COLOR SPACE CONVERSION
The default power up values for the color space converter
coefficients (R0x35 through R0x4C) are set for ATSC RGB to
YCbCr conversion. They are completely programmable for
other conversions.
0x34—Bit[1] Color Space Converter Enable
This bit enables the color space converter. 0 = disable color
space converter. 1 = enable color space converter. The power-up
default setting is 0.
0x35—Bits[6:5] Color Space Converter Mode
These two bits set the fixed-point position of the CSC
coefficients, including the A4, B4, and C4 offsets.

0x35—Bits[4:0] Color Space Conversion Coefficient A1
MSBs
These 5 bits form the 5 MSBs of the Color Space Conversion
Coefficient A1. This combined with the 8 LSBs of the following
register form a 13-bit, twos complement coefficient which is
user programmable. The equation takes the form of:
The default value for the 13-bit A1 coefficient is 0x0C52.

LSBs
See the Register 0x35 section.
0x37—Bits[4:0] CSC A2 MSBs
These five bits form the 5 MSBs of the Color Space Conversion
Coefficient A2. Combined with the 8 LSBs of the following
register, they form a 13-bit, twos complement coefficient that is
user programmable. The equation takes the form of:
The default value for the 13-bit A2 coefficient is 0x0800.
