Description
I/O Type
This pin inputs a vibration detection signal from the RF amplifier of
the CD player (CDC-01KG).
Pull up this pin externally.
Input a signal to this pin as follows:
DET Pin

BEEP
Beep output
Outputs a beep.
This pin outputs a square wave of 1.5 kHz with a duty factor of 50%
as a beep in the following cases:
(1) When a momentary key is pressed and a key operation is
performed.
(2) When the received preset memory is changed by the preset
memory scan operation of the radio
At all other times, this pin outputs a high level.
However, in the standby mode, it goes into a high-impedance state.

Hardware diagnosis
signal input
This pin inputs a hardware diagnosis signal.
If a high level is input to this pin in the power-on status, “!!!” is
displayed.

61
CDP MOD
CD mode signal
output
This pin outputs a CD mode signal.
This pin outputs a high level in the CD mode.
In other modes, it outputs a low level.
For the output timing of the CD mode signal, refer to “12. MUTE
OUTPUT TIMING CHART”.

TUN MOD
Radio mode signal
output
This pin outputs a radio mode signal.
This pin outputs a high level in the radio mode.
In other modes, it outputs a low level.
For the output timing of the radio mode signal, refer to “12. MUTE
OUTPUT TIMING CHART”.

LCD SIO
LCD driver data
signal I/O
This pin inputs or outputs a serial data signal to or from an LCD
driver IC (
μ
PD16431A).
Connect this pin to the DATA pin (pin 8) of the LCD driver IC
(
μ
PD16431A) and externally pull up the connection line between
the pins.
Communication with the LCD driver IC (
μ
PD16431A) is carried out
in the 2-wire serial mode.
This pin reads data at the rising edge of the LCD CLK pin and
outputs data at the falling edge.
It outputs a high level in the standby mode.

LCD CLK
LCD driver clock
signal output
This pin outputs a serial clock signal to the LCD driver IC
(
μ
PD16431A).
Connect this pin to the SCK pin (pin 7) of the LCD driver IC
(
μ
PD16431A) and externally pull up the connection line between
the pins.
Communication with the LCD driver IC (
μ
PD16431A) is carried out
in the 2-wire serial mode.
This pin outputs a high level in the standby mode.
