LDSARU sets the start address from which data is fetched by the LCDC for display of the LCDC
panel. When a DSTN panel is used, this register specifies the fetch start address for the upper side
of the panel. The register setting is updated with the Vsync timing when the LCDC is active.

the image which can be calculated from the display image size in this register. The
equation below shows how to calculate the LDSARU value when the image size is 240
× 320 and LDLAOR = 256. The LDSARU value is obtained not from the panel size but
from the memory size of the image to be displayed. Note that LDLAOR must be a
binary exponential at least as large as the horizontal width of the image. Calculate
backwards using the LDSARU value (LDSARU − 256 (LDLAOR value) × (320 − 1)) to
ensure that the upper-left address of the image is aligned with the 512-byte boundary.
LDSARU = (upper-left address of image) + 256 (LDLAOR value) × 319 (line)
