33.5.5 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.
