardware components, or may be used internally to clock timers T2 and T4 for measuring long time periods with high resolution. In addition to their basic operating modes, timers T2 and T4 may be configured as reload or capture registers for timer T3. When used as reload or capture registers, timers T2 and T4 are stopped. The content of timer T3 is captured into T2 or T4 in response to a signal at their associated input pins (TxIN). Timer T3 is reloaded with the contents of T2 or T4, triggered, either by an external signal or by a selectable state transition of its toggle latch, T3OTL. When both T2 and T4 are configured to alternately reload T3 on opposite state transitions of T3OTL with the low and high times of a PWM signal, this signal can be constantly generated without software intervention.
9.2
GPT2
The GPT2 module provides precise event control and time measurement. It includes two timers (T5, T6) and a capture/reload register (CAPREL). Both timers can be clocked with an input clock which is derived from the CPU clock via a programmable prescaler or with external signals. The count direction (up/down) for each timer is programmable by software or may additionally be altered dynamically by an external signal on a port pin (TxEUD). Concatenation of the timers is supported via the output toggle latch (T6OTL) of timer T6 which changes its state on each timer overflow/underflow. The state of this latch may be used to clock timer T5, or it may be output on a port pin (T6OUT). The overflows/underflows of timer T6 can additionally be used to clock the CAPCOM timers T0 or T1, and to cause a reload from the CAPREL register. The CAPREL register may capture the contents of timer T5 based on an external signal transition on the corresponding port pin (CAPIN), and timer T5 may optionally be cleared after the capture procedure. This allows absolute time differences to be measured or pulse multiplication to be performed without software overhead. Table 9 GPT2 timer input frequencies, resolution and period lists the timer input frequencies, resolution and periods for each pre-scaler option at 25 MHz CPU clock.

10-Parallel Ports
10 Parallel Ports
The ST10F163 provides up to 77 I/O lines which are organized into six input/output ports and one input port. All port lines are bit-addressable, and all input/output lines are individually (bit-wise) programmable as, either inputs or outputs via direction registers. The I/ O ports are true bidirectional ports which are switched to high impedance state when configured as inputs. The output drivers of three I/O ports can be configured (pin by pin) for push/pull operation or open-drain operation via control registers. During the internal reset, all port pins are configured as inputs. All port lines have associated, programmable, alternate input or output functions. PORT0 and PORT1 may be used as address and data lines when accessing external memory. Port 4 outputs the additional segment address bits A23/19/17...A16 in systems where segmentation is enabled to access more than 64 KBytes of memory. Port 6 provides optional bus arbitration signals (BREQ, HLDA, HOLD) and chip select signals. Port 3 includes alternate functions of timers, serial interfaces, the optional bus control signal BHE and the system clock output (CLKOUT). Port 5 is used for timer control signals. All port lines that are not used for these alternate functions may be used as general purpose I/O lines.
11 Serial Channels
Serial communication with other microcontrollers, processors, terminals or external peripheral components is provided by two serial interfaces, an Asynchronous/Synchronous Serial Channel (ASC0) and a Synchronous Serial Port (SSP). ASC0: The table below shows the baud rates for the asynchronous/synchronous serial channel. A dedicated baud rate generator is used to set up all standard baud rates without oscillator tuning. 3 separate interrupt vectors are provided for transmission, reception, and erroneous reception. In asynchronous mode, 8- or 9-bit data frames are transmitted or received, preceded by a start bit and terminated by one or two stop bits. For multiprocessor communication, a mechanism to distinguish address from data bytes has been included (8-bit data + wake up bit mode). In synchronous mode, the ASC0 transmits or receives bytes (8 bits) synchronously to a shift clock which is generated by the ASC0. The ASC0 always shifts the LSB first. A loop back option is available for testing purposes. A number of optional hardware error detection capabilities have been included to increase the reliability of data transfers. A parity bit can automatically be generated on transmission or be checked on reception. Framing error detection allows to recognize data frames with missing stop bits. An overrun error will be generated, if the last character received has not

12-Watchdog Timer
SSP: The Synchronous Serial Port provides high-speed serial communication with external slave devices such as EEPROM. The SSP transmits 1...3 bytes or receives 1 byte after sending 1...3 bytes synchronously to a shift clock which is generated by the SSP. The SSP can start shifting with the LSB or with the MSB and is used to select shifting and latching clock edges as well as the clock polarity. Up to two chip select lines may be activated in order to direct data transfers to one or both of two peripheral devices.

