Section 20 Compare Match Timer (CMT)
20.5
20.5.1
The CMT operation can be disabled or enabled using the standby control register. The initial
setting is for CMT operation to be halted. Access to a register is enabled by clearing module
standby mode. For details, refer to section 26, Power-Down Modes.
20.5.2
When the compare match signal is generated in the T2 cycle while writing to CMCNT, clearing
CMCNT has priority over writing to it. In this case, CMCNT is not written to. Figure 20.5 shows
the timing to clear the CMCNT counter.
