Note: The SDRAM configuration register must be programmed before enabling features that require the SDRAM. Failure to do so will  
result in incorrect operation of the memory controller  
3DYC:  
0 = Disable; the 2D adaptive 5-line comb filter is enabled (default)  
1 = Enable  
3DYC enhances 2D Y/C separation by utilizing temporal-based, or frame-based information. 3DYC requires the use of the frame buffer  
memory and can be used simultaneously with 3DNR and TBC.  
TBC:  
00 = Disable (default)  
01 = On  
10 = Automatic selection  
11 = Automatic selection  
Line-based time correction corrects for horizontal phase errors encountered during video decoding up to ±80 pixels of error. TBC can  
be used simultaneously with 3DYC and 3DNR. TBC does not require external memory.  
Chrominance adaptive comb enable:  
0 = Enable (default)  
1 = Disable  
This bit is effective on composite video only.  
3DNR:  
0 = Disable (default)  
1 = Enable  
Frame recursive noise reduction minimizes the amount of noise in interlaced CVBS, S-Video, or component inputs. 3DNR requires the  
use of the frame buffer memory and can be used simultaneously with 3DYC and TBC.  
Note: Noise reduction can not be used on progressive inputs.  
Automatic color gain control (ACGC) [1:0]:  
00 = ACGC enabled (default)  
01 = Reserved  
10 = ACGC disabled, ACGC set to the nominal value  
11 = ACGC frozen to the previously set value
