Analog Speaker Out/Interrupt.
Provides an analog output signal for driving a call progress speaker or a hardware
interrupt for multiple sources of interrupts.
Ground.
Connects to the system digital ground.
Analog Supply Voltage.
Provides the analog supply voltage for the Si3056.
Mode Select 0.
The first of two mode select pins that selects the operation of the serial port/DSP inter-
face.
Output signal that indicates the status of a ring signal. Produces an active low rectified
version of the ring signal. When daisy chain is enabled, this signal becomes a delayed
frame sync to drive a slave device. It is also the second of two mode select pins that
selects the operation of the serial port/DSP interface when RESET is deasserted.
Off-Hook.
An active low input control signal that provides a termination across TIP and RING for
line seizing and pulse dialing,
