Note:
  1. All analog pin functions are on the peripheral function B. The peripheral function B must be selected to disable the digital control of the pin. The AC has analog signals on the peripheral function B and digital signals on the peripheral function M.
  2. Refer to TCC Configuration Summary table for the list of supported features for each peripheral instance.
  3. I²C is not supported on all SERCOM pins. Refer to SERCOM I2C Pinout table for the list of supported features for each peripheral instance.
  4. The following High-Sink pins have different properties than the regular pins: PA08, PA09, PA12, PA13, PA16, PA17, PA22, and PA23.
