The path from a module pin to device pad(s) is defined at the device I/O logic level. The control module registers assign the specific function to the device pads. For more information on control module settings, see Pad Configuration Registers in Control Module.
USB3 (ULPI) must not be used. Its functionality is not supported for this family of devices. This feature is subject to removal without notice on future device revisions. Any information regarding the unsupported feature is retained in the documentation solely for the purpose of clarifying signal names or for consistency with previous feature descriptions.
