XADC alternate GPIO function
If the XADC function is not desired, the port can be used for additional GPIO expansion
as necessary. However, care must be taken to ensure the appropriate logic voltage
levels are observed when using these signals. VCCIO_35 sets the acceptable voltage
levels for the XADC_GIOx signals. For AD*_P/N signals must be limited to 1.8V logic
levels.
The following signals can be used to perform digital GPIO functionality:
