PAL Comb Filter Settings
Used for PAL B/G/H/I/D, PAL M, PAL Combinational N,
PAL 60, and NTSC 4.43 CVBS inputs.
PSFSEL[1:0], Split Filter Selection PAL, Address 0x19 [1:0]
The PSFSEL[1:0] control selects how much of the overall signal
bandwidth is fed to the combs. A wide split filter selection
eliminates dot crawl, but shows imperfections on diagonal lines.
The opposite is true for selecting a narrow bandwidth split filter.

Description
Do not use
PAL chroma comb adapts five lines (three taps)
to three lines (two taps); cancels cross luma only
PAL chroma comb adapts five lines (five taps) to
three lines (three taps); cancels cross luma and
hue error less well

four lines (four taps); cancels cross luma and hue
error well
