14.10.5 Conflict 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 14.48 shows the timing in this case.
14.10.6 Conflict between TGR Write and Compare Match
If a compare match occurs in the T2 state of a TGR write cycle, the TGR write takes precedence
and the compare match signal is disabled. A compare match also does not occur when the same
value as before is written.
Figure 14.49 shows the timing in this case.
