Luma peak A: Use of the luma peak as a video amplitude reference for the back-end feed-forward type AGC algorithm  
0 = Enabled (default)  
1 = Disabled  
Color burst A: Use of the color burst amplitude as a video amplitude reference for the back-end  
NOTE: Not available for SECAM, component and B/W video sources.  
0 = Enabled (default)  
1 = Disabled  
Sync height A: Use of the sync height as a video amplitude reference for the back-end feed-forward type AGC algorithm  
0 = Enabled (default)  
1 = Disabled  
Luma peak B: Use of the luma peak as a video amplitude reference for front-end feedback type AGC algorithm  
0 = Enabled (default)  
1 = Disabled  
Composite peak: Use of the composite peak as a video amplitude reference for front-end feedback type AGC algorithm  
NOTE: Required for CVBS video sources  
0 = Enabled (default)  
1 = Disabled  
Color burst B: Use of the color burst amplitude as a video amplitude reference for front-end feedback type AGC algorithm  
NOTE: Not available for SECAM, component and B/W video sources  
0 = Enabled (default)  
1 = Disabled  
Sync height B: Use of the sync-height as a video amplitude reference for front-end feedback type AGC algorithm  
0 = Enabled (default)  
1 = Disabled  
NOTE: If all 4 bits of the lower nibble are set to 1111b (that is, no amplitude reference selected), then the front-end analog and digital  
gains are automatically set to nominal values.  
If all 4 bits of the upper nibble are set to 1111b (that is, no amplitude reference selected), then the back-end gain is set automatically to  
unity. If the input sync height is greater than 100% and the AGC-adjusted output video amplitude becomes less than 100%, then the  
back-end scale factor attempts to increase the contrast in the back-end to restore the video amplitude to 100%.
