If all four bits of the lower nibble are set to logic 1 (that is, no amplitude reference selected), then the front-end analog and digital gains are
automatically set to nominal values.
If all four bits of the upper nibble are set to logic 1 (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%.
