Color burst reference enable
0 = Color burst reference for AGC disabled (default)
1 = Color burst reference for AGC enabled (not recommended)
TV/VCR mode
00 = Automatic mode determined by the internal detection circuit (default)
01 = Reserved
10 = VCR (nonstandard video) mode
11 = TV (standard video) mode
With automatic detection enabled, unstable or nonstandard syncs on the input video forces the
detector into the VCR mode. This turns off the comb filters and turns on the chrominance trap filter.
Composite peak disable
0 = Composite peak protection enabled (default)
1 = Composite peak protection disabled
Color subcarrier PLL frozen
0 = Color subcarrier PLL increments by the internally generated phase increment (default). GLCO pin
outputs the frequency increment.
1 = Color subcarrier PLL stops operating. GLCO pin outputs the frozen frequency increment.
Luminance peak disable
0 = Luminance peak processing enabled (default)
1 = Luminance peak processing disabled
Power-down mode
0 = Normal operation (default)
1 = Power-down mode. A/Ds are turned off and internal clocks are reduced to minimum.
