DD
Positive Voltage Supply
This is the supply pin for the circuit.
A
This is the analogue ground for the amplifiers.
S
This is the input for side tone cancellation.
C
For complex impedance a capacitor should be connected to
M
PDM output of the melody generator for tone ringing with internal open-drain transistor.
Hi-Z when not active.
L
Select pin for line loss compensation (see also Figure 6 and Figure 7).
LLC = A
H
This is an I/O that is pulled high by the hook switch when off-hook and an open drain pulls it low
during break periods of pulse dialing and flash.
OSC
Pin for ceramic resonator (3.58 MHz).
