Program flow is diverted here when an error has occurred. Program execution will exit
the error handler when all sources of error have been cleared.
The program flow is illustrated in the figure below.
Figure 4-8. Flow chart of error handler
These functions are called by Charge() after all parameters have been set.
These two functions are similar, apart from what ADC measurements they try to keep
within limits. Therefore, only the flow chart for ConstantCurrent() is illustrated in the
figure below. They both make use of the variable ChargeParameters.
