Note:
- Signal = ‘PIO’ if GPIO; Dir = Direction; PU = Pull-up; PD = Pull-down; HiZ = High impedance; ST = Schmitt Trigger
- This feature is fixed due to the SAMA7D65 SOM Series internal connection.
- Compared to SAMA7D65 SiP, this feature is limited, as it is partly used for other SAMA7D65 SOM Series features, for example GMAC or FLEXCOM.
