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 input video will force the device into VCR mode.
This turns off the luminance and chrominance comb filters and turns on the chroma trap filter.

ACE = Adaptive comb filter enable.
Chrominance control register 1A, bit 3
CE = Chrominance comb filter enable.
Chrominance control register 1A, bit 2
CM[2:0] = Chrominance comb filter mode.
Chrominance control register 1A, bit 7-5.
LE = Luminance filter select.
Luminance processing control #2 Register 08, bit 6
CF = Chrominance filter select.
Chrominance control #2 register 1B, bit 1 and 0.
LF = Luminance filter select.
Luminance control #3 register 0E, bit 1 and 0.
X = No change
Color subcarrier DTO frozen:
0 = Color subcarrier DTO increments by the internally-generated phase increment. (default)
GLCO terminal outputs the phase increment.
1 = Color subcarrier DTO forced to nominal value
Powerdown mode:
0 = Normal operation (default)
1 = Power-down mode. A/Ds are turned off and internal clocks are reduced to minimum.
