Selecting Auto or Manual CSC Conversion Mode

The ADV7604 CSC provides two modes for the CSC configuration: automatic CSC mode and
manual CSC mode.
In automatic CSC mode, the user is required to program the input color space and the output color
space for the correct operation of the CSC matrix. Manual CSC mode allows the user to program all
the color space conversion by manually programming CSC coefficients (refer to Section 8.4.5).

The selection of the CSC is automated in the ADV7604. Automatic or manual CSC mode can be
selected by setting the CSC_COEFF_SEL[3:0] bits. When CSC_COEFF_SEL[3:0] is set to 4b1111,
the CSC mode is automatically selected, based on the input color space and output color space
required and set through the following registers:
•
INP_COLOR_SPACE[3:0]
•
RGB_OUT
•
ALT_GAMMA
