VCC-1.0
The device operates in AM mode when a current of
over 200
μ
A flows from pin. 12.

Pilot detector low-
pass filter (Forced
mono) (VCO stop)
VCC-1.0
The device is forced to monaural when a current of
over 50
μ
A flows from this pin.
The VCO is stopped when a current of over 200
μ
A
flows from this pin.
The limit values for the resistor are the same as
those for pin 11.
