Contention between TGR Write and Compare Match: If a compare match occurs in the T
2
state of a TGR write cycle, the TGR write takes precedence and the compare match signal is
inhibited. A compare match does not occur even if the same value as before is written. Figure
10.47 shows the timing in this case.
