Control Registers
(1) Program counter (PC)
This is a 16-bit register that holds an address of the instruction to be executed next.
(2) Program status word (PSW)
This 16-bit register indicates the status of the CPU as a result of instruction execution.
(3) Stack pointer (SP)
This 16-bit register indicates the first address of the stack area (LIFO) of the memory.
(4) CPU control word (CCW)
This 8-bit register is used to control the CPU.
