—: No change
Notes: 1. Instruction execution cycles: The execution cycles shown in the table are minimums.
The actual number of cycles may be increased when (1) contention occurs between
instruction fetches and data access, or (2) when the destination register of the load
instruction (memory → register) and the register used by the next instruction are the
same.
2. Depending on the instruction’s operand size, scaling is ×1, ×2, or ×4. For details, see
the SH-1/SH-2/SH-DSP Programming Manual.
