8.3 COLOR SPACE CONVERSION MATRIX

The ADV7850 provides any-to-any color space conversion support. It supports formats such as RGB, YUV, and YCbCr. The Color Space
Converter (CSC) is designed to run at speeds of up to 170 MHz.
The CSC is in the CP block (CP
CP CSC is the main color space converter. The CPP block also has an automatic non programmable CSC. The ADV7850 will
automatically configure the fixed CSC for certain modes, depending on the input and output formats and the use of the color control
feature.
The configuration of the color space conversion using the CP CSC block and a description of the adjustable controls is provided in
76.

man_cp_csc_en, Addr 44 (CP), Address 0x69[4]
This control is used to manually enable the CP CSC. By default, the CP CSC is automatically enabled in the case where either a color
space conversion or video adjustment (hue, saturation, contrast, or brightness) is determined to be required due to other I2C settings. If
man_cp_csc_en is set to 1, the CP CSC is forced into the enabled state.
