The DRP interface allows user applications to monitor and modify the transceiver status. The native interface provides the native transceiver DRP interface ports. The AXI4-Lite interface (fully compliant with the AXI4-Lite protocol) is the default interface.

For native DRP sequences, the read and write operations are as specified in the respective FPGA Transceivers User Guides. For AXI4-Lite DRP sequences, the read and write operations from the user interface are specified in the AXI4-Lite protocol. The Aurora 64B/66B core does not use the wstrb signal (refer to the Vivado AXI Reference Guide , (UG1037) [Ref 10] ). The axi_to_drp module is used to translate between the transceiver DRP and AXI4-Lite protocols.
