Alarm Control Tab
The alarm control options for the four different analog sensors can be controlled from this tab (see
). The options can be changed only if the corresponding sensor is enabled in the "Gen. Device
Config" tab.

1. Averaging Mode
True averaging is done only if the "Average" option is selected. The Lowest or Highest options store
only the lowest or highest, respectively, sample for the selected sensor. The number of samples done
before the result is stored is set in the "Averaging Register" setting on the "Gen. Device Config" tab.
The "First" option stores the first sample of the selected sensor. If averaging is selected, during
sampling passes after the first sample was stored, the remaining passes will skip this sensor.
2. Enable Alarm Monitor
Enables a check for high or low thresholds for a particular sensor. The results are given in the labels
below.
3. Enable Alarm Interrupt
Enables a GPIO interrupt if a high or low threshold has been exceeded. The "Enable Alarm Monitor"
must also be selected for this to take effect.
4. Stored Sample Memory
Defines the length of the logged samples memory section.
5. Total Number Of Stores
Reports how many samples were written to the log memory.
6. Sample Buffer Index
Reports the index location of the last sample stored.
7. FRAM Virtual Registers Initialized
If checked, indicates that the FRAM memory has been initialized.
