Display Interface Unit (DIU)
To achieve cursors with shapes other than the basic square, set the alpha value to 0 in those pixels that are
to be transparent. To make the cursor disappear, set the alpha value to 0 for all the pixels.
Similar to the palette and gamma, the cursor bitmap is also automatically loaded by the DIU from memory
into an embedded SRAM before it starts processing the next frame if the CPU writes to the CURSOR
register (See
256 × 64 bits.
The cursor position is determined by the register CURSOR_POS (See
Register
The cursor can be partially or totally off the screen.

Besides driving the LCD display, the DIU supports two operating modes (mode 2 and 3) with memory
writeback operation. Intermediate blending results are stored back into the memory (DDR DRAM). These
intermediate results can be then forwarded to other processing or display units or blended with other image
source(s) again in the DIU, virtually extending the number of graphics planes.
DIU mode 1 supports the blending and display of as many as three planes. If an application requires the
display of an image blended from four or more planes, this can be accomplished in DIU mode 2. Plane 1
is used to display one frame while the following frame is blended by the DIU. Planes 2 and 3 are used
initially to read in the first and second planes to be combined, and the DIU writes back a combined plane
1 + 2. Then, while the DIU displays the same frame on plane 1, the DIU reads back in on plane 2 the
intermediate plane 1 + 2, and on plane 3 the new third plane, writing back a combined plane 1 + 2 + 3.
Then (while the DIU displays the same frame on plane 1), the DIU reads back in on plane 2 the
intermediate plane 1 + 2 + 3, and on plane 3 the new fourth plane, writing back the combined plane
1 + 2 + 3 + 4. This combined plane is then ready to be displayed on plane 1 in the following frame, or extra
steps can be added to blend more than four planes.
The writeback pixel format is always 24-bit RGB 8:8:8. stored in the memory continuously and
