4 bpp color
When the SED1355 is configured for 4 bpp color mode the first 16 entries in the LUT are used.
Each byte in the display buffer contains two adjacent pixels. The upper and lower nibbles of the byte
are used as indices into the LUT.
The following table shows LUT values that will simulate those of a VGA operating in 16 color
mode.
