°
(or landscape) is a mode in which both the main and sub-window are non-
rotated. The images for each window are typically placed consecutively, with the main
window image starting at address 0 and followed by the sub-window image. In addition,
both images must start at addresses which are dword-aligned (the last two bits of the
starting address must be 0).
Note
It is possible to use the same image for both the main window and sub-window. To do
so, set the sub-window line address offset registers to the same value as the main win-
dow line address offset registers.
Example 5:Program the main window and sub-window registers for a 320x240 pan-
el at 4 bpp, with the sub-window positioned at (80, 60) with a width of
160 and a height of 120.
1. Confirm the main window coordinates are valid.
The horizontal coordinates must be a multiple of 32
÷
bpp.

2. Confirm the sub-window coordinates are valid.
