Note: 
1. Pins names are of type Pxn, with x being the PORT instance (A,B) and n the pin number. Notation for signals is PORTx_PINn. All pins can be used as event input. 2. All pins can be used for external interrupt, where pins Px2 and Px6 of each port have full asynchronous detection.
Tip: 
Signals on alternative pin locations are in typewriter font. © 2017 Microchip Technology Inc.
