Chroma error signal bypass. When HIGH, bypasses chroma error signal.

XLUT filter enable. When HIGH, enables the LPF on the XLUT output.

Adaption speed select. When HIGH, the 3 line comb filter selects between

comb filter architectures on a pixel by pixel basis. When LOW, the selection

is filtered.

Luma weighting bypass. When HIGH bypasses the luma fail weighting.
