Num
This is the shortest pulse guaranteed to pass through the pin input filter circuitry. Shorter pulses may or may not be recognized.
This is the minimum pulse width that is guaranteed to pass through the pin synchronization circuitry. Shorter pulses may or
may not be recognized. In stop mode, the synchronizer is bypassed so shorter pulses can be recognized in that case.
Timing is shown with respect to 20% V
