Luminance filter select [1:0] selects one of the four chrominance trap (notch) filters to produce luminance
signal by removing the chrominance signal from the composite video signal. The stopband of the
chrominance trap filter is centered at the chrominance subcarrier frequency with stopband bandwidth
controlled by the two control bits. See the following table for the stopband bandwidths. The WCF bit is
controlled in the chrominance control #2 register, see Section 3.21.25.
