PAL Comb Filter Settings
These settings are 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
PAL chroma comb adapts five lines (five taps) to
four lines (four taps); cancels cross luma and hue
error well
Configuration
Adaptive three-line
(three taps) luma comb
Use low-pass/notch
filter; see the Y Shaping
Filter section
Fixed two-line (two
taps) luma comb
Fixed three-line (three
taps) luma comb
Fixed two-line (two
taps) luma comb
