Description | Lower Alarm Over-Temperature (OT) Threshold and Control for LPD and FPD. |
The temperature alarm will be set when the Temp_LPD or Temp_FPD measured value exceeds the value in ALARM_OT_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_OT_LOWER. 1: Alarm is cleared when temperature falls below ALARM_OT_LOWER. Refer to UG580 for more information.
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
temperature_alarm | 15:1 | rwNormal read/write | 0x0 | Alarm temperature threshold. Programmed register value is compared to the measurement register. Applies only when [threshold_mode] = 0; when hysteresis is enabled, the LPD and FPD over temperature (OT) alarm is cleared when the temperature goes below the [temperature_alarm] threshold. |
threshold_mode | 0 | rwNormal read/write | 0x0 | Lower Threshold, Hysteresis Disable. 0: enable hysteresis. 1: disable hysteresis. |
