Scrolls 13 raster-rows down
(Begins display from the first raster-row of the fourth line)
Scrolls 14 raster-rows down
(Begins display from the third raster-row of the 13th line)
Scrolls 26 raster-rows down
(Begins display from the third raster-row of the first line)
Note: The DDRAM has 80 bytes. For a 4-line display mode, a 4-line 10-character/line display can
therefore be performed. Although the line and raster-row for scrolling can be designated as
desired, the first raster-row of the first line will be displayed after displaying raster-row 13 of line 4.
