PIN NAME
PIN No.
SYMBOL
Beep output pin when momentary key pressed. A 2.25
kHz and 50 % duty square wave is output for approx.
40 ms. This time is equal to the premuting time.
When a momentary key is pressed and the state of the
LCD panel display or output port is changed (valid key)
and at the end of 5 seconds hold during preset memory
scan and scan operations, a beep is output.
To disable the beep, float (leave open) this pin.
The beep output is also used at SK alarm at DK standby.
LCD panel segment signal output (pins 28 to 55) and
key matrix key source signal output (pins 40 to 55)
pins.
56-dot display is performed at the LCD panel by matrix
with the COM
1
pin (pin 56) and COM
2
pin (pin 57).
Since LCD

0
/KS
0
(pin 55) share the
key source signal and LCD segment signal, to use them
as key source signals, a reverse current prevention
diode is necessary. For the connection method, see
1.3
“Key Matrix Connection”
and
6 “Application Circuits”.
Common signal output to LCD panel.
56-dot display is performed at the LCD panel by matrix
with LCD

(pin 55).
Key matrix key return signal input pin.
Since the key source signal output is shared with the
LCD segment signal, do not connect a pull-down resis-
tor to this pin.
