Status Flag Clearing Timing: The status flag is cleared when the CPU reads a 1 status followed
by a 0 write. Figure 8.38 shows the timing for status flag clearing by the CPU.
8.7
This section describes contention and other matters requiring special attention during MTU
operations.
Note on Cycle Setting: When setting a counter clearing by compare-match, clearing is done in the
final state when TCNT matches the TGR value (update timing for count value on TCNT match).
The actual number of states set in the counter is given by the following equation:
Contention between TCNT Write and Clear: If a counter clear signal is issued in the T
during the TCNT write cycle, TCNT clearing has priority, and TCNT write is not conducted
(figure 8.39).
