Contention between TGR Write and Compare Match: If a compare match occurs in the T
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 10-51 shows the timing in this case.
Contention between Buffer Register Write and Compare Match: If a compare match occurs in the T
write cycle, the data transferred to TGR by the buffer operation will be the data prior to the write.
Figure 10-52 shows the timing in this case.
