PRODUCT OVERVIEW
FUNCTION OVERVIEW
SAM47 CPU All KS57-series microcontrollers have the advanced SAM47 CPU core. The SAM47 CPU can directly address up to 32 K bytes of program memory. The arithmetic logic unit (ALU) performs 4-bit addition, subtraction, logical, and shift-and-rotate operations in one instruction cycle and most 8-bit arithmetic and logical operations in two cycles. CPU REGISTERS Program Counter A 11-bit program counter (PC) stores addresses for instruction fetch during program execution. Usually, the PC is incremented by the number of bytes of the instruction being fetched. An exception is the 1-byte instruction REF which is used to reference instructions stored in a look-up table in the ROM. Whenever a reset operation or an interrupt occurs, bits PC11 through PC0 are set to the vector address. Bit PC13-12 is reserved to support future expansion of the device's ROM size. Stack Pointer An 8-bit stack pointer (SP) stores addresses for stack operations. The stack area is located in the general-purpose data memory bank 0. The SP is read or written by 8-bit instructions and SP bit 0 must always be set to logic zero. During an interrupt or a subroutine call, the PC value and the program status word (PSW) are saved to the stack area in RAM. When the service routine has completed, the values referenced by the stack pointer are restored. Then, the next instruction is executed. The stack pointer can access the stack regardless of data memory access enable flag status. Since the reset value of the stack pointer is not defined in firmware, it is recommended that the stack pointer be initialized to 00H by program code. This sets the first register of the stack area to data memory location 0FFH. PROGRAM MEMORY In its standard configuration, the 4096 x 8-bit ROM is divided into three functional areas: -- 16-byte area for vector addresses -- 96-byte instruction reference area -- 1920-byte general purpose area (KS57C01502) -- 3968-byte general purpose area (KS57C01504) The vector address area is used mostly during reset operations and interrupts. These 16 bytes can also be used as general-purpose ROM. The REF instruction references 2 x 1-byte and 2-byte instructions stored in locations 0020H-007FH. The REF instruction can also reference 3-byte instructions such as JP or CALL. In order for REF to be able to reference these instructions, however, JP or CALL must be shortened to a 2-byte format. To do this, JP or CALL is written to the reference area with the format TJP or TCALL instead of the normal instruction name. Unused locations in the instruction reference area can be allocated to general-purpose use.

DATA MEMORY Overview Data memory is organized into three areas: -- 32 x 4-bit working registers -- 224 x 4-bit general-purpose area in bank 0 -- 256 x 4-bit general-purpose area in bank 1 -- 128 x 4-bit area in bank 15 for memory-mapped I/O addresses Data stored in data memory can be manipulated by 1-, 4-, and 8-bit instructions. Data memory is organized into two memory banks -- bank 0, bank 1 and bank 15. The select memory bank instruction (SMB) selects the bank to be used as working data memory. After power-on reset operation, initialization values for data memory must be redefined by code. Data Memory Addressing Modes The enable memory bank (EMB) flag controls the addressing mode for data memory banks 0, 1 or 15. When the EMB flag is logic zero, restricted area can be accessed. When the EMB flag is set to logic one, all two data memory banks can be accessed according to the current SMB value. The EMB = "0" addressing mode is used for normal program execution, whereas the EMB = "1" mode is commonly used for interrupts, subroutines, mapped I/O, and repetitive access of specific RAM addresses. Working Registers The RAM's working register area in data memory bank 0 is further divided into four register banks. Each register bank has eight 4-bit registers that are addressable either by 1-bit or 4-bit instructions. Paired 4-bit registers can be addressed as double registers by 8-bit instructions. Register A is the 4-bit accumulator and double register EA is the 8-bit extended accumulator. Double registers WX, WL, and HL are used as data pointers for indirect addressing. Unused working registers can be used as general-purpose memory. To limit the possibility of data corruption due to incorrect register bank addressing, register bank 0 is usually used for the main program and banks 1, 2, and 3 for interrupt service routines.

