Control Register Demonstration
The drop-down box labeled Select Cell Count determines the number of cell voltage measurements that
are displayed: 1 to 6. This function is independent of the cell count. For example, if the user only wanted
to display 3 cells of a 6-cell pack, then the Select Cell Count box is changed to 3. This convenience
feature avoids seeing a somewhat random number being displayed for unconnected cell inputs.
