Detailed Description
The user can read the registers that monitor the V
CC
,
MON1, MON2, MON3, and temperature analog signals.
After each signal conversion, a corresponding bit is set
that can be monitored to verify that a conversion has
occurred. The signals also have alarm and warning flags
that notify the user when the signals go above or below
the user-defined value. Interrupts can also be set for
each signal.
The position values of each resistor can be indepen-
dently programmed. The user can assign a unique
value to each resistor for every 2°C increment over the
-40°C to +102°C range.
Two buffers are provided to convert logic-level inputs
into open-drain outputs. Typically, these buffers are
used to implement transmit (Tx) fault and loss-of-signal
(LOS) functionality. Additionally, OUT1 can be asserted
in the event that one or more of the monitored values
go beyond user-defined limits.

L0
Low-End Resistor 0 Terminal. It is not required that the low-end terminals be connected to a potential
less than the high-end terminals of the corresponding resistor. Voltage applied to any of the resistor
terminals cannot exceed the power-supply voltage, V
CC
, or go below ground.
