FX3 power removed on IO
I want to use the FX3 superspeed explorer board in a design. But I want to power the FX3 IO from the board that the exploder is plugged into. So the VBUS would come from the USB connector and the IO from the motherboard. But there could be a situation where the IO voltage is turned off but the VBUS would still be on from the connector. So is it OK to do this?
