Many signals are available on multiple pins, according to the software configuration of the pin multiplexing options.
Texas Instruments has developed an application called Pin Mux Utility that helps a system designer select the appropriate pin-multiplexing configuration for their device-based product design. The Pin Mux Utility provides a way to select valid IOSETs of specific peripheral interfaces to ensure the pin multiplexing configuration selected for a design only uses valid IOSETs supported by the device.
