Bits 8–0
These nine bits determine the color0 which is displayed when the corresponding OSD pixel code is 00b.
Bits 17–9
These nine bits determine the color1 which is displayed when the corresponding OSD pixel code is a 01b.
Bits 21–18
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.
Bits 31–22
Reserved and should be set to zero.
Bits 40–32
These nine bits determine the color2 which is displayed when the corresponding OSD pixel code is a 10b.
Bits 49–41
These nine bits determine the color3 which is displayed when the corresponding OSD pixel code is an 11b.
Bits 63–50
Reserved and should be set to zero.
