23.6.6 Contention between TGR Write Operation and Compare Match
If a compare match occurs in a TGR write cycle, the TGR register write operation is executed and the compare match
signal is also generated.
Figure 23.99 shows the timing in this case.

23.6.7 Contention between Buffer Register Write Operation and Compare Match
If a compare match occurs in a TGR write cycle, the data before write operation is transferred to the TGR register by the
buffer operation.
Figure 23.100 shows the timing in this case.
