S1D13705F00A PROGRAMMING NOTES
AND EXAMPLES (X27A-G-002-01)
2 bpp gray shade
When the S1D13705 is configured for 2 bpp gray shade, the displayed colors are selected from the
first four green entries in the Look-Up Table. The remaining entries of the LUT are unused. Each of
the four entries can be set to any of the sixteen possible colors.
Each byte in the display buffer contains four adjacent pixels. If a bit combination has a value of “00”
then the intensity in the green LUT index 0 is displayed. A bit value of “01” results in the intensity
represented by the green in LUT index 1 being displayed. Likewise the bit combination of “10”
displays from the third LUT entry and “11” displays a from the fourth LUT entry.
The following table shows the example values for 2 bit-per-pixel display mode.
