In this mode, the ADC automatically scans the input voltage on the analog input channels and asserts the ALERT pin when the programmable high or low thresholds are crossed. The conversion results of the ADC corresponding to the pre-ALERT or post-ALERT can be stored in the internal data buffer, as described in Section 7.4.3.1.1 and Section 7.4.3.1.2 respectively. This mode is useful for applications where the output of the sensor must be continuously monitored and where action is only taken when the sensor output deviates outside of an acceptable range.
