12.6.3
During the T2 state of a TCOR write cycle, the TCOR write has priority even if a compare-match
occurs and the compare-match signal is disabled. Figure 12.15 shows this operation.
With TMRX, an ICR input capture contends with a compare-match in the same way as with a
write to TCORC. In this case, the input capture has priority and the compare-match signal is
inhibited.
