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.
11.8.6 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.
11.8.7 Module Stop Mode Setting
Operation of the TMR can be disabled or enabled using the module stop control register. The
initial setting is for operation of the TMR to be halted. Register access is enabled by clearing
module stop mode. For details, refer to section 22, Power-Down Modes.
