8B/10B Serial Output Format

The 8B/10B encoding translates a 8-bit parallel data byte to be transmitted into a 10-bit
serial data stream. This conversion and data alignment are shown in
port transmits the least significant bit of the 10-bit data "a" first and proceeds to "j". This
allows data to be read and matched to the form shown in
