19.4.12 Scroll Display
By setting display area and display screen sizes and start positions independently for each plane,
smooth scroll processing can be performed independently for each plane.
The display can be scrolled by cyclically setting the plane n display start position X, Y values
(coordinates specified by PnSPXR and PnSPYR), taking as the origin the leading address in
memory specified by PnDSA0R and PnDSA1R for each plane.
Figure 19.9 summarizes display scrolling. The display is scrolled by setting the display start
position from A to B.
Note: Display sizes and other area settings for each plane should be set such that there is no data
