The PCIe Requester Request (RQ)/Requester Completion (RC) interface generates PCIe TLPs on the RQ bus and processes PCIe Completion TLPs from the RC bus. This interface to the AMD Versal Adaptive SoC Integrated Block for PCIe® core operates in DWord aligned mode. With a 512-bit interface, straddling is enabled. While straddling is supported, all combinations of RQ straddled transactions might not be implemented. For further details, see the Versal Adaptive SoC Integrated Block for PCI Express LogiCORE IP Product Guide (PG343).
