// @Function      void ADC_viError(void)

//----------------------------------------------------------------------------
// @Description   This is the interrupt service routine for the overwrite 
//                error of the ADC (in standard mode) - the last measurement 
//                result was overwritten - , or the ISR for the end of an 
//                injected conversion - the result of the injected conversion 
//                has beenwritten to ADC_DAT2. An overrun is not possible in 
//                channel injection mode; in this case the A/D measurement is 
//                stopped. To get the injected conversion result the user can 
//                call the function ADC_uwReadInject().
//                Please note that you have to add application specific code 
//                to this function.
