Note:
- Pin names are of type Pxn, with x being the PORT instance (A,B,C, ...) and n the pin number. Notation for signals is PORTx_PINn. All pins can be used as event input.
- All pins can be used for external interrupt, where pins Px2 and Px6 of each port have full asynchronous detection.
- Alternate pin positions. For selecting the alternate positions, refer to the PORTMUX documentation.