PRODUCT OVERVIEW
CONTROL REGISTERS Program Status Word The 8-bit program status word (PSW) controls ALU operations and instruction execution sequencing. It is also used to restore a program's execution environment when an interrupt has been serviced. Program instructions can always address the PSW regardless of the current value of data memory enable flags. Before an interrupt or subroutine is processed, the PSW values are pushed onto the stack in data memory bank 0. When the service routine is completed, the PSW values are restored. IS1 C IS0 SC2 EMB SC1 ERB SC0
Interrupt status flags (IS1, IS0), the enable memory bank and enable register bank flags (EMB, ERB), and the carry flag (C) are 1- and 4-bit read/write or 8-bit read-only addressable. You can address the skip condition flags (SC0-SC2) using 8-bit read instructions only. Select Bank (SB) Register Two 4-bit registers store address values used to access specific memory and register banks: the select memory bank register, SMB, and the select register bank register, SRB. 'SMB n' instruction selects a data memory bank (0 or 15) and stores the upper four bits of the 12-bit data memory address in the SMB register. To select register bank 0, 1, 2, or 3, and store the address data in the SRB, you can use the instruction 'SRB n'. The instructions "PUSH SB" and "POP SB" move SRB and SMB values to and from the stack for interrupts and subroutines. CLOCK CIRCUITS System oscillation circuit generates the internal clock signals for the CPU and peripheral hardware. The system clock can use a crystal, or ceramic oscillation source, or an externally-generated clock signal. To drive KS57C01502/C01504 using an external clock source, the external clock signal should be input to Xin, and its inverted signal to Xout. 4-bit power control register controls the oscillation on/off, and select the CPU clock. The internal system clock signal (fx) can be divided internally to produce three CPU clock frequencies -- fx/4, fx/8, or fx/64. INTERRUPTS Interrupt requests may be generated internally by on-chip processes (INTB, INTT0, and INTS) or externally by peripheral devices (INT0 and INT1). There are two quasi-interrupts: INTK and INTW. INTK (KS0-KS2) detects falling edges of incoming signals and INTW detects time intervals of 0.5 seconds or 3.91 milliseconds. The following components support interrupt processing: -- Interrupt enable flags -- Interrupt request flags -- Interrupt priority registers -- Power-down termination circuit

PRODUCT OVERVIEW
KS57C01502/C01504/P01504
POWER-DOWN To reduce power consumption, there are two power-down modes: idle and stop. The IDLE instruction initiates idle mode; the STOP instruction initiates stop mode. In idle mode, the CPU clock stops while peripherals continue to operate normally. In stop mode, system clock oscillation stops completely, halts all operations except for a few basic peripheral functions. A power-down is terminated either by a or by an interrupt (with exception of the external interrupt INT0).
RESET
When is input during normal operation or during power-down mode, a reset operation is initiated and the CPU enters idle mode. When the standard oscillation stabilization time interval (31.3 ms at 4.19 MHz) has elapsed, normal CPU operation resumes. I/O PORTS The KS57C01502/C01504 has seven I/O ports. Pin addresses for all I/O ports are mapped to locations FF0H- FF6H in bank 15 of the RAM. There are 6 input pins and 18 configurable I/O pins including 8 high current I/O pins for a total of 24 I/O pins. The contents of I/O port pin latches can be read, written, or tested at the corresponding address using bit manipulation instructions. TIMERS and TIMER/COUNTER The timer function has three main components: an 8-bit basic timer, an 8-bit timer/counter, and a watch timer. The 8-bit basic timer generates interrupt requests at precise intervals, based on the selected internal clock frequency. The programmable 8-bit timer/counter is used for counting events, modifying internal clock frequencies, and dividing external clock signals. The 8-bit timer/counter generates a clock signal ( ) for the serial I/O interface. The watch timer consists of an 8-bit watch timer mode register, a clock selector, and a frequency divider circuit. Its functions include real-time, watch-time measurement, and clock generation for frequency output for buzzer sound. SERIAL I/O INTERFACE The serial I/O interface supports the transmission or reception of 8-bit serial data with an external device. The serial interface has the following functional components: -- 8-bit mode register -- Clock selector circuit -- 8-bit buffer register -- 3-bit serial clock counter The serial I/O circuit can be set to transmit-and-receive, or to receive-only mode. MSB-first or LSB-first transmission is also selectable. The serial interface can operate with an internal or an external clock source, or using the clock signal generated by the 8-bit timer/counter. Transmission frequency can be modified by setting the appropriate bits in the SIO mode register.

PRODUCT OVERVIEW
BIT SEQUENTIAL CARRIER The bit sequential carrier (BSC) is a 16-bit register that can be manipulated using 1-, 4-, and 8-bit instructions. Using 1-bit indirect addressing, addresses and bit locations can be specified sequentially. In this way, programs can process 16-bit data by moving the bit location sequentially and then incrementing or decrementing the value of the L register. BSC data can also be manipulated using direct addressing. COMPARATOR The KS57C01502/C01504 contains a 4-channel comparator which can be multiplexed to normal input port. -- Conversion time: 15.2 s, 121.6 s at 4.19 MHz -- Two operation modes: Three channels for analog input and one channel for external reference voltage input Four channels for analog input and internal reference voltage level -- 16-level internal reference voltage generator -- 150 mV accuracy for input voltage level difference detection (maximum) -- Comparator enable and disable The comparison results are read from the 4-bit CMPREG register after the specified conversion time.

OVERVIEW
KS57P01504 OTP
The KS57P01504 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the KS57C01502/C01504 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data format. The KS57P01504 is fully compatible with the KS57C01502/C0504, both in function and in pin configuration. Because of its simple programming requirements, the KS57P01504 is ideal for use as an evaluation chip for the KS57C01502/C01504.
