User's program and fixed data are stored in the program ROM. User's program is executed using the PC value to fetch an instructioncode. The 32Kx8 bits program ROM can be divided into 8 banks. There are 4Kx8 bits per bank. The program ROM bank is selected by P3(2..0). The program counter is a 13-bit binary counter. The PC and P3 are initialized to "0" during reset. When P3(2..0)=000B, the bank0 and bank1 of program ROM will be selected. P3(2..0)=001B, the bank0 and bank2 will be selected, and so on.

Fixed data can be read out by table-look-up instruction. Table-look-up instruction requires the Data point (DP) to indicate the ROM address in obtaining the ROM code data (Except bank0) : LDAX LDAXI Acc ROM[DP]L Acc ROM[DP]H,DP+1
DP is a 12-bit data register that stores the program ROM address as pointer for the ROM code data. User has to initially load ROM address into DP with instructions "STADPL", and "STADPM", "STADPH", then to obtain the lower nibble of ROM code data by instruction "LDAX" and higher nibble data by instruction "LDAXI". PROGRAM EXAMPLE: Read out the ROM code of address 1777h by table-look-up instruction.

STACK: There are 13 - level (maximum) stack levels that user can use for subroutine (including interrupt and CALL). User can assign any level be the starting stack by providing the level number to stack pointer (SP) . When an instruction (CALL or interrupt) is invoked, before enter the subroutine, the previous PC address is saved into the stack until returned from those subroutines, the PC value is restored by the data saved in stack. DATA AREA: Except the area used by user's application, the whole RAM can be used as data area for storing and loading general data. ADDRESSING MODE The 500 nibble data memory consists of two banks (bank 0 and bank 1). There are 244x4 bits (address 000h~0F3h) in bank 0 and 256x4 bits (address 100h~1FFh) in bank 1. * This specification are subject to be changed without notice.

ACCUMULATOR Accumulator(ACC) is a 4-bit data register for temporary data storage. For the arithematic, logic and comparative opertion.., ACC plays a role which holds the source data and result . FLAGS There are three kinds of flag, CF ( Carry flag ), ZF ( Zero flag ) and SF ( Status flag ), these three 1-bit flags are included by the arithematic, logic and comparative .... operation . All flags will be put into stack when an interrupt subroutine is served, and the flags will be restored after RTI instruction is executed . (1) Carry Flag ( CF ) The carry flag is affected by the following operations: a. Addition : CF as a carry out indicator, under addition operation, when a carry-out occures, the CF is "1", likewise, if the operation has no carry-out, the CF is "0". b. Subtraction : CF as a borrow-in indicator, under subtraction operation, when a borrow occures, the CF is "0", likewise, if there is no borrow-in, the CF is "1". c. Comparision: CF as a borrow-in indicator for Comparision operation as in the subtraction operation. d. Rotation: CF shifts into the empty bit of accumulator for the rotation and holds the shift out data after rotation. e. CF test instruction : Under TFCFC instruction, the CF content is sent into SF then clear itself as "0". Under TTSFC instruction, the CF content is sent into SF then set itself as "1". (2) Zero Flag ( ZF ) ZF is affected by the result of ALU, if the ALU operation generates a "0" result, the ZF is "1", likewise, the ZF is "0". (3) Status Flag ( SF ) The SF is affected by instruction operation and system status . a. SF is initiated to "1" for reset condition . b. Branch instruction is decided by SF, when SF=1, branch condition is satisified, likewise, when SF = 0, branch condition is unsatisified . PROGRAM EXAMPLE: Check following arithematic operation for CF, ZF, SF

ALU FUNCTION (1) Addition: ALU supports addition function with instructions ADDAM, ADCAM, ADDM #k, ADD #k,y .... . The addition operation affects CF and ZF. Under addition operation, if the result is "0", ZF will be "1", otherwise, ZF will be "0", When the addition operation has a carry-out. CF will be "1", otherwise, CF will be "0". EXAMPLE:
Operation 3+4=7 7+F=6 0+0=0 8+8=0 Carry 0 1 0 1 Zero 0 0 1 1
(2) Subtraction: ALU supports subtraction function with instructions SUBM #k, SUBA #k, SBCAM, DECM... . The subtraction operation affects CF and ZF, Under subtraction operation, if the result is negative, CF will be "0", and a borrow out, otherwise, if the result is positive, CF will be "1". For ZF, if the result of subtraction operation is "0", the ZF is "1", likewise, ZF is "1". EXAMPLE:
Operation 8-4=4 7-F= -8(1000) 9-9=0 Carry 1 0 1 Zero 0 0 1 8.11.2000 11

STACK POINTER (SP) Stack pointer is a 4-bit register that stores the present stack level number. Before using stack, user must set the SP value first, CPU will not initiate the SP value after reset condition . When a new subroutine is received, the SP is decreased by one automatically, likewise, if returning from a subroutine, the SP is increased by one . The data transfer between ACC and SP is done with instructions "LDASP" and "STASP". DATA POINTER (DP) Data pointer is a 12-bit register that stores the ROM address can indicating the ROM code data specified by user (refer to data ROM).
CLOCK AND TIMING GENERATOR The clock generator is supported by a dual clock system. The high-frequency oscillator is sourced from RC oscillator, the working frequency range is 480 KHz to 4 MHz defined by the mask option. The low-frequency oscillator may be sourced from crystal or RC oscillator as defined by mask option, the working frequency is 32 KHz.

TIMER / COUNTER ( TIMERA, TIMERB) Timer/counters support three special functions: 1. Even counter 2. Timer. 3. Pulse-width measurement. These three functions can be executed by 2 timer/counter independently. With timerA, the counter data is saved in timer register TAH, TAM, TAL. User can set counter initial value and read the counter value by instruction "LDATAH(M,L)" and "STATAH(M,L)". With timer B register is TBH, TBM, TBL and the W/R instruction are "LDATBH (M,L)" and "STATBH (M,L)". The basic structure of timer/counter is composed by two identical counter module , these two modules can be set initial timer or counter value to the timer registers, P28 and P29 are the command registers for timerA and timer B, user can choose different operation modes and internal clock rates by setting these two registers. When timer/counter overflows, it will generate a TRGA(B) interrupt request to interrupt control unit.

TIMER/COUNTER FUNCTION
ary relimin P
Timer/counterA,B are programmable for timer, event counter and pulse width measurement mode. Each timer/counter can execute any of these functions independently. EVENT COUNTER MODE under event counter mode, the timer/counter is increased by one at any rising edge of P8.1/TRGB for timerB (P8.3/TRGA for timer A). When timerB (timerA) counts overflow, it will provide an interrupt request TRGB (TRGA) to interrupt control unit.

User can choose up to 4 types of internal pulse rate by setting IPSB for timerB (IPSA for timerA). When timer/counter counts overflow, An interrupt request will be sent to interrupt control unit.

The preset value of timer/counter register is calculated as following procedure. Internal pulse rate: LXIN/23 ; LXIN = 32KHz The time of timer counter count one = 23 /LXIN = 8/32768=0.244ms The number of internal pulse to get timer overflow = 60 ms/ 0.244ms = 245.901= 0F6h The preset value of timer/counter register = 1000h - 0F6h = F0Ah
