DescriptionLower Alarm Threshold Setting for Temp_PL Over-Temperature (OT).

The PL over temperature (OT) Alarm will be set when the measured temperature exceeds the value in ALARM_OT_UPPER The temperature at which the Alarm will be cleared depends on the [threshold_mode] bit setting: 0: Alarm is cleared when temperature falls below ALARM_OT_LOWER. 1: Alarm is cleared when temperature falls below ALARM_OT_UPPER
