The THRESHOLD_H_RESULT and THRESHOLD_L_RESULT threshold result registers are 12 bits, whereas the THRESHOLD_H_EXPONENT and THRESHOLD_L_EXPONENT threshold exponent registers are four bits. The threshold is compared at linear ADC_CODES, as given by the following equations. Therefore, the threshold registers are padded with zeros internally to compare with the ADC_CODES.
or
and
or
Thresholds are then compared as given in the following equations to detect fault events.
and
Based on the FAULT_COUNT register setting, with consecutive fault high or fault low events, the respective FLAG_H and FLAG_L registers are set. See the Interrupt Modes of Operation section for more information. Understanding the relation between the THRESHOLD_H_EXPONENT, THRESHOLD_H_RESULT, THRESHOLD_L_EXPONENT, and THRESHOLD_L_RESULT register bits and the output registers is important to set the appropriate threshold based on application needs.
