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.
12.8.6 Mode Setting with Cascaded Connection
If 16-bit counter mode and compare match count mode are specified at the same time, input clocks
for TCNT_0 and TCNT_1 are not generated, and the counter stops. Do not specify 16-bit counter
and compare match count modes simultaneously.
12.8.7 Interrupts in 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 and DMAC activation source. Interrupts should
therefore be disabled before entering module stop mode.
