Description
I/O Type
This pin inputs a telephone mute signal.
Input a signal to this pin as follows:
PMUTE Pin
Telephone Mute
0
Telephone mute off
1
Telephone mute on
(0: Low level, 1: High level)
47
PMUTE
Telephone mute
signal input
Mute is on if telephone mute is on.
Input
This pin outputs a mute signal.
This pin outputs a signal as follows, depending on the mute status.
MUTE Pin
Mute
0
Mute on
1
Mute off
(0: Low level, 1: High level)
48

FL LED
Initialization switch
signal input/front
panel detachment
LED lighting signal
output
This is a bi-directional pin that inputs an initialization switch signal
and outputs a signal that lights an LED indicating that the front
panel is detached.
If the front panel is detached, this pin outputs square wave of 1 Hz
with a duty factor of 50%.
This pin functions as an input pin when the initialization switch is
read.
For the initialization switch, refer to “2. KEY MATRIX
CONFIGURATION”.
At all other times, this pin outputs a low level.

Initialization switch
signal input/loading
signal output
This is a bi-directional pin that inputs an initialization switch signal
and outputs a loading signal to the CD player (CDC-01KG).
It outputs a high level when a disc is loaded or ejected.
This pin functions as an input pin when the initialization switch is
read.
For the initialization switch, refer to “2. KEY MATRIX
CONFIGURATION”.
At all other times, this pin outputs a low level.

Initialization switch
signal input/loading
forward signal
output
This is a bi-directional pin that inputs an initialization switch signal
and outputs a loading forward signal to the CD player (CDC-01KG).
It outputs a high level when a disc is loaded or ejected.
This pin functions as an input pin when the initialization switch is
read.
For the initialization switch, refer to “2. KEY MATRIX
CONFIGURATION”.
At all other times, this pin outputs a low level.
