USB 2.0 OTG PHY
The board provides USB interfaces using the SMSC USB3300 controller. A SMSC
USB3300 device in a 32-pin QFN package device is used to interface to a single Type
AB Micro-USB connector. This device supports UTMI+ Low Pin Interface (ULPI) to
communicate to USB 2.0 controller in HPS. As defined by OTG mode, the PHY can
operate in Host or Device modes. When operating in Host mode, the interface will
supply the power to the device through the Micro-USB interface.
