DESCRIPTION
Enables external 5 volt supply to drive 5 volts on
VBUS. This signal is or’ed with DrvVbus.
0b: Do not drive Vbus, CPEN driven low.
1b: Drive Vbus, CPEN driven high.
Tells the transceiver 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.
Note:
DESCRIPTION
Generate an interrupt event notification when
Hostdisconnect changes from low to high. Applicable
only in host mode.
Generate an interrupt event notification when
Vbusvalid changes from low to high.
Generate an interrupt event notification when
SessValid changes from low to high.
Generate an interrupt event notification when
SessEnd changes from low to high.
Generate an interrupt event notification when IdGnd
changes from low to high.
Read only, 0.
DESCRIPTION
Generate an interrupt event notification when
Hostdisconnect changes from high to low. Applicable
only in host mode.
Generate an interrupt event notification when
Vbusvalid changes from high to low.
Generate an interrupt event notification when
