11.2.4
The compare match timer constant register (CMCOR) is a 16-bit register that sets the compare
match period with the CMCNT.
The CMCOR is initialized to H'FFFF by power-on resets.

11.3.1
When an internal clock is selected with the CKS1, CKS0 bits of the CMCSR register and the STR
bit of the CMSTR is set to 1, the CMCNT begins incrementing with the selected clock. When the
CMCNT counter value matches that of the compare match constant register (CMCOR), the
CMCNT counter is cleared to H'0000 and the CMF flag of the CMCSR register is set to 1. If the
CMIE bit of the CMCSR register is set to 1 at this time, a compare match interrupt (CMI) is
requested. The CMCNT counter begins counting up again from H'0000.
Figure 11.2 shows the compare match counter operation.
