DTP/External Interrupt Circuit Pins

This section describes the DTP/external interrupt circuit pins and provides a pin block
diagram.
■ DTP/external Interrupt Circuit Pins
The DTP/external interrupt circuit pins are also used as general ports. Table 18.3-1 lists the pin functions,
I/O formats, and settings required to use the DTP/external interrupt circuit.
