In both cases, the alert is cleared even if the fault condi-

tion exists, but the ALERT output reasserts at the end of

the next conversion. The bits indicating the fault for the

OVERT interrupt output clear only on reading the status 2

register even if the fault conditions still exist. Reading the

status 2 register does not clear the OVERT interrupt out-

put. To eliminate the fault condition, either the measured

temperature must drop below the temperature threshold

minus the hysteresis value (4°C), or the trip temperature

must be set at least 4°C above the current temperature.
