ACE = Adaptive comb filter enable.
CE = Comb filter enable.
CM[2:0] = Comb filter mode.
LE = Luminance filter select.
CF = Chrominance filter select.
LF = Luminance filter select.
X = No change
Chrominance control register register 1A, bit 3
Chrominance control register register 1A, bit 2
Chrominance control register register 1A, bits 7-5.
Luminance processing control 2 register 08, bit 6
Chrominance control 2 register 1B, bits 1 and 0.
Luminance control 3 register 0E, bits 1 and 0.
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 stops incrementing and is frozen to nominal. GLCO terminal outputs zero.
Power-down mode:
0 = Normal operation (default)
1 = Power-down mode. A/Ds are turned off and internal clocks are reduced to minimum.
