Writing a Dual Scan value to this bit selects whether the
display is used in single scan mode, or dual scan mode
where the display is divided into a ‘top’ half and a ‘bottom’
half. In dual scan mode, the video frame buffer in SDRAM
must be organized such that ‘top’ and ‘bottom’ pixels
alternate in consecutive locations. ‘Top’ and ‘bottom’ pixels
are fetched and input to the Raster Engine’s video
pipeline. The output shifter is set up to drive the top and
bottom half screen data at the same time. Dual scan mode
is intended for passive matrix LCD screens that require
both halves of the screen to be scanned out at the same
time. However, dual scan mode could also be used to
drive two separate synchronized displays, each with
different data.
