1. The min VILand max VIH values are based on the respective min and max USB_HVIN values found in Table 3.
2. The symbol USB_HVIN, in this case, represents the USB_HVIN symbol referenced in Recommended operating conditions
3. For recommended operating conditions, see Table 3
4. These specifications only apply to the following pins: USB1_PWRFAULT, USB2_PWRFAULT, USB1_UDM (full-speed
mode), USB2_UDM (full-speed mode), USB1_UDP (full-speed mode), and USB2_UDP (full-speed mode).
5. This specification only applies to USB1_DRVVBUS and USB2_DRVVBUS pins.
