Secondary Input Channel CSC
The CSC must be manually configured for each color space conversion. The CSC on the secondary input channel can be enabled using the
control. This CSC can run at pixel clock frequencies up to 162MHz. The CSC mode on the secondary input channel can be
. The CSC mode is used to define the fixed point position of the CSC coefficients which are located after
in the IO Map for the secondary input channel.
Reference configuration scripts to configure the secondary input channel CSC are provided with the evaluation software.
