The TV-system is fixed forcibly.
It uses when it is worked in the manual.
Setup Color system detection mode.
Manual / Europeian / South American / Full auto detection.
3-lineComb or BPF is chosen.
0: 3-line-Comb 1: B.P.F
Setup for an output clock frequency.
Select "601：13.5MHz" or "656：27MHz".
Setup for an output bits range (8bit or 10bit).
0：Active 1：OPEN (Because it becomes Hi Impedance,
coexistence with other IC's is possible.）
The control of the power supply for ADC.
0：The power supply of ADC is turned off.
1：Normal (It usually uses by this setup.)
Gain (off, 1/8, 1/4 and 1/2) is set up.
Setup the characteristic of V-enhance gain for non- correlation
Component. Choose it from 4 point
It works with f0 of Noise-canceler as well together.
Pre-Enhance makes it control the part Edgy of Sharpness.
Control the Gain of Sharpness.
1011：-1/4 〜 1111：OFF 〜 0111：8/16
1000, 1001 and 1010 can't be used.
Choose Coring(No response level).
Set the Feed-Back CLAMP.
0: Auto. It becomes a diode clamp when TC90101FG detects a
non-signal. 1：Feed-Back Clamp is active.
Select Internal-Feed-Back or External-Feed-Back.
0: External mode (Pin74, 75 outputs clamp signal).
1: Internal mode (Pin74, 75 : Open). The time-constant for
internal feedback clamp is set via BUS̲FBCLMOD at sub address 32 hex.
Set the Gain of NOISE-CANCEL.
Set the f0 of LTI.
Set the f0 of CTI.
Step is 37[ns] between -296ns〜259ns.
But step is 74[ns] at YCbCr input mode.
It set the Gain of LTI.
It set the Coring(No response level) of LTI.
Use after you confirm a picture.
It set the Gain of CTI.
It set the Coring(No response level) of CTI.
