Note:
- 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.
- All pins can be used for external interrupt, where pins Px2 and Px6 of each port have full asynchronous detection.
- Every PTC line can be configured as X-line or Y-line.
Tip: Signals on alternative pin
locations are in typewriter font.
