Claim 6:
7. A system 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 system comprising:
an encoder receiving a byte enable vector and an input data word, and the encoder configured to determine a set of selected data values to be sent over the data bus in selected data bit groups by using the byte enable vector to convert the input data word into a bit vector, the bit vector having a plurality of bit positions corresponding to the set of selected data values; and
a data word formatter receiving the bit vector from the encoder and configured to determine selected and non-selected data bit groups, to determine a code from the bit vector, the code representing a non-selected data value not included in the set of selected data values, to provide to a receiver device over the data bit lanes an output data word having the selected data values in the selected data bit groups and the code in non-selected data bit groups, and to provide the code to the receiver device over a plurality of code bit lanes separate from the data bit lanes.
