9.3.1.2 UTMI Interface Settings

If UTMI PHY is in use, then Microchip recommends selecting the UTMI interface in the USB configurator, as shown in the following figure. For interfacing the USB OTG controller with UTMI PHY, the interface signals are routed through the FPGA fabric onto the MSIOs. There is no separate I/O grouping like the ULPI interface has, for the SmartFusion 2 device variants to use with UTMI PHY.
