Characteristics
mode after power on
RGB reference pulse position
adjustable,
guard band adjustable
Vertical aspect controls
zoom factor,
clipping of VD+, VD-, E/W
when NCLP = 0
as above,
Vertical scroll can be additio-
nally used for adjustment of
vertical position
Vertical aspect = -68
causes V-reduction to 66%,
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
vertical aspect = -102
causes V-reduction to 50%,
JMP = 0 causes V-shrink incl.
flyback
