Section 12 16-Bit Timer Pulse Unit (TPU)
12.10.11 Contention between Overflow/Underflow and Counter Clearing
If overflow/underflow and counter clearing occur simultaneously, the TCFV/TCFU flag in TSR is
set and TCNT clearing is also performed.
Figure 12.53 shows the operation timing when a TGR compare match is specified as the clearing
source, and H'FFFF is set in TGR.
