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)
color peak control active (AD signal is attenuated, if
maximum input level is exceeded, avoids clipping
effects on screen)
color 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]
