Section 12 Compare Match Timer (CMT)
12.5.3
Even when the count-up occurs in the T2 cycle while writing to CMCNT in bytes, the writing has
priority over the count-up. In this case, the count-up is not performed. The byte data on the other
side, which is not written to, is also not counted and the previous contents are retained.
Figure 12.7 shows the timing when the count-up occurs in the T2 cycle while writing to
CMCNTH in bytes.
12.5.4
Do not set the same value in CMCNT and CMCOR while CMCNT is not counting.
