the ALERT is cleared by responding to the alert
response address and the temperature fault condition
still exists, ALERT is reasserted after the next tempera-
ture-monitoring cycle. To clear ALERT while the tempera-
ture is above the trip threshold, write a new high limit that
is higher than the current temperature. The ALERT out-
put is open drain, allowing multiple devices to share a
common interrupt line.
Alert Response Address
The SMBus alert response interrupt pointer provides
quick fault identification for simple slave devices like
temperature sensors. Upon receiving an ALERT inter-
rupt signal, the host master can broadcast a Receive
Byte transmission to the alert response slave address
(0001 100). Following such a broadcast, any slave
device that generated an interrupt attempts to identify
itself by putting its own address on the bus.
The alert response can activate several different slave
devices simultaneously, similar to the I
2
C General Call.
If more than one slave attempts to respond, bus arbitra-

A 1 disables local temperature measurements so that only
remote temperature is measured. The measurement rate
becomes 8Hz.
