9.9.5
If incrementing occurs in the T2 state of a TCNT write cycle, the TCNT write takes precedence
and TCNT is not incremented. Figure 9.48 shows the timing in this case.
9.9.6
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 9.49shows the timing in this case.
