ALERT
ALERT INTERRUPT BEHAVIOR
The ADM1033 generates an ALERT to signal out-of-limit
conditions. Out-of-limit conditions can also be detected by
polling the status registers. The ADM1033 has two ALERT
outputs, called ALERT Comp and SMBusALERT.
In SMBusALERT mode, the output remains low until the
following combination of conditions occur: the measurement
falls back within its programmed limits, and either the status
register is read or an ARA is completed.
In ALERT Comp mode, the output automatically resets
once the temperature measurement falls back within the
programmed limits.
For the SMBusALERT output, a status bit is set when a
measurement goes outside its programmed limit. If the
corresponding mask bit is not set, the SMBusALERT output
is pulled low. If the measured value falls back within the limits,
the SMBusALERT output remains low until the corresponding
status register is read or until an ARA is completed, as long as
no other measurement is outside its limits.
On the other hand, the ALERT Comp output is automatically
pulled low when a measurement goes outside its programmed
limits. Once the measurement falls back within its limits, the
ALERT output is automatically pulled back high again,
assuming no other measurement channel is outside its limits.
The main difference between the two outputs is that the
SMBusALERT does not reset without software intervention,
while the ALERT Comp output automatically resets itself. Note:
In this data sheet, an ALERT refers to both the ALERT Comp
and SMBusALERT, unless otherwise stated.
