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 precedence
and the compare match signal is prohibited. A compare match does not occur even if the same
value as before is written.
Figure 9.47 shows the timing in this case.
