Contention between TCNT Write and Counter Clearing by Overflow: With channel 0 to 5

and 11 free-running counters (TCNT0, TCNT1A, TCNT1B, TCNT2A, TCNT2B, TCNT3 to

TCNT5, TCNT11), if overflow occurs in the T2 state of a CPU write cycle, the write to TCNT has

priority and TCNT is not cleared.

Writing of 1 to the interrupt status flag (OVF) due to the overflow is performed in the same way as

for normal overflow.

The timing in this case is shown in figure 10.66. In this example, H'5555 is written at the point at

which TCNT overflows.
