Figure 2.8 Configuration of the Look-up Tables
The pixel data in the display memory is used as an index to the look-up tables, so that luminance data is generated
based on the values in the entries indicated by the pixel data, before being output to the LCD panel.
The LCD controller can control reversal of the display. This control is exercised on the output of the look-up
tables.
