20.2.3
CMCNT is a 16-bit register used as an up-counter. When the counter input clock is selected with
bits CKS1 and CKS0 in CMCSR and the STR bit in CMSTR is set to 1, CMCNT starts counting
using the selected clock.
When the value in CMCNT and the value in compare match constant register (CMCOR) match,
CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1.
The initial value of CMCNT is H'0000.
Initial value:
20.2.4
CMCOR is a 16-bit register that sets the interval up to a compare match with CMCNT.
The initial value of CMCOR is H'FFFF.
