DATASHEET
7.1.1.8 USB Interrupt Enable Rising
Address = 0D-0Fh (read), 0Dh (write), 0Eh (set), 0Fh (clear)
7.1.1.9 USB Interrupt Enable Falling
Address = 10-12h (read), 10h (write), 11h (set), 12h (clear)
DrvVbusExternal 6 rd/w/s/c 0b 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.
UseExternalVbus
Indicator
7 rd/w/s/c 0b Tells the transceiver to use an external VBUS over-
current or voltage indicator. This function is detailed
in Section 5.6.2.
0b: Use the internal VbusValid comparator
1b: Use the EXTVBUS input as for VbusValid signal.
Note: The EXTVBUS signal is always high on the
USB3320.
