2.9.2.4. RX Polarity Inversion
Receiver polarity inversion can be enabled in low latency, basic, and basic rate match
modes.
To enable the RX polarity inversion feature, select the Enable RX polarity inversion
and Enable rx_polinv port options.
This mode adds
rx_polinv
rx_polinv
You can verify this feature by monitoring

. 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
is asserted, the RX data received has a reverse polarity.
