29.7.4 RAM palette
The RAM-based palette is a 256 x 16 bit dual-port RAM physically structured as 128 x 32
bits. Two entries can be written into the palette from a single word write access. The Least
Significant Bit (LSB) of the serialized pixel data selects between upper and lower halves of
the palette RAM. The half that is selected depends on the byte ordering mode. In
little-endian mode, setting the LSB selects the upper half, but in big-endian mode, the
lower half of the palette is selected.
