Contention between Counter Clearing by Input Capture and Counter Increment: If an input
capture signal and counter increment signal occur simultaneously, the counter is cleared according
to the input capture signal. The counter is not incremented by the increment signal. The value
before the counter is cleared is transferred to the general register. See figure 9.43.
