FUNCTION
The keyboard inputs may be used with either the standard 5
×

keyboard, an inexpensive single contact (form A) keyboard or
electronic input.
A valid key entry is defined by a single row being connected to a
single column.
A built-in inverter provides oscillation with an inexpensive
3.579545 MHz crystal or ceramic resonater.
The oscillator ceases when a keypad input is not sensed after the
chip is enabled and dialing is finished. The crystal frequency
deviation is
±
0.02%.

O
The T/P
MUTE
is a conventional CMOS N-channel open drain
output.
The output transistor is switched on low level during the dialing
sequence (both pulse and tone mode), one-key redial break and
flash break. Otherwise, it is switched off.
The H/P MUTE is a conventional CMOS inverter output, During
pulse dialing, one-key redial break, flash break and hold functions,
this pin will output an active high.
It remains in a low state at all other times.

LOCK
(W91561DLNF,

only)
I
The LOCK pin is used to prevent "0" or "9" dialing under PABX
system long distance call control. When the first key input after
reset is "0" or "9", all the key inputs, including the "0" or "9" key,
become invalid, and the chip generates no output.
The telephone is reinitialized by a reset.
The following table describes the functions of the LOCK pin:
