TC9028P Overview
of the hardware configuration and operation of the ponents listed above. Internal CPU functions 2.1 Program counter (PC) The program counter is a 10 bit binary counter which holds the program memory address of the next instruction to be executed. The program counter is normally incremented for each instruction fetch.
