Scroll Control (RA)
SN1-0:
Specify the display start line output from COM1. The data is displayed sequentially from the first
line to the fourth line then repeated from the first line.
SL3–0:
Select the top raster-row to be displayed (display-start raster-row) in the display-start lines
specified by SN1 to SN0. Any raster-row from the first to fourth can be selected. This function is used to
achieve raster-row-unit vertical smooth scrolling together with SN1 to SN0. For details, see the Vertical
Smooth Scroll section.
