Claim 18:
19. A method for data communication over a data bus having a plurality of data bit groups, each data bit group having a plurality of data bit lanes, the method comprising:
receiving, by a receiver device, a code separately from the data bit lanes over code bit lanes;
receiving, by the receiver device, a first data word having data values over the data bit lanes of the data bus;
comparing, by comparators in the receiver device, the code with the first data word having each data value in each data bit group received over the data bus;
determining, by the receiver device, each data bit group having a data value matching the code;
determining, by the receiver device, each data bit group having a data value not matching the code;
generating a byte enable vector from the first data word and code with the receiver device, the byte enable vector comprising indications of selected data bit groups based on determinations of data bit groups having data values matching the code and indications of non-selected data bit groups based on determinations of data bit groups having data values not matching the code; and
reconstructing a second data word based on the byte enable vector.
