cases, the alert is cleared even if the fault condition

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

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.
