Contention between Overflow and Counter Clearing: If overflow and counter clearing occur
simultaneously, the TCFV flag in TSR is not set and TCNT clearing takes precedence.
Figure 8.47 shows the operation timing when a TGR compare-match is specified as the clearing
source, and H'FFFF is set in TGR.

Contention between TCNT Write and Overflow: If there is an up-count in the T2 state of a
TCNT write cycle, and overflow occurs, the TCNT write takes precedence and the TCFV flag in
TSR is not set .
Figure 8.48 shows the operation timing in this case.
