Note:
  1. The package XCB (128-pin TQFP) has an exposed pad that is an additional ground. This must be soldered to the board's ground plane to provide additional noise immunity and thermal dissipation.
  2. 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.
  3. Refer to the TCC Configuration Summary table for the list of supported features for each peripheral instance.
  4. I²C is not supported on all SERCOM pins. Refer to the SERCOM I²C Pinout table for the list of supported features for each peripheral instance.
  5. The following High-Sink pins have different properties than the regular pins: PA08, PA09, PA12, PA13, PA16, PA17, PA22, PA23, PD08, and PD09.

Note:
  1. The package XCB (128-pin TQFP) has an exposed pad that is an additional ground. This must be soldered to the board's ground plane to provide additional noise immunity and thermal dissipation.
  2. 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.
  3. Five I/O pins (PB26, PB27, PB28, PB29 and PC04) are not connected as reserved for the HSM interconnection.