12 Watchdog Timer
The Watchdog Timer is a fail-safe mechanism which the maximum malfunction time of the controller The Watchdog Timer is always enabled after a reset of the chip, and can only be disabled in the time interval until the EINIT (end of initialization) instruction has been executed. In this way the chip's start-up procedure is always monitored. The software must be designed to service the Watchdog Timer before it overflows. If, due to hardware or software related failures, the software fails to do so, the Watchdog Timer overflows and generates an internal hardware reset and pulls the RSTOUT pin low in order to allow external hardware components to be reset. The Watchdog Timer is a 16-bit timer, clocked with the system clock divided either by 2 or by 128. The high byte of the Watchdog Timer register can be set to a pre-specified reload value (stored in WDTREL) in order to allow further variation of the monitored time interval. Each time it is serviced by the application software, the high byte of the Watchdog Timer is reloaded. The table below shows the watchdog time range which for a 25MHz CPU clock. Some numbers are rounded to 3 significant digits.

Note
For security, rewrite WDTCON each time before the watchdog timer is serviced.
13 Oscillator Watchdog (OWD)
The Oscillator Watchdog (OWD) monitors the clock signal generated by the on-chip oscillator (either with a crystal or via external clock drive). For this operation the PLL provides a clock signal to supervise transitions on the oscillator clock. This PLL clock is independent from the XTAL1 clock. When the expected oscillator clock transitions are missing, the OWD activates the PLL Unlock/OWD interrupt node and supplies the CPU with the PLL clock signal. Under these circumstances the PLL will oscillate with its basic frequency. A low level on pin OWE disables the OWD's interrupt output, so that the clock signal is derived from the oscillator clock. The CPU clock source is only switched back to the oscillator clock after a hardware reset. When the direct-drive, or direct-drive-with-prescaler clock option is selected, an oscillator watchdog is implemented. This provides a fail-safe mechanism in the case of a loss of external clock. After reset, the Oscillator Watchdog is enabled by default. To disable the OWD, the bit OWDDIS (bit 4 of SYSCON register) must be set. When the OWD is enabled, PLL runs on free-running frequency, and increments the Oscillator Watchdog counter. On each transition of XTAL1 pin, the Oscillator Watchdog is cleared. If an external clock failure occurs, then the Oscillator Watchdog counter overflows (after 16 PLL clock cycles). The CPU clock signal is switched to the PLL free-running clock signal, and the Oscillator Watchdog Interrupt Request (XP3INT) is flagged. The CPU clock will not switch back to the external clock even if a valid external clock exits on XTAL1 pin. Only a hardware reset can switch the CPU clock source back to direct clock input. When the OWD is disabled, the CPU clock is always fed from the oscillator input and the PLL is switched off to decrease power supply current.

1. ST10F163 pins are equipped with Low-Noise output drivers, which significantly improve the device's EMI performance. These Low-Noise drivers deliver their maximum current only until the respective target output level is reached. After that, the output current is reduced. This results in an increased impedance of the driver, which attenuates electrical noise from the connected PCB tracks. The current specified in column "Test Conditions" is delivered in any case. 2. This specification is not valid for outputs which are switched to open drain mode. In this case the respective output will float and the voltage results from the external circuitry. 3. Not 100% tested, guaranteed by design characterization. 4. This specification is only valid during Reset, or during Hold- or Adapt-mode. Port 6 pins are only affected, if they are used for CS output and the open drain function is not enabled. 5. The maximum current may be drawn while the respective signal line remains inactive. 6. The minimum current must be drawn in order to drive the respective signal line active. 7. The power supply current is a function of the operating frequency. This dependency is illustrated in the figure below. These parameters are tested at VDDmax and 25 MHz CPU clock with all outputs disconnected and all inputs at VIL or VIH. The chip is configured with a demux 16-bit bus, direct clock drive, 5 chip select lines and 2 segment address lines, EA pin is low during reset. After reset, Port0 is driven with the value `00CCh' that produces infinite execution of NOP instruction with 15 wait-state, R/W delay, memory tristate waitstate, normal ALE.

