–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.
