16:9 CRT full
4:3 CRT full, amplitude: 1.23Vp-p
Scrolled toward top of screen by 32H and top of picture zoomed.
Scrolled toward bottom of screen by 32H and bottom of picture zoomed.
Sawtooth wave amplitude: 1.23Vp-p
Sawtooth wave amplitude: 70%
HBLK pulse generated from HPIN.
HBLK pulse generated as pulse generated from HPIN or as
pulse generated from HVCO and width adjusted.
Width adjustment is performed by the LEFT-BLK and
RIGHT-BLK registers.
Horizontal size for top of picture increases; horizontal size for
bottom of picture decreases.
8.9ms from 4VDC VTIM
Horizontal size for top of picture decreases; horizontal size
for bottom of picture increases.
