Two entries can be written into the palette from a single word write access. The LeastSignificant Bit (LSB) of the serialized pixel data selects between upper and lower halves ofthe palette RAM. The half that is selected depends on the byte ordering mode. Inlittle-endian mode, setting the LSB selects the upper half, but in big-endian mode, thelower half of the palette is selected.Table 631.
