Section 24 LCD Controller (LCDC)
24.3.7
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 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.

Description
Line Address Offset
The minimum alignment unit of LDLAOR is 16 bytes.
Because the LCDC handles these values as 16-byte
data, the values written to the lower four bits of the
register are always treated as 0. The lower four bits of
the register are always read as 0. The initial values (×
resolution = 640) will continuously and accurately place
the VGA (640 × 480 dots) display data without skipping
an address between lines. For details, see tables 24.4
and 24.5.
A binary exponential at least as large as the horizontal
width of the image is recommended for the LDLAOR
value, taking into consideration the software operation
speed. When the hardware rotation function is used,
the LDLAOR value should be a binary exponential (in
this example, 256) at least as large as the horizontal
width of the image (after rotation, it becomes 240 in a
240 × 320 panel) instead of the horizontal width of the
LCD panel (320 in a 320 × 240 panel).
