11.2.3
The compare match timer counter (CMCNT) is a 16-bit register used as an upcounter for
generating interrupt requests.
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 that clock. When the CMCNT
value matches that of the compare match timer constant register (CMCOR), the CMCNT is
cleared to H'0000 and the CMF flag of the CMCSR is set to 1. If the CMIE bit of the CMCSR is
set to 1 at this time, a compare match interrupt (CMI) is requested.
The CMCNT is initialized to H'0000 by power-on resets.

Bits 1, 0—Clock Select 1, 0 (CKS1, CKS0): These bits select the clock input to the CMCNT
from among the four internal clocks obtained by dividing the system clock ( ). When the STR
bit of the CMSTR is set to 1, the CMCNT begins incrementing with the clock selected by
CKS1 and CKS0.
