    Enable Vref/Vssa






      Does the Enable Vref/Vssa option in the ADC's Common tab allow us to connect a variable reference in PSoC schematic (rather than allocating a special pin to acquire an external Vref?

          I think this targets removing offset when an external reference, using


          a pin, is selected. And I think datasheet accuracy is written around that


          assumption. It might be possible to actually use pin as a variable reference,


          I would file a CASE to ask if done that keeps datasheet accuracy or that


          pin absolutely must be very close to ground level.
