This section describes contention and other matters requiring special attention during 16-bit timer
operations.
Contention between 16TCNT Write and Clear: If a counter clear signal occurs in the T
a 16TCNT write cycle, clearing of the counter takes priority and the write is not performed. See
figure 8.37.
