Pins or Pads on unused interfaces can typically be left unconnected, unless otherwise stated. Many of the IOs have a Pad Configuration Register that provides control over the input capabilities of the IO (RXENABLE field in each conf_<module>_<pin> register). For more details, refer the Control Module chapter of the device-specific TRM. Software can disable the IO receive buffers (that is, RXENABLE=0) that are not connected in the design as soon as possible during initialization. Software needs to be ensure that it does not accidentally enable the receiver of an IO (by setting the RXENABLE bit) when the associated pin is floating.
