Notes:
41. 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
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 (BYTE8/10 is LOW and TXSC/D or RXSC/D is LOW)—TXDATA/RXDATA[8], [7], [6], [5], [4], and TXDATA/RXDATA[9], [3], [2], [1], [0].
42. 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 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.
43. Encoded Serial Symbol bits are shifted out with the most significant bit (Left-most) of the most significant nibble coming out first.
