10-CHANNEL AUTO SCAN CORDLESS PHONE CONTROLLER WITH LCD DISPLAY
I/O

O
H
In-use indicator.
(P.P.)
High output when the handset or the base unit is being used.
I
L
Carrier detect input.
This pin senses the RF carrier of the air-link. It functions when the /
TXPWR=low which implies that air-link ready between handset and base
unit. If it detects no RF carrier (/CDI input high) for more than 20 seconds,
the base unit returns to standby automatically. In normal air-linked
condition, the external RF carrier detection circuit must set the /CDI pin
to low.
O
H
DTMF signal output.
In base unit dialing, the DTMF signal is generated as long as the key is
pressed. For handset dialing and speed dialing, the DTMF signal complies
with minimum tone duration (100ms) and minimum inter-tone pause (100ms).
O
L
To profect IC. Watck dog timer.
(O.D)
Connect to Reset pin to prevent IC malfunction. When system error, this
pin will output :LOW" for system reset..

Hook switch detect input pin.
(O.D)
Input low off-Hook, Input high ON-Hook.

Common pins for LCD driver.
Segnment pins for LCD driver.
Telephone line connection output. Open drain structure.
For loop connection. It also outputs pulse dialing or flash (line break)
signals.
DTMF and pulse dialing signal mute output.
The XMUTE pin executes the transmission mute of the DTMF and pulse
signal dialing out.
Handset in-use audio signal switch output.
To turn on the audio path for handset line where in-use.
Base speakerphone audio signal switch output.
To turn on the audio path for base unit making or receiving a call.
Intercom audio signal switch output.
To turn on the audio path for intercom between handset and base unit.
Line hold output for music control.
The HDO outputs high when line is hold. It may also be used to control
a music generator while line holding.
Speaker amplifier power control output.
Output low to enable the power for speaker amplifier.
Microphone amplifier power control output.
Output low to enable the power for microphone amplifier. It is also used
to execute microphone mute function.
Hold release input pin, the internal debounce time is 48 ms. When this pin
detects "low" will release hold mode.
Ringing signal envelope detection input.
It detects the envelope of of incoming ring whether a ring is present or not.
In normal no ringing condition, a high level signal input to this pin. If line
ringing happens, input low for ring-on and input high for ring-off.
