Attribute Table and Enhanced Features
Each display character and SL in the Display Page RAM will have a 4-bit Attribute Table entry associated with it. The user should
note that two-color display characters and four-color display characters use two different Attribute Tables, effectively providing 16
attributes for two-color display characters and 16 attributes for four-color display characters.
For two-color characters, the attribute contains the code for the 9-bit foreground color (Color 1), the code for the 9-bit background
color (Color 0), and the character’s enhanced features (Button Box, Blinking, Heavy Box, Shadowing, Bordering, etc.).
For four-color characters, the attribute contains the code for the 9-bit Color 0, the code for the 9-bit Color 1, the code for the 9-bit
Color 2, the code for the 9-bit Color 3, and the character’s enhanced features (Button Box, Blinking, Heavy Box, Shadowing,
Bordering, etc.).

These nine bits determine the background color (color1), which is displayed when the
corresponding OSD pixel is a 0.
These nine bits determine the foreground color (color2), which is displayed when the
corresponding OSD pixel is a 1.
These are the enhanced feature (EF) bits, which determine which feature is applied to the
displayed character. The features and their corresponding codes are shown in
Table 24
