Abstract: Data may be communicated from a sender device to a receiver device over enabled or selected byte positions or other data bit groups of a data bus. The sender device may determine data values to be sent over the data bus and may determine which byte positions are enabled or selected and which are not selected. The sender device may also determine a code. The code may be a value that is not included in the data values to be sent over the data bus. The sender device may then send the selected data values in selected byte positions of the data bus and send the code in non-selected byte positions of the data bus. The sender device may also send the code to the receiver device separately from the data bit lanes of the data bus.
