DrvVbus 5 0b 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
DrvVbusExternal 6 0b 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
UseExternalVbus
Indicator
7 0b Tells the PHY to use an external VBUS over-current or voltage
indicator. This function is detailed in Section 6.5.4, "External
Vbus Indicator".
0b: Use the internal VbusValid comparator
1b: Use the EXTVBUS input as for VbusValid signal.

from low to high.
SessValid Rise 2 1b Generate an interrupt event notification when SessValid changes
from low to high.
SessEnd Rise 3 1b Generate an interrupt event notification when SessEnd changes
from low to high.
IdGnd Rise 4 1b Generate an interrupt event notification when IdGnd changes
from low to high.
Reserved 7:5 0h Driven low.
FIELD NAME BIT DEFAULT DESCRIPTION
