Note:
Used for setting HS transmit current level and on-
chip termination impedance. Connect to an
external 12K 1.0% resistor to ground.
This pin must be connected to VDDCORE for
proper operation.

The functionality of this pin may be
swapped to USB DPLUS via the
PORT_SWAP configuration strap.
The functionality of this pin may be
swapped to USB DMINUS via the
PORT_SWAP configuration strap.
This pin can also be driven by a single-
ended clock oscillator. When this
method is used, XO should be left
unconnected
