SED1330F Datasheet, PDF (90/148 Pages) List of Unclassifed Manufacturers – LCD Controller ICs

5.0 Display Control Functions
5.5 Scrolling
The controlling microprocessor can set the SED1330F/
1335F/1336F scrolling modes by overwriting the scroll
address registers SAD1 to SAD4, and by directly
setting the scrolling mode and scrolling rate.
5.5 – 5.5.1
5.5.1 On-page Scrolling
The normal method of scrolling within a page is to
move the whole display up one line and erase the
bottom line. Since the SED1330F/1335F/1336F does
not automatically erase the bottom line, it must be
erased with blanking data when changing the scroll
address register.
