Section 2 CPU
Notes: 1. The normal minimum number of execution cycles is two, but five cycles are required
when the operation result is read from the MAC register immediately after the
instruction.
2. The normal minimum number of execution cycles is one, but three cycles are required
when the operation result is read from the MAC register immediately after the MUL
instruction.

Note: * An on-chip DMAC bus cycle is not inserted between a TAS instruction operand read
cycle and write cycle. Also, bus release is not performed by BREQ.
