12.4.5 Timer Overflow Flag (OVF) Set Timing
OVF is set to 1 when TCF overflows from H'FFFF to H'0000.
12.4.6 Compare Match Flag Set Timing
The compare match flag (CMFH or CMFL) is set to 1 when the TCF and OCRF values match.
The compare match signal is generated in the last state during which the values match (when TCF
is updated from the matching value to a new value). When TCF matches OCRF, the compare
match signal is not generated until the next counter clock.
