Contention between TCNT Write and Increment Operations

If incrementing occurs in the T2 state of a TCNT write cycle, the TCNT write takes precedence and TCNT is not
incremented.
Figure 10.100 shows the timing in this case.

Contention between TGR Write and Compare Match

If a compare match occurs in the T2 state of a TGR write cycle, the TGR write is executed and the compare match signal
is also generated.
Figure 10.101 shows the timing in this case.
