The
(ARA=0001 100) sent by the host if the out of limit condition no longer exists, but it does not reset if
the error condition remains. The
event of an out of limit temperature measurement, except when it is configured as a second
pin.
The
measurement exceeds the Temperature High Limit value. In this mode, the output will not de-assert
until the temperature drops below the Temperature High Limit minus the THERM Hysteresis value.
The
