Luminance filter stop band bandwidth (MHz):

00 = No notch (default)

01 = Notch 1

10 = Notch 2

11 = Notch 3

Luminance filter select [1:0] selects one of the four chroma trap (notch) filters to produce luminance signal by

removing the chrominance signal from the composite video signal. The stopband of the chroma trap filter is centered

at the chroma subcarrier frequency with stopband bandwidth controlled by the two control bits. Please refer to the

following table for the stopband bandwidths. The WCF bit is controlled in the chrominance control #2 register, see

Section 2.20.26.
