Horizontal Smooth Scroll
The HD66724/HD66725 perform the horizontal smooth scroll in 3-dot units. In the character display mode
(GR = 0), an area of 16 characters x 5 lines is assigned as DDRAM. In the graphics display mode (GR =
1), a 96 x 32-dot area is assigned as CGRAM. These non-display areas are used to provide a horizontal
smooth scroll display. When the HD66725 displays 16 characters or 96 dots, there are no non-display areas
and horizontal scrolling cannot be done.
Display lines for horizontal scroll can be separately specified using the horizontal scroll bits (SE4-1),
allowing a scroll of the whole display or specified lines. Horizontal scroll dots can be specified using the
horizontal scroll dot bits (SQ2-0), allowing up to a 21-dot scroll at a time. For further scrolls, data in the
DDRAM or CGRAM must be overwritten.
