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.
10.6.6 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 the DTC activation source. Interrupts should therefore be
disabled before entering module stop mode.
