Contention between TGR Write and Compare Match:
If a compare match occurs in the T2 state of a TGR write cycle, the TGR write takes priority and
the compare match signal is disabled. A compare match does not occur even if the same value as
before is written to. Figure 12.49 shows the timing in this case.
