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. 2. All pins can be used for external interrupt, where pins Px2 and Px6 of each port have full asynchronous detection. 3. Alternate pin positions. For selecting the alternate positions, refer to the PORTMUX documentation. ATmega3208/4808 – 32-pin Data Sheet I/O Multiplexing and Considerations © 2018 Microchip Technology Inc.