16.4.2 Definition of internal timing
The internal operation of the ST10F163 is controlled by the internal CPU clock fCPU. Both edges of the CPU clock can trigger internal (e.g. pipeline) or external (e.g. bus cycles) operations. The specification of the external timing (AC Characteristics) therefore depends on the time between two consecutive edges of the CPU clock, called "TCL" (see figure below). The CPU clock signal can be generated by different mechanisms. The duration of TCLs and their variation (and also the derived external timing) depends on the used mechanism to

Notes Default configuration
1. The external clock input range refers to a CPU clock range of 1...25 MHz. 2. The maximum depends on the duty cycle of the external clock signal. 3. The maximum input frequency is 25 MHz when using an external crystal with the internal oscillator; providing that internal serial resistance of the crystal is less than 40 . However, higher frequency can be applied with an external clock source, but in this case, the input clock signal must reach the defined levels VIL and VIH2.
16.4.4 Prescaler operation
When pins P0.15-13 (P0H.7-5) equal '001' during reset, the CPU clock is derived from the internal oscillator (input clock signal) by a 2:1 prescaler. The frequency of fCPU is half the frequency of fXTAL and the high and low time of fCPU (i.e. the duration of an individual TCL) is defined by the period of the input clock fXTAL. The timings listed in the AC Characteristics that refer to TCLs therefore can be calculated using the period of fXTAL for any TCL. Note that if the bit OWDDIS in SYSCON register is cleared, the PLL is running on its free-running frequency and delivers the clock signal for the Oscillator Watchdog. If bit OWDDIS is set, then the PLL is switched off.

16.4.5 Direct drive
When pins P0.15-13 (P0H.7-5) equal'011' during reset the on-chip phase locked loop is disabled and the CPU clock is directly driven from the internal oscillator with the input clock signal. The frequency of fCPU directly follows the frequency of fXTAL so the high and low time of fCPU (i.e. the duration of an individual TCL) is defined by the duty cycle of the input clock fXTAL. The timings listed below that refer to TCLs therefore must be calculated using the minimum TCL that is possible under the respective circumstances. This minimum value can be calculated by the following formula:
TCL min = 1 f XTAL *DC min DC = duty cycle
For two consecutive TCLs the deviation caused by the duty cycle of fXTAL is compensated so the duration of 2TCL is always 1/fXTAL. The minimum value TCLmin therefore has to be used only once for timings that require an odd number of TCLs (1,3,...). Timings that require an even number of TCLs (2,4,...) may use the formula: 2TCL = 1 f XTAL
Note
The address float timings in Multiplexed bus mode (t11 and t45) use the maximum duration of TCL (TCLmax = 1/fXTAL * DCmax) instead of TCLmin.
If bit OWDDIS in the SYSCON register is cleared, the PLL runs on its free-running frequency and delivers the clock signal for the Oscillator Watchdog. If bit OWDDIS is set, then the PLL is switched off.
16.4.6 Oscillator Watchdog (OWD)
When the clock option selected is direct drive or direct drive with prescaler, in order to provide a fail safe mechanism in case of a loss of the external clock, an oscillator watchdog is implemented as an additional functionality of the PLL circuitry. This oscillator watchdog operates as follows: After a reset, the Oscillator Watchdog is enabled by default. To disable the OWD, the bit OWDDIS (bit 4 of SYSCON register) must be set. When the OWD is enabled, the PLL is running on its free-running frequency, and increment the Oscillator Watchdog counter. On each transition of XTAL1 pin, the Oscillator Watchdog is cleared. If an external clock failure occurs, then the Oscillator Watchdog counter overflows (after 16 PLL clock cycles). The CPU clock signal will be switched to the PLL free-running clock signal, and the Oscillator Watchdog Interrupt Request (XP3INT) is flagged. The CPU
48/75

