9.3.1.1 ULPI Interface Settings

For configuring the USB OTG controller to use with the ULPI PHY, the interface option can be selected as shown in the following figure. For interfacing the USB OTG controller with ULIP PHY, the USB MSIO signals are connected to four separate mutually exclusive I/O groups: USBA, USBB, USBC, and USBD I/O. In the M2S050 devices, only the USBD I/O group is available. Where in M2S025 and M2S010, only the USBA, USBB, and USBC I/O groups are available. Based on the SmartFusion 2 device selected, the I/O groups can be selected from the USB configurator.
