Lower Critical Threshold
The hysteresis values define a reset threshold. For upper thresholds, the
measurement must fall past this reset threshold before a deassertion
event is generated. For lower thresholds, the measurement must rise
above this reset threshold before a deassertion event is generated.
What is Assertion Timeout?
When the assertion timeout is enabled, the EMX device asserts any
warning or critical condition only after a specified number of consecutive
samples that cross a particular threshold are generated. This prevents a
number of threshold alerts from being generated if the measurements
return to normal immediately after rising above any upper threshold or
dropping below any lower threshold.
