13.3.2
One of four clocks (P /4, P /8, P /16, P /64) obtained by dividing the peripheral clock (P ) can
be selected by the CKS1 and CKS0 bits in CMCSR. Figure 13.3 shows the timing.
13.3.3
The CMF bit in CMCSR is set to 1 by the compare match signal generated when CMCOR and
CMCNT match. The compare match signal is generated upon the final state of the match (timing
at which the CMCNT matching count value is updated to H'0000). Consequently, after CMCOR
and CMCNT match, a compare match signal will not be generated until a CMCNT clock is input.
Figure 13.4 shows the CMF bit set timing.
