8.5.11 Out-Of-Range ADC Thresholds: Address 0x80 – 0x93

The unipolar analog inputs (LV_ADC12 to LV_ ADC16) and the local temperature sensor implement an out-of-

range alarm function. The Upper-Thresh and Lower-Thresh registers define the upper bound and lower bounds

for these inputs. This window determines whether the analog input or temperature is out-of-range. When the

input is outside the window, the corresponding CH-ALR-n bit in the Status Register is set to '1'. For normal

operation, the value of the upper threshold must be greater than the value of lower threshold; otherwise, an

alarm is always indicated. The analog input threshold values are specified in straight binary format while the local

temperature ones are specified in two’s complement format.
