Section 14 8-Bit Timers (TMR)
Notes: 1. Includes switching from low to stop, and from stop to low.
14.7.6
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.
14.7.7
TMR Operation 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 the module
stop state. For details, refer to section 26, Power-Down Modes.
14.7.8
If a transition is made to the module stop state 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 the module stop state.
