4BIT MICROCONTROLLER
hee1. Description
taSSD6830 is a remote control transmitter, consists of the optimized 4-bit CPU with ROM and
aRAM. It contains power-on reset, watchdog timer and carrier frequency generator. The
.DSD6830 provide a various carrier frequency for encoding output of key matrix and has
wbuilt-in transistor to drive infrared LED. The SD6830 is supported with a software
wwdevelopment tool, which allows code development in a PC environment. It allows the user
to simulate the SD6830 on an instruction level.

6.3 Data Memory (RAM)
Data memory is used to store various type of processing data. This consists of a 32-nibble,
which is organized into two files of 16 nibbles each. RAM addressing is indirectly
implemented by a two registers; H, L. It’s upper 1-bit register (H) selects one of two files
and its lower 4-bit register (L) selects one of 16 nibbles in the selected file.
REG H (1-bit)
REG L ( 4-bit )

6.4 Stack Register (SK)
Stack register is used to store return address and provide a particularly mechanism for
transferring control between programs. Two level hardware push/pop stacks are
manipulated by CAL, CALL, and RET instructions. CAL/CALL instructions push the current
program counter value, incremented by “1”, into stack level 1. Stack level 1 is
automatically pushed to level 2.
If more than two subsequent CAL/CALL are executed, only the most recent two return
addresses are stored. RET instruction load the contents of stack level 1 into the program
counter while stack level 2 gets copied into level 1. If more than two subsequent RET are
executed, the stack will be filled with the address previously stored in level 2.
