c VOX output pin. Open collector output.
c Chip enable input pin.
c Data input pin.
c Clock input pin.
c Reset pin. Power-on reset.
c Pad control pin. By connecting this pin to
GND or to S. V_CC (pin 63) through a resistor,
it is possible to use the line current for gain
control and to control the operating current
for BN switching.
