Pulling the mode pin to V
SS
places the dialer in tone mode.
Pulling the mode pin to V
DD
places the dialer in pulse mode (10
ppS, M/B = 2:3).
Floating the mode pin places the dialer in pulse mode (10 ppS, M/B
= 1:2).

Handfree control pins. A low pulse on the
HFI
input pin toggles
the handfree control state.
Status of the handfree control is listed in the following table:

O
This pin is a CMOS N-channel open drain output. The flash key will
cause
DP
to go active in either pulse mode or tone mode. In lock
mode, the
DP
keeps low for 300 mS during off-hook delay time.
The timing diagram is shown as Figure 1(a), 1(b), 1(c), 1(d).

O
In pulse mode, this pin remains in low state at all times.
In tone mode, it will output a dual or single tone. The detailed
timing
diagram for tone mode is shown in Figure 2(a), 2(b), 2(c), 2(d).
