Accordingly, when the timer count matches one of the time constants, the compare-match signal is
not generated until the next period of the clock source. Figure 8-5 shows the timing of the setting
of the compare-match flags.
(2) Timing of Compare-Match Flag (CMFA or CMFB) Clearing: The compare-match flag
CMFA or CMFB is cleared when the CPU writes a 0 in this bit.
(3) Output Timing: When a compare-match event occurs, the timer output (TMO0 or TMO1)
changes as specified by the output select bits (OS3 to OS0) in the TCSR. Depending on these bits,
the output can remain the same, change to 0, change to 1, or toggle. If compare-match A and B
occur simultaneously, the higher priority compare-match determines the output level. See item (4)
in section 8.6, Application Notes for details.
