Used for PAL-B/G/H/I/D, PAL-M, PAL-Combinational N,
PAL-60 and NTSC-443 CVBS inputs.

PSFSEL[1:0] Split Filter Selection PAL, Address 0x19 [1:0]
PFSEL[1:0] selects how much of the overall signal bandwidth is
fed to the combs. A wide bandwidth split filter eliminates dot
crawl, but shows imperfections on diagonal lines. The opposite
is true for a narrow bandwidth split filter.

Description
00
Do not use.
01
PAL chroma comb adapts 5 lines (3 taps) to
3 lines (2 taps); cancels cross luma only.
10
PAL chroma comb adapts 5 lines (5 taps) to
3 lines (3 taps); cancels cross luma and hue error
less well.
11 (default)
PAL chroma comb adapts 5 lines (5 taps) to
4 lines (4 taps); cancels cross luma and hue error
well.

Each vertical blank control register has the same meaning for
the following bits:
00—Early by 1 line.
10—Delay by 1 line.
11—Delay by 2 lines.
01 (default) is described under each register.
NVBIOLCM[1:0] NTSC VBI Odd Field Luma Comb Mode,
Address 0xEB [7:6]

Address 0xEB [3:2]
These bits control the first combed line after VBI on PAL odd
field (luma comb).
01 (default)—BT470 compliant, blank lines 624 to 22, 311 to
335, comb half lines.
PVBIELCM[1:0] PAL VBI Even Field Luma Comb Mode,
