ITPEC FE Morning April 2021 — Question 11 of 80
Program Counter (PC) — a special register that holds the address of the next instruction to be fetched.
- •Accumulator — stores the result of arithmetic/logic operations
- •Program Counter (PC) — holds the address of the next instruction to fetch ✔
- •Stack Pointer — points to the top of the current stack in memory
- •Timer — hardware component for time tracking and interrupts
Why not others:
- (a) Accumulator — used for ALU results, not instruction addressing
- (c) Stack Pointer — tracks stack position, not instruction sequence
- (d) Timer — unrelated to instruction fetch cycle
Key rule: PC is automatically incremented after each instruction fetch to point to the next one.
