9.5. Scrolling
The controlling microprocessor can set the S1D13305
series scrolling modes by overwriting the scroll address
registers SAD1 to SAD4, and by directly setting the
scrolling mode and scrolling rate.
9.5.1. 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.
9.5.2. Inter-page scrolling
Scrolling between pages and page switching can be
performed only if the display memory capacity is greater
than one screen.

Since the S1D13305 series does not automatically erase
the bottom line, it must be erased with blanking data when
changing the scroll address register.
