Section 11 8-Bit Timers
11.5.2
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
11.5 shows the timing of CMF flag setting.
11.5.3
When a compare-match occurs, the timer output changes as specified by the output select bits
(OS3 to OS0) in TCSR. Figure 11.6 shows the timing when the output is set to toggle at compare-
match A.
