Contention between TGR Write and Compare Match: If a compare match occurs in the T
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 9.47
shows the timing in this case.
