A method and apparatus for encoding and decoding data. A primary data channel comprising a parallel data word has a bit of a secondary data channel associated with the parallel data word. ECC bits are generated based upon the parallel data word and the monitor bit and the ECC bits are appended to the data comprising the primary and secondary channel data to form an extended width parallel word. The extended width parallel data word is divided into a plurality of lesser width data words which are each scrambled using respective side scrambler for form respective cipher data words. An ECC control bit and a parity bit is generated for each channel, and associated with the cipher data words to form extended cipher data words. The cipher data words are serialized and transmitted over a serial link. The received serial data is deserialized, word framed and word aligned across the respective channels, and descrambled to obtain the data contained in the primary and secondary data channels. ECC is provided both on data and control bits to permit error correction on either the data or control information.
