8.5.6 Programming the Color Palettes

The Palette attributes are coded inside the two

Palettes (Basic background and foreground, and

Extended background and foreground); they are

therefore accessible in all modes, parallel as well

as serial.

A palette contains 16 colors each defined with a

16-bit word. For each color, you can define the red

level (1 of 8 values), the green level (1 value

among 8), the blue level (1 value among 8), and

the translucency level (1 value among 8).

The color palettes also bring improvements in un-

derline control to allow for “Windows-like” buttons.

Once programmed, color palettes can be changed

in real-time when the OSD is running, that is to say

when the software is filling one row buffer while the

other one is displayed (but take care that the row

currently displayed may be using some of the

colors which you want to modify).
