CAVR2[6:0] Initial value: 111_1111; Setting range: 000_0000 to 111_1111
Sets increase direction decision average value level of chrominance noise state 2.
Becomes the decision level of the noise level in increasing direction.
CAVR2[6:4] is an integral part and CAVR2[3:0] is a decimal part.
Make sure to set the value larger than CAVR1[5:0].
CAH2 Initial value: 0; Setting range: 0 to 1
Sets decrease direction decision average value level hysteresis coefficient of chrominance noise state 2.
The decision level of the noise level in decreasing direction is set by (CAVR2[6:0]) × (Coefficient)
