Status Register Functions
There are four status registers (see Tables 7–10). The
ALERT High Status register indicates whether a mea-
sured local or remote temperature has exceeded the
associated threshold limit set in an ALERT High Limit
register. The OVERT Status register indicates whether
a measured temperature has exceeded the associated
threshold limit set in an OVERT High Limit register. The
Diode Fault Status register indicates whether there is a
diode fault (open or short) in any of the remote-sensing
channels. The ALERT Low Status register indicates
whether the measured temperature has fallen below the
threshold limit set in the ALERT Low Limits register for
the local or remote-sensing diodes.
Bits in the alert status registers are cleared by a success-
ful read, but set again after the next conversion unless
the fault is corrected, either by a drop in the measured
temperature or a change in the threshold temperature.
The ALERT interrupt output follows the status flag bit.
Once the ALERT output is asserted, it can be deasserted
by either reading the ALERT High Status register or by
successfully responding to an alert response address. In
both cases, the alert is cleared even if the fault condition
exists, but the ALERT output reasserts at the end of the
next conversion.
The bits indicating OVERT faults clear only when the
measured temperature drops below the temperature
threshold minus the hysteresis value (4NC), or when the
trip temperature is set to a value at least 4NC above the
current temperature.

exceeds the temperature threshold limit in the Local ALERT High Limit register.
5
Remote ALERT
High 6
0
Channel 6 Remote-Diode High-Alert Bit. This bit is set to logic 1 when the channel 6
remote-diode temperature exceeds the programmed temperature threshold limit in the
Remote 6 ALERT High Limit register.
4
Remote ALERT
High 5
0
