5.3. RX PMA Adaptation

The RX PMA Adaptation mode is pre-configured for each line rate during the IP generation. The following table lists the most optimal mode for each line rate. In auto-adaptation, the PMA performs dynamic adaptation on the RX link. In manual adaptation, there is no dynamic adaptation; you can tune the RX link using the static equalization taps.
