            ##### Interrupts and flags management functions #####
 ===============================================================================  

    [..] This section provides functions allowing to configure the ADC Interrupts 
         and to get the status and clear flags and Interrupts pending bits.
  
    [..] Each ADC provides 4 Interrupts sources and 6 Flags which can be divided
        into 3 groups:
  
  *** Flags and Interrupts for ADC regular channels ***
  =====================================================
    [..]
      (+) Flags :
        (##) ADC_FLAG_OVR_MORT : Overrun detection when regular converted data are lost

        (##) ADC_FLAG_EOC_MORT : Regular channel end of conversion ==> to indicate 
             (depending on EOCS bit, managed by ADC_EOCOnEachRegularChannelCmd() )
             the end of:
             (+++) a regular CHANNEL conversion 
             (+++) sequence of regular GROUP conversions .

        (##) ADC_FLAG_STRT_MORT: Regular channel start ==> to indicate when regular 
             CHANNEL conversion starts.
    [..]
      (+) Interrupts :
        (##) ADC_IT_OVR_MORT : specifies the interrupt source for Overrun detection 
             event.  
        (##) ADC_IT_EOC_MORT : specifies the interrupt source for Regular channel end
             of conversion event.
  
  
  *** Flags and Interrupts for ADC Injected channels ***
  ======================================================
    [..]
      (+) Flags :
        (##) ADC_FLAG_JEOC_MORT : Injected channel end of conversion ==> to indicate 
             at the end of injected GROUP conversion  
              
        (##) ADC_FLAG_JSTRT_MORT: Injected channel start ==> to indicate hardware when 
             injected GROUP conversion starts.
    [..]
      (+) Interrupts :
        (##) ADC_IT_JEOC_MORT : specifies the interrupt source for Injected channel 
             end of conversion event.     

  *** General Flags and Interrupts for the ADC ***
  ================================================ 
    [..]
      (+)Flags :
        (##) ADC_FLAG_AWD_MORT: Analog watchdog ==> to indicate if the converted voltage 
             crosses the programmed thresholds values.
    [..]          
      (+) Interrupts :
        (##) ADC_IT_AWD_MORT : specifies the interrupt source for Analog watchdog event. 

  
    [..] 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).
