FUNCTION NAME
This is a 2's complement number controlling the target
code of the Red ADC output when ABLC is enabled.
In RGB mode, the Red ADC output will be servoed to
0x00 + the number in this register (-0x00 to +0x7F).
In YPbPr mode, the Red ADC output will be servoed
to 0x80 + the number in this register (-0x80 to +0x7F).
Note: This register does NOT disable the digital offset
adder. Both functions can be used simultaneously.
This is a 2's complement number controlling the target
code of the Green ADC output when ABLC is enabled.
In RGB and YPbPr modes, the Green ADC output will
be servoed to 0x00 + the number in this register
(-0x00 to +0x7F).
Note: This register does NOT disable the digital offset
adder. Both functions can be used simultaneously.
This is a 2's complement number controlling the target
code of the Blue ADC output when ABLC is enabled.
In RGB mode, the Blue ADC output will be servoed to
0x00 + the number in this register (-0x00 to +0x7F).
In YPbPr mode, the Blue ADC output will be servoed
to 0x80 + the number in this register (-0x80 to +0x7F).
Note: This register does NOT disable the digital offset
adder. Both functions can be used simultaneously.
