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.

places the
dialer in tone mode.
Pulling mode pin to V
DD
places the
dialer in pulse mode. (10 ppS; 20 ppS
for W91321N/321AN M/B = 40:60)
Floating mode pin places the dialer in
pulse mode. (10 ppS; 20 ppS for
W91321N/321AN M/B = 33.3:66.7)
