Overview
ATmega8HVA/16HVA features a dedicated Sigma-Delta ADC (CC-ADC) optimized for Coulomb
Counting. By sampling the voltage across an external sense resistor R
SENSE, the CC-ADC is
used to track the flow of current going into and out of the battery cells.

In normal conversion mode two different output values are provided, Instantaneous Current and
Accumulate Current. The Instantaneous Current Output has a short conversion time at the cost
