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. See Table 7-4 for the stopband bandwidths. The WCF bit is controlled in the chrominance
control #2 register.
