Functional overview

–The VDDUSB rising and falling time rate specifications must be respected

–

In the operating mode phase, VDDUSB could be lower or higher than VDD:

- If the USB (USB OTG_HS/OTG_FS) is used, the associated GPIOs powered by

VDDUSB are operating between VDDUSB_MIN and VDDUSB_MAX.

- The VDDUSB supplies both USB transceiver (USB OTG_HS and USB OTG_FS).

If only one USB transceiver is used in the application, the GPIOs associated to the

other USB transceiver are still supplied by VDDUSB.

- If the USB (USB OTG_HS/OTG_FS) is not used, the associated GPIOs powered

by VDDUSB are operating between VDD_MIN and VDD_MAX.
