RAM palette

The RAM-based palette is a 256 x 16-bit dual-port RAM physically structured as

128 x 32 bit. This allows two entries to be written into the palette from a single word write

access. The least significant bit of the serialized pixel data is used to select between upper

and lower halves of the palette RAM. Which half is selected depends on the bytes ordering

mode. In little-endian mode, the LSB being set selects the upper half, but in big-endian, the

lower half of the palette is selected. WinCE byte ordering is little-endian, so the former case

applies.

Pixel data values can be written and verified through the AMBA AHB slave interface.

For information on the numbers of colors supported, refer to Section 24.2: Main features.
