Address Bus Input Pins/Jitter Attenuator Select Input Pins/Equalizer
Control Input pins:
The exact function of these input pins depends upon whether the XRT83L34
device has been configured to operate in the HOST or Hardware Mode, as
described below.
HOST Mode Operation - Address Bus Input Pins - A[6:0]:
These pins permits the Microprocessor to identity on-chip registers (within
the XRT83L34 device0 whenever it performs READ and WRITE operations
with the XRT83L34 device.

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
"0" in the command 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
pull-
up resistor.
