In single-width mode, the 8B/10B decoder decodes the received 10-bit code groups into an 8-bit data and a 1-bit control identifier, in compliance with Clause 36 in the IEEE 802.3 specification. The 1-bit control identifier indicates if the decoded 8-bit code is a valid data or special control code. The decoded data is fed to the byte deserializer or the receiver phase compensation FIFO (if the byte deserializer is disabled).
