Note:
  1. Pin names are of type Pxn, with x being the PORT instance (A, B) and n the pin number. The 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 section 15 PORTMUX - Port Multiplexer.
  4. Alternate pins for SPI MISO and MOSI are respectively at PA7 and PA6 for 14-pin devices and PC1 and PC2 for 20-pin devices.
