Note:
  1. Signal = ‘PIO’ if GPIO; Dir = Direction; PU = Pull-up; PD = Pull-down; HiZ = High impedance; ST = Schmitt Trigger
  2. This feature is fixed due to the SAM9X75 SOM Series internal connection.
  3. Compared to SAM9X75 SiP, this feature is limited, as it is partly used for other SAM9X75 SOM Series features, for example GMAC or FLEXCOM.
