Mitsubishi Microcomputers
then services any other enabled interrupts that occurred, in the order of their respective priorities, and
returns to its state prior to the execution of the STP instruction. The timing for the STP instruction is
shown in Figure 2-120.
2.16.2 Wait Mode
Use of the wait mode allows the microcomputer to be placed in a state where excitation of the CPU
is stopped, but the clocks to the peripherals continue to oscillate. This mode provides lower power
dissipation during the idle periods and quick wake-up time. The microcomputer enters the wait mode
when the WIT instruction is executed. After the instruction execution, P2 is held high and P1 is held
low.
Returning from wait mode is accomplished just as it is when returning from stop mode, with the
exception that you need not provide time for the oscillator to stabilize, because the oscillation never
stopped. Because P1PER and P2PER continue to oscillate in the wait mode, any peripheral interrupt
can be used to bring the microcomputer out of the wait mode. The timing for the WIT instruction is
shown in Figure 2-121.
