INT
O
Interrupt Output.
This pin is asserted 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 command control register.
NOTE: This pin is an open drain output and requires an external 10K
pull-up
resistor.

I
In-Circuit Testing (Active Low).
When this pin is tied Low, all output pins are forced to high impedance state for
in-circuit testing.
NOTE: Internally pulled -up with 50k
.

LOOPSEL
I
DLoop-back Mode Select.
In Hardware Mode, if LOOPEN_(0-3) is “High”, this pin is used for selecting
loop-back mode. Connect this pin "High" to select local loop-back and Low to
select remote loop-back. Digital Loop-back is not supported in Hardware Mode.

Loop-back Enable - Channel_n:
In Hardware Mode:
Connect this pin “High” to enable channel_n loop-back operation. Remote or
local loop-back is determined by pin 58 setting.

FIFOS
I
FIFO Size Select.
In Hardware Mode, connect this pin "High" selects 64 bit FIFO depth and con-
nect Low to select 32 bit FIFO depth.
