Pin Name
Pin No.
Function
Modulation level input pin.
When starting AF operation with DEV.SEL switch of initial
setting diode = 1 (shorted with diode), this pin is used to
detect weakly modulated part (mute part), as follows:
DEV.LEVEL
0
1
(0: low level, 1: high level)
Description
Mute
Sound
Broadcasting station detection signal input pin.
Input pin that detects SK signal of VF broadcasting station.
It is used as auto tuning stop signal. If low level is input
to this pin within about 500 ms after broadcasting station
has been detected, it is judged that a traffic information
station was detected, and auto tuning is stopped.
Pull up this pin when ARI is not used.
Input pin that detects DK signal of VF broadcasting station.
It is judged that traffic information is being broadcast and
standby mode is set if both SK (pin 76) and DK pin go low
in standby mode.
If DK pin goes high, standby mode is set again.
Pull up this pin when ARI is not used.
This pin indicates whether front panel is attached or de-
tached. When this pin goes high, it indicates that front
panel is detached.
Connect this pin to GND via pull-down resistor.
