There are 9 Control Codes (K-Codes) which are considered separately from the 7/8-5/6 encoding algorithm. If the dataKIn input is high, then the 14-bit output is selected from the following table below.

The normal output (Out 14b) is selected when the input disparity is -2. Otherwise the inverted output is selected. Control codes may get inverted even if their encoded disparity is 0.

...

If dataKIn is high and the input code is not in the table, then the output is in-determinantindeterminant.

SSP

The SLAC Streaming Protocol (SSP) 12b/14b implementation uses K.120.11 for IDLE (and alignment), K.120.0 for Start-of-Frame (SOF) and K.120.1 for End-of-Frame (EOF).
