8.3.2 Compare Match Timing
(1) Setting of Compare-Match Flags A and B (CMFA and CMFB): The compare-match flags
are set to 1 by an internal compare-match signal generated when the timer count matches the time
constant in TCNT or TCOR. The compare-match signal is generated at the last state in which the
match is true, just before the timer counter increments to a new value.
