FUNCTION DESCRIPTION
SC73P1601 includes 4-bit MCU, outlay oscillator, system reset module. Next we will mainly introduce the
functions.
1. PC
PC refers to the program address pointer, 10 bits. The maximum addressing space is 1K ROM .The program
counter contains the address of the instruction that will be executed next. The PC value is cleared to 0 after reset.
The PC is set to predefined value when one of the 3 following occasions occurs: 1) when the JUMP instruction is
executed; 2) when a subroutine call is back; 3) when a program call is back. In the SC73P1601, all instructions
are one-byte instructions, PC increments by 1 each time an instruction is executed.
