Description
RGB ref. pulse position = line 20... 22 (odd field)
end of V-blanking = line 22 (odd field)
guard band = 1.5 lines
RGB ref. pulse position = line (RPP + 16)
...(RPP + 18) (odd field)
end of V-blanking = line (RPP + 18) (odd field)
guard band = Guard band/2 [lines]

Characteristics
mode after power on
RGB reference pulse position
adjustable,
guard band adjustable
Vertical scroll/Vertical aspect
for user defined V-position/V-
size,
WHITD disables RGB white
level ref. pulses
Vertical aspect = -50
causes V-reduction to 75%,
JMP = 0 causes V-shrink incl.
flyback
RGB ref. pulse positon adjust.,
JMP = 1 causes V-shrink excl.
flyback,
WHITD disables RGB white
level ref. pulses
guard band adjustable
