Remarks
VBUS (5 V typical) USB supply generated by the host must
be connected to this input pin to enable the USB interface.
If the USB interface is not used by the Application Processor,
Test-Point for diagnostic / FW update access is recommended
See section 1.9.2 for functional description.
See section 2.6.2 for external circuit design-in.
USB interface for AT commands, data communication,
FOAT, FW update by u-blox EasyFlash tool and diagnostic.
90  nominal differential impedance (Z
30  nominal common mode impedance (Z
Pull-up or pull-down resistors and external series resistors as
required by the USB 2.0 specifications [9] are part of the
USB pin driver and need not be provided externally.
