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 (PnSKIP = 1) and pins in use by the Crossbar (PnSKIP
= 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.

Any Port pin available for assignment by the
Crossbar. This includes P0.0 - P2.6 pins which
have their PnSKIP bit set to 0.
Note: The Crossbar will always assign UART0
pins to P0.4 and P0.5.
