question regarding usb i/o supply in stm32f779ni

Hello,

Please consider the following scenario.

Let’s say we need different voltage for USB i/o’s. So VDD_USB pin is supplied with separate Vdd_usb supply.

Now irrespective of which alternate function in use, does the i/o’s operate in Vdd_usb voltage or only if the USB related alternate functions are chosen, then they do so ?

Regards,

Bivin
