Section 25 LCD Controller
For example, the registers have been set up for the display of image data in landscape format (320
× 240), which starts from LDSARU = 0x0c001000, on a 320 × 240 LCD panel. The graphics
driver software is complete. Some changes are required to apply hardware rotation and use the
panel as a 240 × 320 display. If LDLAOR is 512, the graphics driver software uses this power of 2
as the offset for the calculation of the addresses of Y coordinates in the image data. Before setting
ROT to 1, the image data must be redrawn to suit the 240 × 320 LCD panel. LDLAOR will then
be 256 because the size has changed and the graphics driver software must be altered accordingly.
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

1) Normal mode
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.
