Caution When the input port pins used for the external interrupt functions are switched to the output mode,
the INTPn interrupt might be generated upon detection of a valid edge.
When switching the input port pins to the output mode, set the port mode register (PMxx) to 0 after
disabling the edge detection (by setting EGPn and EGNn to 0).
Remarks 1. For edge detection port, see 2.1 Port Function.
2. n = 0 to 11
