This analog input pin senses the level of the USB VBUS
voltage and should connect directly to the USB VBUS
voltage. When the USB0 PHY is powered down, this pin
should be left unconnected.
When this pin is used as USB0_DRVVBUS and the
USB0 Controller is operating as a Host, this signal is
used by the USB0 Controller to enable the external
VBUS charge pump.
When the USB0 PHY is powered down, this pin should
be left unconnected.

When this pin is used as USB1_DRVVBUS and the
USB1 Controller is operating as a Host, this signal is
used by the USB1 Controller to enable the external
VBUS charge pump.
When the USB1 PHY is powered down, this pin should
be left unconnected.
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal, MM = Multi Muxed, DSIS = De-
selected Input State
(2) IPD = Internal Pulldown Active, IPU = Internal Pullup Active, DIS = Internal Pull Disabled. This represents the default state of the
Internal Pull after Reset. For more detailed information on pullup/pulldown resistors and situations where external pullup/pulldown
resistors are required, see Section 5.5.1, Pullup/Pulldown Resistors and Section 8.3.17, Pin Behaviors at Reset.
(3) Specifies the operating I/O supply voltage for each signal
