Note:
- The peripheral function indicated in this column is based on the reference design. This is one of the possibilities as each ATSAMR30E18A pin supports several multiplexed peripheral functions mentioned in the Pin description column.
- Only these pins can be used for the SERCOM I2C mode: PA08, PA09, PA16 and PA17.
- This function is only activated in the presence of a debugger.
