normal clamping if decoder is in unlocked state
reference select if decoder is in unlocked state
short vertical blanking (AGC disabled during equalization
and serration pulses)
long vertical blanking (AGC disabled from start of
pre-equalization pulses until start of active video (line 22 for
60 Hz, line 24 for 50 Hz)
white peak control active
white peak control off
AGC active
AGC integration hold (freeze)
automatic gain controlled by MODE3 to MODE0
gain is user programmable via GAI[17:10] and GAI[27:20]
