Table 4-4: Suggested LUT Values to Simulate VGA Default 16 Color Palette
4 bpp color
When the S1D13505 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.
