10.7.17 Contention between TCNT Write and Overflow/Underflow
If there is an up-count or down-count in the T2 state of a TCNT write cycle, and
overflow/underflow occurs, the TCNT write takes precedence and the TCFV/TCFU flag in TSR is
not set.
Figure 10.84 shows the operation timing when there is contention between TCNT write and
overflow.
