DATASHEET
Used to enable external 5 volt supply to drive 5 volts on VBUS.
This signal is or’ed with DrvVbusExternal.
0b: do not drive VBUS
1b: drive VBUS
Used to enable external 5 volt supply to drive 5 volts on VBUS.
This signal is or’ed with DrvVbus.
0b: do not drive VBUS
1b: drive VBUS
Tells the PHY to use an external VBUS over-current or voltage
indicator. This function is detailed in
0b: Use the internal VbusValid comparator
1b: Use the EXTVBUS input as for VbusValid signal.
