Section 12 8-Bit Timers
12.5.2
The CMFA and CMFB flags in TCSR are set to 1 by a compare-match signal generated when the
TCOR and TCNT values match. The compare-match signal is generated at the last state in which
the match is true, just before the timer counter is updated. Therefore, when TCOR and TCNT
match, the compare-match signal is not generated until the next incrementation clock input. Figure
12.5 shows the timing of CMF flag setting.
