Function
A valid key entry is defined by a single row being
connected to a single column
Oscillation I/O
The T/P MUTE is a conventional CMOS N-channel
open drain output. When dialing and flash, the output is
and will turn down the talking network.
Dialing mode selection.. When pin is connected
to VSS , it is double tone multi-frequency mode
when it is connected to VDD , it is pulse mode
(10ppS).
The pin is the hook switch input
HKS =1, on HOOK state, chip in sleeping mode,
no operation.
HKS =0, on HOOK state enable chip on normal
operation..
Break/make ratio, pin selection.
B/M=1, ratio is 60/40;
B/M=0, ratio is 66/33.
Power and power ground input
Inverter output. Dialing under double tone
mode, pin is high voltage if dialing under
pulse mode, the pin is low voltage.
Hands-free control details can be seen in
table2.
Key tone signal output. The frequency
is1.2KHz.
Once the pin is locked, dialing starting with
"0" or "9" and all the key input afterwards
will become invalid. It will recover the
original state after on hook..
