13.5.2
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 13.5 shows this timing.
