Section 10 16-Bit Timer Pulse Unit (TPU)
10.10.12 Conflict between TCNT Write and Overflow/Underflow
If an overflow/underflow occurs due to increment/decrement in the T2 state of a TCNT write
cycle, the TCNT write takes precedence and the TCFV/TCFU flag in TSR is not set.
Figure 10.54 shows the operation timing when there is conflict between TCNT write and
overflow.
