Error Handling

The client can indicate an error response for a write request on the AXI master write response channel signals by asserting TARGET_AXI_BVALID and indicating an error code on the TARGET_AXI_BRESP signal. The PCIe Controller ignores the response type (i.e., good or bad) for a posted write request. For a non-posted write request, the PCIe Controller sends back a completer abort completion to the requester; otherwise, on receipt of a good response for a non-posted write request, PCIe Controller sends back a good completion to the requester.
