Description
Reserved for factory use
The ALARMIN-ALR is set to 1 if the ALARMIN pin is enabled
and set high.
Thermal alarm flag. When the die temperature is equal to or
greater than +150°C, the bit is set (1) and the THERM-ALR flag
activates. The on-chip temperature sensor (LT) monitors the die
temperature. If LT is disabled, the THERM-ALR bit is always 0.
The hysteresis of this alarm is 8°C.
LT-HIGH-ALR = 1 when the temperature sensor is out of the
range defined by the upper threshold.
LT-LOW-ALR = 1 when the temperature sensor is out of the
range defined by the lower threshold.
