Abstract
A plurality of parity bits is generated for serial transmission of a word of data bits, and the plurality of parity bits is modified before transmission to encode a sideband signal. The word of data bits and the plurality of modified parity bits are serially transmitted. In another embodiment, a serially-transmitted code word comprising a word of data bits and a plurality of parity bits is received, wherein the parity bits have been generated by an encoder and transmitted with the data bits. It is determined whether the parity bits were modified by the encoder to encode a sideband signal, and at least one of error detection and error correction is performed using the parity bits.
