Function
It is the distinction of D1/D2.
It is effective 32H:D6 when manual set.
Internal control is fixed with D1orD2.
When clamp set internal, it can set time constant.
It set ON/OFF of Peak-AGC Gain.
It is effective when it is ON.
It gives priority to Manual when this bit is ON. Therefore,
it can't get the effect of AGC.
It is effective when 33H(D7).
Gain becomes a fix.
It set start phase of CGP(Output of Terminal-73).
It set width of CGP(Output of Terminal-73).
It set threshold for DET.443.
It is easy to distinguish when a MAX side is chosen.
It is the control of limit-clamp to add under the input signal
at Y input.
Four kinds of switchings are possible.
ON:Always,limitter-clamp to add to Low-level of input is ON.
OFF:Always,limitter-clamp to add to Low-level of input is off.
AUTO1：It is ON in the no-signal and 'When Pedestal-Level
AUTO2：It is ON on no-signal.
It set action of CGP.
AUTO: It is output only when an input signal is set 11(D7 and
D6 on 00H).
Forced on: It is output to all the input.
It is ON, when you want reduce Cross-color and beat.
The Blanking period becomes mute.
It set f0 of Y-Noise-Canceler.
It usually uses on "0".
It set Limitter of Y-Noise-Canceler.
It set Gain of Y-Noise-Canceler.
It set ON/OFF of Y-Noise-Canceler.
It set the condition of CKILL Gain.
When it is set up in +6dB, Level which color disappears to
grows big. It uses "0" when weak electric density.
It set Limitter of C-Noise-Canceler.
It set Gain of C-Noise-Canceler.
It set ON/OFF of C-Noise-Canceler.
deviated greatly.'
