NOTE)
1. If the same level is not detected on enabled pin three or four times in a row at the sampling clock, the
signal is eliminated as noise.
2. A pulse level should be input for the duration of 3 clock or more to be actually detected as a valid edge.
3. The port de-bounce is automatically disabled at stop mode and recovered after stop mode release.
4. Refer to the port 0 de-bounce enable register (P0DB) for the de-bounce clock of port 1 and port 5.
