The keyboard inputs may be used with either a standard 5 × 5
I keyboard or an inexpensive single contact (Form A) keyborad.
Electronic input from a µC can also be used.
A valid key in is defined as a single row being connected to a single
column.
7, 8 I, O A built-in inverter provides oscillation with an inexpensive 3.579545
MHz crystal or ceramic resonator.
9 O The T/P MUTE is a conventional CMOS N-channel open drain output.
The output transistor is switched on during dialing sequence and flash
break time. Otherwise, it is switched off.
13 I Pulling mode pin to VSS places the dialer in tone mode.
Pulling mode pin to VDD places the dialer in pulse mode with M/B ratio
40:60
(20 ppS only for W91433N and 10 ppS for the others, M/B = 40:60).
Floating mode pin places the dialer in pulse mode with M/B ratio 33:67
(20 ppS only for W91433N and 10 ppS for the others).
