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);
recommended setting
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)
colour peak control active (AD signal is attenuated, if
maximum input level is exceeded, avoids clipping effects on
screen)
colour peak off
AGC active
AGC integration hold (freeze)
automatic gain controlled by MODE5 to MODE0
gain is user programmable via GAI[17:10] and GAI[27:20]
