These nine bits determine the color1 which is displayed when the corresponding OSD pixel code is 00b.
These nine bits determine the color2 which is displayed when the corresponding OSD pixel code is a 01b.
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 14. Attribute Tables and Corresponding
Addresses.
