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 Alarm section). Access to these regis-
ters 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 output clears if tem-
perature goes below the high-temperature limit thresh-
old. The ALERT interrupt output signal can also be
cleared by reading the status register(s) associated
with the fault(s) or by successfully responding 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 automatic 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.