ST10F163 Data Sheet
16-Electrical Characteristics
clock will not switch back to the external clock even if a valid external clock exits on XTAL1 pin. Only a hardware reset can switch the CPU clock source back to direct clock input. When the OWD is disabled, the CPU clock is always fed from the oscillator input and the PLL is switched off to decrease power supply current.
16.4.7 Phase locked loop
For all other combinations of pins P0.15-13 (P0H.7-5) during reset the on-chip phase locked loop is enabled and provides the CPU clock (see table above). The PLL multiplies the input frequency by the factor F which is selected via the combination of pins P0.15-13 (i.e. fCPU = fXTAL * F). With every F'th transition of fXTAL the PLL circuit synchronizes the CPU clock to the input clock. This synchronization is done smoothly, i.e. the CPU clock frequency does not change abruptly. Due to this adaptation to the input clock the frequency of fCPU is constantly adjusted so it is locked to fXTAL. The slight variation causes a jitter of fCPU which also effects the duration of individual TCLs. The timings listed in the AC Characteristics that refer to TCLs therefore must be calculated using the minimum TCL that is possible under the respective circumstances. The actual minimum value for TCL depends on the jitter of the PLL. As the PLL is constantly adjusting its output frequency so it corresponds to the applied input frequency (crystal or oscillator) the relative deviation for periods of more than one TCL is lower than for one single TCL (see formula and figure below). For a period of N * TCL the minimum value is computed using the corresponding deviation D N: TCL min = TCL NOM * ( 1 - lD N l 100 ) D N = ( 4 - N 15 ) [ % ] where N = number of consecutive TCLs and 1 N 40. So for a period of 3 TCLs (N = 3): D 3 = 4 - 3 15 = 3.8% 3TCL min = 3TCL NOM x ( 1 - 3.8 100 ) = TCL NOM x 0.962 ( 57.72nsec@f CPU = 25MHz ) This is especially important for bus cycles using waitstates and e.g. for the operation of timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train

Figure 22 CLKOUT and READY 1 2 3 4 5 Cycle as programmed, including MCTC waitstates (Example shows 0 MCTC WS). The leading edge of the respective command depends on RW-delay. READY sampled HIGH at this sampling point generates a READY controlled waitstate, READY sampled LOW at this sampling point terminates the currently running bus cycle. READY may be deactivated in response to the trailing (rising) edge of the corresponding command (RD or WR). If the Asynchronous READY signal does not fulfill the indicated setup and hold times with respect to CLKOUT (e.g. because CLKOUT is not enabled), it must fulfill t 37 in order to be safely synchronized. This is guaranteed, if READY is removed in response to the command (see Note 4)). Multiplexed bus modes have a MUX waitstate added after a bus cycle, and an additional MTTC waitstate may be inserted here. For a multiplexed bus with MTTC waitstate this delay is 2 CLKOUT cycles, for a demultiplexed bus without MTTC waitstate this delay is zero. The next external bus cycle may start here.

Even if BREQ is activated earlier, the regain-sequence is initiated by HOLD going high. Please note that HOLD may also be deactivated without the ST10F163 requesting the bus. The next ST10F163 driven bus cycle may start here.

Figure 26 SSP read timing 1 2 3 The transition of shift and latch edge of SSPCLK is programmable. This figure uses the falling edge as shift edge (drawn bold). The bit timing is repeated for all bits to be transmitted or received. The active level of the chip enable lines is programmable. This figure uses an active low CE (drawn bold). At the end of a transmission or reception the CE signal is disabled in single transfer mode. In continuous transfer mode it remains active.
