Description
Allows the previous bit to be used to set low
frequency mode rather than the internal auto-
detect.
0 = repeat Cr and Cb values.
1 = interpolate Cr and Cb values.
Enables the FIR filter for 4:2:2 CrCb output.
Enables the color space converter (CSC). The
default settings for the CSC provide HDT-to-RGB
conversion.
Sets the fixed-point position of the CSC
coefficients, including the A4, B4, and C4 offsets.
00 = ±1.0, −4096 to 4095.
01 = ±2.0, −8192 to 8190.
1× = ±4.0, −16384 to 16380.
