10.10.3 Conflict

between

TCOR Write and Compare-Match

If a compare-match occurs during the T

2

state of a TCOR write cycle as shown in figure 10.16, the

TCOR write takes priority and the compare-match signal is disabled. With TMR_X, and TMR_A,
a TICR input capture conflicts with a compare-match in the same way as with a write to TCORC.
In this case also, the input capture takes priority and the compare-match signal is disabled.
