LINE_VALID [1:0]
W
3
Determines the lines to be measured
00 = reserved
01 = only passes even occurrences of lines for measurements
10 = only passes odd occurrences of lines for measurements
11 = passes all occurrences of lines for measurements

INPUT_FORMAT_UV
W
0
UV input range type selector:
0 (unsigned) = 0 (minimum)
32 (negative, 100% saturation)
256 (uncolored)
480 (positive, 100% saturation)
511 (maximum)
1 (signed) = -256 (minimum)
-224 (negative, 100% saturation)
0 (uncolored)
224 (positive, 100% saturation)
255 (maximum)
5
INPUT_FORMAT_Y
W
0
Y input range type selector:
0 (unsigned) =
0 (minimum)
32 (black)
470 (white, 100%)
511 (maximum)
1 (signed)
= -256 (minimum)

4:3
OUTPUT_FORMAT_UV
[1:0]
W
0
UV output type selector
00 = Output is 9 bit, with LSB xed to 0 (true 8 bit)
01 = Output is 9 bit, with LSB copied from LSB + 1
10 = Output is 9bit, from undithered 8 bit
11 = Output is true 9 bit
The output range is always interpreted as signed
