Word width Word width for SC73P2602 is 9-bit, that is 2K word is 2K×9-bit. 2. Instruction period Instruction and internal operation are both based on main clock. The instruction period is the time of executing a whole instruction. There are single-/double-period instructions available for SC73P2602. An instruction period consists of 5 beat which is a system clock period (1/FMAIN). Hence, an instruction period is 5/ FMAIN. 3. PC PC for SC73P2602 is 11-bit and the maximum addressable memory is 2K. PC value is the address of next instruction to be executed and it is 0 after reset. In general, PC is added by 1 after executing an instruction because instructions for SC73P2602 is single-byte instruction. Fixed value is evaluated to PC when executing jump, subprogram call and subprogram return. 4. MBR Memory buffer register (MBR) is the write-only, higher 5-bit of the program pointer. The ROM of SC73P1602 can be divided into 15 blocks and each block has 128 bytes. These blocks can be addressed by the MBR. For program jump, the BLOCK value containing the target address should be loaded to MBR before executing BSS addr7 instruction. 5. STACK 11-bit stack register is used for storing PC when calling subprogram. 3-level subprogram can be called for there is only 3-level hardware stack registers in SC73P2602. 6. B, H, D 4-bit data look-up pointer registers. Lower 3-bit of register B and all bits (4-bit) of H, D are used as pointers pointing to data table when accessing constant data in OTP whose space of 2K can be used for data table or program memory, otherwise, register B, H, D act as general purpose register as others. Constant data stored in the table can be accessed through table look-up instruction. 7. ALU The arithmetic and logic unit plays a leading role in performing various operations of 4-bit binaries. The operation of ALU will change the carry flag (CF) and the zero flag (ZF). 8. ACC 4-bit accumulator, it is mostly used to store data and results.

SF is 1 after reset. 11. CH0, CH1, CL0, CL1 CH0, CH1, CL0 and CL1 are carrier level control registers for controlling the high and low level to (CH+1)/Fosc and(CL+1)/Fosc. Where, Fosc is oscillator frequency, CH0 and CH1 are higher 4-bit and lower 4-bit of CH respectively, while CL0 and CL1 are higher 4-bit and lower 4-bit of CL. 12. LL, LH 4-bit LL register, lower 4-bit of RAM addressing pointer, can be used as general register as well. 4-bit LH register, LH[0] is the MSB of RAM addressing pointer. Note: LH[3] is LVD flag and it is “0” when VDD< VLVD, otherwise it is “1”. Typical application: this bit is used for judging whether the circuit is working in low-voltage area to avoid incomplete code transmission. Typical value for is VLVD 1.7V. 13. PR (PR, PR2) The port mode register, which specifies the input mode or output mode of the I/O port, is 4-bit write-only. When PR=1, the corresponding port is set to output mode. PR=0, it is set to input mode. The execution of the HOLD instruction won’t affect the I/O modes of operation. When reset, PR=0. The port is in input mode.

Write TM: 17-bit timer run enable, P53 structure select and carrier generator enable; Read TM: the 12th~15th bit value of 17-bit timer (the lowest bit is the first bit) 15. OTP address assignment OTP ROM for SC73P2602 is 2K (9-bit), and the address assignment is shown below: Address 0000H ~ 003FH 0040H ~ 07FFH 16. RAM Data memory consists of 32x4 bits and is used to store temporary data and results after a program is executed. It can address the entire RAM areas by r LH[0] and LL[3:0]. When reset, the contents of RAM are not defined. It is recommend to initialize it at the beginning of program. 17. TIMER SC73P2602 has one 17-bit timer whose operating frequency is FC＝FMAIN. Description Subprogram entry address (can be multiplexed as normal program area ) Program area (can be multiplexed as data table) HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: //www.silan.com.cn REV:1.1 2009.11.19 Page 10 of 28 Reset value for timer is 1FFFFH, and it counts down. th WDT overflow reset signal is generated if the 17 bit of timer is converted from “1” to “0”. Timer is reset if system is reset (including power-up reset, low-voltage reset and WDT overflow reset), HOLD is cleared or reset instruction TMRST is executed. th Program is only executed when the 12 bit of time is converted from “1” to “0” after HOLD cleared. 18. Carrier generator Various carrier with different duty factors and frequencies are generated through setting high/low level duration by carrier register (see CH0, CH1, CL0, CL1 description). 19. I/O port SC73P2602 has 5 groups (20 in all) of I/O ports and most have both input/output modes (except P00 and P01 can only be used as input and P53 can only be used as output), details are as follows: P00-P01: input pin with pull-up resistor. It can be used for keyboard scan input and input low level can clear HOLD status; P02-P03: input/output port. The input/output characteristic is decided by PR. When used as input port, it has pullup resistor and can be used as keyboard scan input, input low level can clear HOLD status; when used as output pin, it can be used for keyboard scan output and output low level can drive LED directly. P10-P13: same as P02; P20-P23: same as P02; P30-P33: same as P02; P50-P52: same as P02; P53: output infrared remote signal with carrier. There are two structures: push-pull structure is for external infrared emitter driving and big current open-drain structure is for driving infrared emitter directly, with opposite pole of the former structure.
