Contention between General Register Write and Input Capture
If an input capture signal occurs in the T
priority and the write to the general register is not performed. See figure 10.68.
Note on Waveform Period Setting
When a counter is cleared by compare match, the counter is cleared in the last state at which the
TCNT value matches the general register value, at the time when this value would normally be
updated to the next count. The actual counter frequency is therefore given by the following
formula:
