Alarm Threshold Registers
There are 11 alarm threshold registers that store over-
temperature ALERT and OVERT threshold values.
Seven of these registers are dedicated to store one
local alert temperature threshold limit and six remote
alert temperature threshold limits (see the ALERT
Interrupt Mode section). The remaining four registers
are dedicated to remote channels 1, 4, 5, and 6 to store
overtemperature threshold limits (see the OVERT
Overtemperature Alarms section). Access to these reg-
isters is provided through the SMBus interface.
ALERT Interrupt Mode
An ALERT interrupt occurs when the internal or external
temperature reading exceeds a high-temperature limit
(user programmable). The ALERT interrupt output sig-
nal can be cleared by reading the status register(s)
associated with the fault(s) or by successfully respond-
ing to an alert response address transmission by the
master. In both cases, the alert is cleared but is
reasserted at the end of the next conversion if the fault
condition still exists. The interrupt does not halt automat-
ic conversions. The ALERT output is open drain so that
multiple devices can share a common interrupt line. All
ALERT interrupts can be masked using the configuration
3 register. The POR state of these registers is shown in
Table 1.
