Digital Color Clamp Offset. Holds upper 4 bits of the digital offset value which is added to the raw data from the ADC before entering the core.
Digital Clamp Freeze Enable. Allows the user to freeze the digital clamp loop at any point in time.
Digital Clamp Timing. Determines the time constant of the digital clamping circuitry.
Digital Color Clamp Mode. Sets the mode of operation for the digital clamp circuitry. Offset correction via DCCO for C only.
Offset Correction via DCCO for C only.
Y Shaping Filter Mode. Allows the user to select a wide range of low-pass and notch filters.
C Shaping Filter Mode. Allows the selection from a range of low-pass chrominance filters. Auto = filter selected based on scaling factor.
