12.5.2
The CMFA and CMFB flags in TCSR are set to 1 by a compare-match signal generated when the
TCNT and TCOR values match. The compare-match signal is generated at the last state in which
the match is true, just when the timer counter is updated. Therefore, when TCNT and TCOR
match, the compare-match signal is not generated until the next TCNT input clock. Figure 12.6
shows the timing of CMF flag setting.
12.5.3
When a compare-match signal occurs, the timer output changes as specified by the OS3 to OS0
bits in TCSR. Figure 12.7 shows the timing of timer output when the output is set to toggle by a
compare-match A signal.
