Section 9 Timers
Compare Match Flag set Timing: Compare match flag A or B (CMFA or CMFB) is set to 1
when TCNTV matches TCORA or TCORB. The internal compare-match signal is generated in the
last state in which the values match (when TCNTV changes from the matching value to a new
value). Accordingly, when TCNTV matches TCORA or TCORB, the compare match signal is not
generated until the next clock input to TCNTV. Figure 9.7 shows the timing.

TMOV Output Timing: The TMOV output responds to compare match A or B by remaining
unchanged, changing to 0, changing to 1, or toggling, as selected by bits OS3 to OS0 in TCSRV.
Figure 9.8 shows the timing when the output is toggled by compare match A.
