ALARM_TEMP_PL_LOWER (PLSYSMON) Register Description

Register NameALARM_TEMP_PL_LOWER
Relative Address0x0000000150
Absolute Address 0x00FFA50D50 (AMS_PL_SYSMON)

DescriptionPL Lower temperature Lower Alarm Threshold and config.

The temperature Alarm will be set when the PL measured temperature exceeds the value in ALARM_TEMP_PL_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_TEMP_PL_LOWER. 1: Alarm is cleared when temperature falls below ALARM_TEMP_PL_UPPER.
