22.2.3. Assigning Port I/O Pins to External Digital Event Capture Functions
External digital event capture functions can be used to trigger an interrupt or wake the device from a low
power mode when a transition occurs on a digital I/O pin. The digital event capture functions do not require
dedicated pins and will function on both GPIO pins (XBR0 = 1) and pins in use by the crossbar (XBR0 = 0).
External digital event capture functions cannot be used on pins configured for analog I/O. Table 22.3
shows all available external digital event capture functions.
