ALERT RESPONSE ADDRESS
Alert Response Address (ARA) is a feature of SMBus devices
that allows an interrupting device to identify itself to the host
when multiple devices exist on the same bus.
The INT output can be used as an interrupt output or can be
used as an SMBALERT. One or more INT outputs can be
connected to a common SMBALERT line connected to the
master. If a device’s INT line goes low, the following procedure
occurs:
1.
SMBALERT is pulled low.
2.
Master initiates a read operation and sends the Alert
Response Address (ARA = 0001 100). This is a general call
address that must not be used as a specific device address.
3.
The device whose INT output is low responds to the alert
response address, and the master reads its device address.
The address of the device is now known and can be
interrogated in the usual way.
4.
If more than one device’s INT output is low, the one with
the lowest device address has priority, in accordance with
normal SMBus arbitration.
5.
Once the ADM1031 has responded to the alert response
address, it resets its INT output. However, if the error
condition that caused the interrupt persists, then INT is
reasserted on the next monitoring cycle.
