Notes: 1. Includes switching from low to stop, and from stop to low.

2. Includes switching from stop to high.

3. Includes switching from high to stop.

4. Generated on the assumption that the switchover is a falling edge; TCNT is

incremented.

13.6.6 Interrupts and Module Stop Mode

If module stop mode is entered when an interrupt has been requested, it will not be possible to

clear the CPU interrupt source or DMAC and DTC activation source. Interrupts should therefore

be disabled before entering module stop mode.
