7-13-3 Horizontal Scrolling
7-13-4 Bi-directional Scrolling
The display can be scrolled horizontally in one-character units, regardless of the display memory
capacity.
Bi-directional scrolling can be performed only if the display memory is larger than the physical
screen both horizontally and vertically. Although scrolling is normally done in single-character
units, the HDOT SCR command can be used to scroll horizontally in pixel units. The Single-pixel
scrolling of both horizontally and vertically can be performed by using the SCROLL and HDOT
SCR commands. See Section 17-4.
