10.10.11 Contention between Overflow/Underflow and Counter Clearing
In the H8S/2268 Group, if overflow/underflow and counter clearing occur simultaneously, the
TCFV/TCFU flag in TSR is not set and TCNT clearing takes precedence.
In the H8S/2264 Group, if overflow and counter clearing occur simultaneously, the TCFV flag in
TSR is not set and TCNT clearing takes precedence.
Figure 10.53 shows the operation timing when a TGR compare match is specified as the clearing
source, and when H'FFFF is set in TGR.
