LDLAOR sets the address width of the Y-coordinates increment used for LCDC to read the image
recognized by the graphics driver. This register specifies how many bytes the address from which
data is to be read should be moved when the Y coordinates (vertical direction) have been
incremented by 1. This register does not have to be equal to the horizontal width of the LCD
panel. When the memory address of a point (X, Y) in the two-dimensional image is calculated by
Ax + By+ C, this register becomes equal to B in this equation.
Bits 15 to 0—Line Address Offset (LDLAOR)
Notes: 1. The minimum alignment unit of LDLAOR is four bytes. Because the LCDC handles
