Contention between General Register Write and Input Capture: If an input capture signal
occurs in the T
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:
