184.108.40.206. RX Polarity Inversion
Receiver polarity inversion can be enabled in low latency, basic, and basic rate match modes. The Standard PCS supports both the static and dynamic polarity inversion features.
To enable the RX polarity inversion feature, select the Enable RX polarity inversion and Enable rx_polinv port options.
This mode adds rx_polinv. If there is more than one channel in the design, rx_polinv is a bus in which each bit corresponds to a channel. As long as rx_polinv is asserted, the RX data received has a reverse polarity.
You can verify this feature by monitoring rx_parallel_data.
