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
output clears if the
temperature goes below the high-temperature limit
threshold. 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.
