Programming Notes and Examples
Issue Date: 01/02/12
4 Bpp Color
When the S1D13704 is configured for 4 bit-per-pixel operation all sixteen Look-Up Table
entries 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 simulate those of a VGA operating in 16 color
mode.
