Notes
39. Binary Input Data is the parallel input data which is input to the Transmitter and output from the Receiver. Binary bits are listed from left to right in the following
40. The ENCODED Symbols are shown here as “ones and zeros”, but are converted to and from an NRZI stream at the transmitter output and receiver input. NRZI
41. Encoded Serial Symbol bits are shifted out with the most significant bit (Left-most) of the most significant nibble coming out first.
42. Binary CMD is the parallel input data which is input to the Transmitter and output from the Receiver. Binary bits are listed from left to right in the following order:
43. While these Commands are legal data and will not disrupt normal operation if used occasionally, they may cause data errors if grouped into recurrent fields.

order: 8-Bit mode (BYTE8/10 is HIGH and TXSC/D or RXSC/D is LOW)—TXDATA/RXDATA[7], [6], [5], [4], and TXDATA/RXDATA[3], [2], [1], [0]; 10-Bit mode

represents a “one” as a state transition (either LOW-to-HIGH or HIGH-to-LOW) and a “zero” as no transition within the bit interval.
8-Bit mode (BYTE8/10 is HIGH and TXSC/D or RXSC/D is HIGH)—TXCMD/RXCMD[3], [2], [1], [0]; 10-Bit mode (BYTE8/10 is LOW and TXSC/D or RXSC/D
is HIGH)—TXCMD/RXCMD[1], [0].
Normal PLL operation cannot be guaranteed if one or more of these commands is continuously repeated.
