Bits 8–0
These nine bits determine color 0 which is displayed when the corresponding OSD pixel code is 00b.
Bits 17–9
These nine bits determine color 1 which is displayed when the corresponding OSD pixel code is 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 color2, which is displayed when the corresponding OSD pixel code is 10b.
Bits 49–41
These nine bits determine color3, which is displayed when the corresponding OSD pixel code is 11b.
Bits 63–50
Reserved and should be set to zero.
