At the end of the lines there are 2 possibilities:
(i) First (Start of Frame) line: Frame Count (Fc7: MSB)
Fc7 Fc6 Fc5 Fc4 Fc3 Fc2 Fc1 Fc0
00000111
Nibble D3 = FH
Nibble D2
(ii) All other lines: Line Average (Av7 MSB)
Av7 Av6 Av5 Av4 Av3 Av2 Av1 Av0
Nibble D1

00000111
Nibble D3 = FH
Nibble D2
Nibble D1
Nibble D0
The line code absolute value depends on whether 5-wire or 4-wire output mode has been selected,
as shown in Table 3.
