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 Mini-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 Mini-USB
interface.
Figure 3-26
shows the schematic diagram of the USB circuitry; the pin assignments for
the associated interface are listed in
Table 3-28
