3. LDLAOR should be power of 2 (when the horizontal width after rotation is 240 pixels,
4. Graphics software should be set up for the number 3 setting.
5. LDSARU should be changed to represent the address of the data for the lower-left pixel of the
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.
