4: LOOK-UP TABLE (LUT)
2-14
4 bpp gray shade
When the S1D13705 is configured for 4 bpp gray shade mode the displayed colors are selected from
the green values of the first sixteen entries of the Look-Up Table. Each of the sixteen entries can be
set to any of the sixteen possible intensity levels.
Each byte in the display buffer contains two adjacent pixels. If a nibble pattern is “0000” then the
green intensity of LUT index 0 is displayed. A nibble value of “0001” results in the green intensity
in LUT index 1 being displayed. The pattern continues to the nibble pattern of “1111” which results
in the sixteenth intensity of Look-Up Table being displayed.
The following table shows the example values for 4 bit-per-pixel display mode.
