Reserved 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):
