Fast lock mode:
0 = Normal operation (default)
1 = Fast lock mode. Locks within three fields if stable input signal and forced video standard.
Color burst reference enable:
0 = Color burst reference for AGC disabled (default)
1 = Color burst reference for AGC enabled
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 chroma trap filter.
White peak disable:
0 = White peak protection enabled (default)
1 = White 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.
Luma peak disable
0 = Luma peak processing enabled (default)
1 = Luma 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.
