What is Program counter?

  Shared By: Adelita Fischer    Date: Nov 12    Category: Assembly Language    Views: 4101


Program counter holds the address of either the first byte of the next instruction to be fetched for execution or the address of the next byte of a multi byte instruction, which has not been completely fetched. In both the cases it gets incremented automatically one by one as the instruction bytes get fetched. Also Program register keeps the address of the next instruction.
