34.4.15 Color Space Conversion Coefficient Register 1
This register contains color space conversion coefficients in two's compliment notation.
The Coeffient 1 register contains coeffients used in the color space conversion algorithm.
C1 is the coeffient that is used to multiply the chroma (Cr/V) component of the data for the
red component. C4 is the coeffient that is used to multiply the chroma (Cb/U) component
of the data for the blue component. Both values should be coded as a two's compliment
fixed point number with 8 bits right of the decimal.

RSVD1
Set to 1 when performing YCbCr conversion to RGB. Set to 0 when converting YUV to RGB data. This bit
changes the behavior of the scaler when performing U/V scaling.
Reserved, always set to zero.
Two's compliment Y multiplier coefficient. YUV=0x100 (1.000) YCbCr=0x12A (1.164)
Two's compliment phase offset implicit for CbCr data. Generally used for YCbCr to RGB conversion.
YCbCr=0x180, YUV=0x000 (typically -128 or 0x180 to indicate normalized -0.5 to 0.5 range)
Two's compliment amplitude offset implicit in the Y data. For YUV, this is typically 0 and for YCbCr, this is
typically -16 (0x1F0)
