Composite video/S selector.

The detection results are written to the status

register.

S signal at 3.5V or less.

Composite video signal at 3.5V or more.

This pin is pulled up to 5V by a 100kΩ

resistor, so the composite video signalis

selected when open.

Detects the S2-compatible DC superimposed

onto the C signal.

4:3 video signal at 1.3V or less.

4:3 letter-box signal at 1.3V or moreto2.5V

or less.

16:9 picture squeezed signal at 2.5V or more.

This pin is pulled down to GND by a 100kΩ

resistor, so the 4:3 video signal is selected

when open.
