Value
Register Name Description
[5] **0***** Low Freq Mode
Sets audio PLL to low frequency mode. Low frequency
mode should only be set for pixel clocks <80 MHz.
[4] ***0**** Low Freq Override
Allows the previous bit to be used to set low frequency
mode rather than the internal auto-detect.
[3] ****0*** Up Conversion Mode 0 = repeat Cr and Cb values.
1 = interpolate Cr and Cb values.
[2] *****0** CrCb Filter Enable Enables the FIR filter for 4:2:2 CrCb output.
[1] ******0* CSC_Enable
Enables the color space converter (CSC). The default
settings for the CSC provide HDTV-to-RGB conversion.
Sets the fixed point position of the CSC coefficients,
including the A4, B4, C4 offsets.
0x35 Read/Write [6:5] *01* **** CSC_Mode 00 = ±1.0, −4096 to +4095.
01 = ±2.0, −8192 to +8190.
1× = ±4.0, −16384 to +16380.
