I
The keyboard inputs may be used with either the
standard 5
×
4 keyboard or the inexpensive single
contact (Form A) keyboard. Electronic input from a
μ
C can also be used.
A valid key-in is defined as a single row being
connected to a single column.
XT, XT

I, O
A built-in inverter provides oscillation with an
inexpensive 3.579545 MHz crystal or ceramic
resonator.
T/P
MUTE
9
9
O
The T/P MUTE is a conventional CMOS N-channel
open drain output.
The output transistor is switched on during dialing
sequence, one-key redial break, and flash break
time. Otherwise, it is switched off.
MODE
13
15
I
Pulling mode pin to V
SS
places the dialer in tone
mode.
Pulling mode pin to V
DD
places the dialer in pulse
mode. (10 ppS; 20 ppS for W91331N/W91331AN,
M/B = 40:60)
Floating mode pin places the dialer in pulse mode.
(10 ppS; 20 ppS for W91331N/W91331AN, M/B =
33.3:66.7).
HKS

I
Hook switch input.
HKS = V
DD
: On-hook state. Chip in sleeping mode,
no operation.
HKS = V
SS
: Off-hook state. Chip enabled for normal
operation.
HKS pin is pulled to V
DD
by internal resistor.
DP

O
N-channel open drain dialing pulse output.
Flash key will cause DP to be active in either tone
mode or pulse mode.
The timing diagram for pulse mode is shown in
Figure 1(a, b, c, d).
