CMCR sets the clock used for counting up.
CKS[1:0] Bits (Clock Select)
These bits select the clock to be input to CMCNT from four internal clocks obtained by dividing the peripheral clock
(PCLK).
When the STRj (j = 0 to 3) bit in CMSTRy (y = 0 or 1) is set to 1, CMCNT starts counting up on the clock selected with
bits CKS[1:0].
CMIE Bit (Compare Match Interrupt Enable)
The CMIE bit enables or disables compare match interrupt (CMIm) (m = 0 to 3) generation when CMCNT and CMCOR
values match.
