Synchronous Microprocessor Clock/Automatic Transmit All Ones
Host Mode
This synchronous input clock is used as the internal master clock to the microproces-
sor interface when configured for in a synchronous mode.
Hardware Mode
This pin is used select an all ones signal to the line interface through TTIP/TRING any
time that a loss of signal occurs. This feature is avaiable in Host mode by program-
ming the appropriate global register.

Interrupt Output
Host Mode
This signal is asserted "Low" when a change in alarm status occurs. Once the status
registers have been read, the interrupt pin will return "High". GIE (Global Interrupt
Enable) must be set "High" in the appropriate global register to enable interrupt gen-
eration.
N
OTES
:
1.
This pin is an open-drain output that requires an external 10K
pull-up
resistor.

This pin has an internal PULL-DOWN 50k
resistor
