2.9.1.8. RX Data Polarity Inversion

Use the RX data polarity inversion feature to swap the positive and negative signals of a serial differential link if they were erroneously swapped during board layout. To enable RX data polarity inversion, select the Enable RX data polarity inversion option in the Gearbox section of Platform Designer (Standard). It can also be dynamically controlled with dynamic reconfiguration. The Enhanced PCS only supports the static polarity inversion feature.
