(2) Contention between TCNT Write and Increment: If a timer counter increment pulse is
generated during the T
timer counter is not incremented.
Figure 8-14 shows this type of contention.
(3) Contention between TCOR Write and Compare-Match: If a compare-match occurs during
the T
match signal is inhibited.
Figure 8-15 shows this type of contention.
