Trap filter select [1:0]
Trap filter select[1:0]:
Selects one of the four trap filters to produce the luminance signal by removing the chrominance signal from the composite video
signal. The stop band of the chroma trap filter is centered at the chroma subcarrier frequency with the stop-band bandwidth controlled
by the two control bits.
Trap filter stop band bandwidth (MHz):

Brightness [7:0]
Brightness [7:0]:
This register works for CVBS and S-Video luminance.
0000 0000 = 0 (dark)
1000 0000 = 128 (default)
1111 1111 = 255 (bright)
For composite and S-Video outputs, the output black level relative to the nominal black level (64 out of 1024) as a function of the
Brightness[7:0] setting is as follows.
Black Level = nominal_black_level + (MB + 1) × (Brightness[7:0] – 128)
Where MB is the brightness multiplier setting in the Brightness and Contrast Range Extender register at I
2C subaddress 2Fh.
