If enabled, after detection of a valid edge on input capture pin, the delay
counter counts the pre-selected number of M clock (module clock)
cycles, then it will generate a pulse on its output. The pulse is generated
only if the level of input signal, after the preset delay, is the opposite of
the level before the transition.This will avoid reaction to narrow input
pulses.
After counting, the counter will be cleared automatically.
Delay between two active edges of the input signal period should be
longer than the selected counter delay.
