  The user should identify which mode will be used in his application to manage   
  the ADC controller events: Polling mode or Interrupt mode.
  
  In the Polling Mode it is advised to use the following functions:
      - ADC_GetFlagStatus() : to check if flags events occur. 
      - ADC_ClearFlag()     : to clear the flags events.
      
  In the Interrupt Mode it is advised to use the following functions:
     - ADC_ITConfig()       : to enable or disable the interrupt source.
     - ADC_GetITStatus()    : to check if Interrupt occurs.
     - ADC_ClearITPendingBit() : to clear the Interrupt pending Bit 
                                (corresponding Flag).
