Description
Chip enable for external A/D converter, true = low.
8 bit serial input for external A/D.
Interrupt to controller to read A/D data, true = high.
Clock for A/D converter.
Advance or retard the chip phase. High = advance.
General purpose bi-directional port for microcontroller interface.

General purpose bi-directional port for microcontroller interface.
General purpose bi-directional port for microcontroller interface.
Address Latch Enable for port AD. Down edge latches.
Can drive dial pulse relay or other function.
Driver for audio track and hold.
Replica of MCLK high speed clock input, for driving microcontroller
clock input.
Internal data path, high = carrier present.
Can control a VCC switch to turn on and off the other circuits.
Indicates whether the tau-dither state is retarded or not retarded. High
= retarded.
A programmable transition on this pin will cause the chip to wake-up.
May be used to control RF receive gain.
