4.1.3 Dynamic Reconfiguration Interface

Dynamic Reconfiguration Interface (DRI) performs the run time configuration of transceiver PMA/PCS, PCIe, CCC, and Transmit PLLs after initialization.

In this demo design, DRI is used for performing run time calibration of transceiver and CCC. Q2_LANE0 is enabled to expose slave to the Transceiver Interface, as shown in the following figure.
