/MUTE

Transmission and Receiver mute output.
/MUTE outputs a low signal to disable the microphone and speaker or
send a low signal to compressor for transmission muting.
RF transmitter power control output.
The RF transmitter power can be controlled by this pin. It outputs high
signal to RF transmitter in stand-by mode and sends low signal in in-use
mode.
RF receiver power control output.
The RF receiver power is controlled by this pin at a ratio of 1:2 (min.
1 sec ON) when the handset is in standby mode and at receive off time
system run at slow mode by 32768 crystal run at very low power
consumption.
This function is called “power saving”. /RXPWR goes low in in-use
mode and low/high (ON/OFF) ratio of 1:2 in standby mode.
Talk mode indicator.
It sinks current to drive an LED directly in talk mode and toggles to flash
LED where in line hold mode.
Keypad backlight indicator.
For the power saving consideration, the /BCKLED will only be kept
low for 8 seconds after each dialing key pressed. It also toggles to
flash the LED during incoming ring or paging from base unit, selected
by R option.
Battery low indicator.
It indicates the low battery condition. It sinks current to drive an LED
directly when /BATL pin is low and in in-use mode.
Battery low detection input.
A low input to this pin when battery is low. This pin only functions when
in in-use mode. (/TXPWR=low).
Carrier sense input.
It works when /TXPWR=low and /RXPWR=low to sense the RF carrier.
In normal air-linked condition, the external RF carrier detection circuit
must has a low level signal input to /CDI pin. When there is no RF carrier
detected (/CDI=high), beep tone from /BEEP pin will be activated
every 5 seconds. If the carrier is lost for more than 20 seconds, the
handset will return to standby mode automatically.
High input to this pin disable the backlight during ringing and paging in
order to save power from flashing backlight.
No connection.
Oscillator Input/Output.
A 4MHz crystal is required, two 10pF capacitors should be connected
from XIN and XOUT to ground respectively.
System reset input.
Low input to this pin resets the controller. The system reset can be done
when the first time power up or putting the handset on the charge cradle.
To reset the controller, a minimum of 10ms low pulse is required. If the
handset battery is to be changed, a low signal should be detected PWDN
