3.8.3.21

Minimum and Maximum Values of Current and Voltage

For current and voltage measurements, the minimum and maximum values are determined on the upper 16 bits

of the corresponding conversion results. These values can be read from registers adcCmax, adcCmin,

adcVmax,

and adcVmin. These registers are reset in the same manner as the corresponding accumulator

registers. These values are only provided for statistical reasons and can be used to assess the accumulated

current or voltage values when used for mean value calculation.

Note: As the minimum and maximum values are only determined on the 16 MSBs of the corresponding con-

version results, it might be beneficial to use the post correction gain functionality to shift left the results to

increase the accuracy of the comparison.
