Peak
Color
Sync
This register disables the back-end AGC when the front-end AGC uses specific amplitude references (sync-height, color burst, or
composite peak) to decrement the front-end gain. For example, writing 0x09 to this register disables the back
end AGC when the front-end
AGC uses the sync-height to decrement the front-end gain.
Peak:
Disables back-end AGC when the front-end AGC uses the composite peak as an amplitude reference.
0 = Disabled (default)
1 = Enabled
Color:
Disables back-end AGC when the front-end AGC uses the color burst as an amplitude reference.
0 = Disabled (default)
1 = Enabled
Sync:
Disables back-end AGC when the front-end AGC uses the sync height as an amplitude reference.
0 = Disabled (default)
1 = Enabled
