Functional overview
than V_DD
– The V_DDUSB rising and falling time rate specifications must be respected
– In the operating mode phase, V_DDUSB could be lower or higher than V_DD:
- If the USB (USB OTG_HS/OTG_FS) is used, the associated GPIOs powered by
V_DDUSB are operating between V_{DDUSB_MIN} and V_{DDUSB_MAX}.
- The V_DDUSB 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 V_DDUSB.
- If the USB (USB OTG_HS/OTG_FS) is not used, the associated GPIOs powered
by V_DDUSB are operating between V_{DD_MIN} and V_{DD_MAX}.
