Notes: 1. Includes switching from low to stop, and from stop to low.
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 DTC activation source.
Interrupts should therefore be disabled before entering module stop mode.
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
