S1D13700 Technical Manual
The MPU dynamically rewrites the scroll address registers (SAD1–SAD4) that provide the read start address
in the S1D13700’s display memory, thereby allowing various scroll modes to be set. In this case, the MPU
manages all operations to execute scrolling, select scroll mode, and set a scroll rate.
(1) Intra-page scrolling
(2) Inter-page scrolling and page switching
Scrolling
This refers to a mode of scroll operation whereby scrolling is performed within display memory space
equivalent to one screen.
All lines are scrolled one line up and the bottom line is deleted as shown below. Since the S1D13700 does
not automatically delete the bottom line, the MPU must rewrite the scroll address registers and
simultaneously write blank data to the S1D13700.
Scrolling between pages and page switching can be performed only when display memory has more than
one-screen equivalent capacity.
