Connection of VREFP and VREFN pins in XC7A35T-FTG256

Jump to solution

What should I do with  VREFP and VREFN pins in XC7A35T-FTG256, if I don't use XADC? VCCADC and GNDADC pins were connected as shown in Arty board schematics. (I'm doing almost all connections as same as in Arty board schematic).
