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