The receive buffers for the serializers (RBUF0) hold data from the serializer before the data goes to the receive format unit. For receive operations, the RBUF0 is an alias of the XRBUF0 in the serializer. Accessing XBUF registers not implemented on a specific device may cause improper device operation.
