Cautions: 1. If the input pulse lasts for the duration of 4 to 5 clocks, it is undefined whether the
pulse is detected as a valid edge or eliminated as noise. So that the pulse is
actually detected as a valid edge, the same pulse level must be input for the
duration of 5 clocks or more.
2. If noise is generated in synchronization with the sampling clock, eliminate the
noise by attaching a filter to the input pin.
3. Noise is not eliminated if the corresponding pin is used as normal input port pin.
