RX Polarity Inversion
Use the RX 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 polarity inversion, select the Enable
RX data polarity inversion option in the Gearbox section of Qsys. It can also be dynamically controlled
with dynamic reconfiguration.
