DESCRIPTION
0 = copy generation data output is disabled; default state after reset
1 = copy generation data output is enabled
These 3 bits are reserved; each must be set to logic 0.
Remaining bits of copy generation code.

DESCRIPTION
These 3 bits are reserved; each must be set to logic 0.
Gain luminance of RGB (CR, Y and CB) output, ranging from (1 − 16⁄32) to (1 + 15⁄32).
Suggested nominal value = −6 (11010b), depending on external application.
