Section 10 Advanced Timer Unit (ATU)
Contention between TCNT Write and Increment: If a write to a channel 0 to 9 free-running
counter (TCNT0 to TCNT9) is performed while that counter is counting up, the write to the
counter has priority and the counter is not incremented.
The timing in this case is shown in figure 10.55. In this example, the CPU writes H'5555 at the
point at which TCNT is to be incremented from H'1001 to H'1002.
