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.
