These nine bits determine color 0 which is displayed when the corresponding OSD pixel code is
00b.
These nine bits determine color 1 which is displayed when the corresponding OSD pixel code is
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 30. Enhanced
Feature Descriptions.
Reserved and should be set to zero.
These nine bits determine color2, which is displayed when the corresponding OSD pixel code is
10b.
These nine bits determine color3, which is displayed when the corresponding OSD pixel code is
11b.
