Loop-back Control Pins, Bits [1:0] Channel_[3:0]
In Hardware mode, pins 67-74 and 173-180 control which Loop-Back mode is
selected per channel.
NOTE: These pins are internally pulled “Low” with a 50k
Ω resistor.

I
Microprocessor Clock Input - Host Mode:
Input clock for synchronous microprocessor operation. Maximum clock rate is 54
MHz.
NOTE:
This pin is internally pulled “Low” with a 50k
Ω resistor for asynchronous
microprocessor interface when no clock is present.
Automatic Transmit “All Ones” - Hardware mode
This pin functions as an Automatic Transmit “All Ones”.

I
Interrupt Output - Host mode
This pin goes “Low” to indicate an alarm condition has occurred within the device.
Interrupt generation can be globally disabled by setting the GIE bit to a “0” in the com-
mand control register.
Transmitter Transformer Ratio Select - Hardware mode
The function of this pin is to select the transmitter transformer ratio.
NOTE: This pin is an open drain output and requires an external 10k
Ω pull-up resistor.
