COLOR CONTROLS AND RGB MATRIX
HD Y Level, HD Cr Level, HD Cb Level
[Subaddresses 0x16 to 0x18]
Three 8-bit registers at Addresses 0x16, 0x17, and 0x18 are used
to program the output color of the internal HD test pattern
generator, be it the lines of the cross hatch pattern or the
uniform field test pattern. They are not functional as color
controls for external pixel data input. For this purpose, the RGB
matrix is used.
The values for Y and the color difference signals used to obtain
white, black, and saturated primary and complementary colors
conform to the ITU-R BT.601-4 standard.
Table 29 shows sample color values that can be programmed
into the color registers when the output standard selection is
set to EIA 770.2.

RGB Matrix
[Subaddresses 0x03 to 0x09]
The internal RGB matrix automatically performs all YCrCb to
RGB scaling according to the input standard programmed in
the device as selected by input mode Register 0x01 [6:4]. Table 30
shows the options available in this matrix.
Note that it is not possible to do a color space conversion from
RGB-in to YPrPb-out. Also, it is not possible to input SD RGB.

Manual RGB Matrix Adjust Feature
Normally, there is no need to enable this feature in Register 0x02,
Bit 3, because the RGB matrix automatically performs color
space conversion depending on the input mode chosen (SD/PS,
HD) and the polarity of RGB/YPrPb output in Register 0x02,
Bit 5 (see Table 30). For this reason, the manual RGB matrix
adjust feature is disabled by default. However, For HDTV
YCrCb-to-RGB conversion, the RGB matrix must be enabled to
invoke the correct coefficients for this color space. The
coefficients do not need to be adjusted.
The manual RGB matrix adjust feature provides custom
coefficient manipulation and is used in PS and HD modes only.
When the manual RGB matrix adjust feature is enabled, the
default values in Registers 0x05 to 0x09 are correct for HDTV
color space only. The color components are converted
according to the 1080i and 720p standards (SMPTE 274M,
SMPTE 296M)
