ALARM_TEMP_FPD_LOWER (PSSYSMON) Register Description

Register NameALARM_TEMP_FPD_LOWER
Relative Address0x00000001B4
Absolute Address 0x00FFA509B4 (AMS_PS_SYSMON)
Width16
TyperwNormal read/write
Reset Value0x00000000
DescriptionLower Alarm Temperature Threshold and Control for FPD (t-remote).

The temperature alarm will be set when the Temp_FPD measured value exceeds the value in ALARM_TEMP_FPD_UPPER register. 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_FPD_LOWER. 1: Alarm is cleared when temperature falls below ALARM_TEMP_FPD_LOWER. Refer to UG580 for more information.

ALARM_TEMP_FPD_LOWER (PSSYSMON) Register Bit-Field Summary

Field NameBitsTypeReset ValueDescription
temperature_alarm15:1rwNormal read/write0x0Alarm temperature threshold.
Programmed register value is compared to the measurement register.
Applies only when [threshold_mode] = 0; when hysteresis is enabled, the FPD temperature alarm is cleared when the temperature goes below the [temperature_alarm] threshold.
threshold_mode 0rwNormal read/write0x0Lower Threshold, Hysteresis Disable.
0: enable hysteresis.
1: disable hysteresis.
