Section 17 16-Bit Timer Pulse Unit (TPU)
Contention between Overflow/Underflow and Counter Clearing: If overflow/underflow and
counter clearing occur simultaneously, the TCFV/TCFU flag in TSR is not set and TCNT clearing
takes precedence.
Figure 17.52 shows the operation timing when a TGR compare match is specified as the clearing
source, and H'FFFF is set in TGR.
