Configuration of DTP/External Interrupt

This section lists and details the pins, interrupt factors, and registers in the DTP/
external interrupt.
Pins of DTP/External Interrupt
The pins used by the DTP/external interrupt serve as general-purpose I/O ports.
Table 17.3-1 lists the pin functions and the pin setting required for use in the DTP/external interrupt.
