Note:
Instruction execution cycles: The execution cycles shown in the table are minimums. The
actual number of cycles may be increased:
1. When contention occurs between instruction fetches and data access, or
2. When the destination register of the load instruction (memory â register) and the
register used by the next instruction are the same.
