The point that corresponds to LDSARU moves from the upper left to the lower left of the display,

so LDSARU should be changed to 0x0c001000

+ 256 * 319.

Note:

Hardware rotation allows the use of an LCD panel that has been rotated by 90 degrees.

The settings in relation to the LCD panel should match the settings for the LCD panel

before rotation. Rotation is possible regardless of the drawing processing carried out by

the graphics driver software. However, the sizes in the image data and address offset

values which are managed by the graphics driver software must be altered.

Scanning starts from LDSARU.

Scanning is done from large address

to small address of Y coordination.
