PROGRAM COUNTER
The program counter (PC) is a 10-bit binary counter separated into the high-byte 2 bits and the low-byte 8 bits. This
counter is responsible for pointing a location in order to fetch an instruction for kernel circuit. Normally, the program
counter is automatically incremented with each instruction during program execution.
Besides, it can be replaced with specific address by executing CALL or JMP instruction. When JMP or CALL
instruction is executed, the destination address will be inserted to bit 0 ~ bit 9.
