PIN NAME
I / O pin used to control SECAM
demodulator IC.
If 250 µA or more flows from this pin,
SECAM is determined.
Outputs B-Y (U) signal or Cb signal.
Incorporates LPF to reject carrier.
Outputs R-Y (V) signal or Cr signal.
Incorporates LPF to reject carrier.
Pulling up the pin with 10 kΩ
monitors CHROMA signal after ACC
and TOF circuits (before demo
input).
