PAL Comb Filter Settings
Used for PAL-B/G/H/I/D, PAL-M, PAL-Combinational N,
PAL-60 and NTSC443 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 5 lines (3 taps) to
3 lines (2 taps); cancels cross luma only.
PAL chroma comb adapts 5 lines (5 taps) to
3 lines (3 taps); cancels cross luma and hue error
less well.
PAL chroma comb adapts 5 lines (5 taps) to
4 lines (4 taps); cancels cross luma and hue error
well.
