Detailed Description

Interrupts and flags management functions.

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

    [..] This section provides functions allowing to configure the ADC Interrupts,
         get the status and clear flags and Interrupts pending bits.
  
    [..] The ADC provide 4 Interrupts sources and 9 Flags which can be divided
         into 3 groups:
  
  *** Flags and Interrupts for ADC regular channels ***
  =====================================================
    [..]
        (+)Flags :
           (##) ADC_FLAG_EOC : Regular channel end of conversion to indicate 
                the end of sequence of regular GROUP conversions
           (##) ADC_FLAG_STRT: Regular channel start to indicate when regular
                CHANNEL conversion starts.

        (+)Interrupts :
           (##) ADC_IT_EOC : specifies the interrupt source for Regular channel
                end of conversion event.
  
  
  *** Flags and Interrupts for ADC Injected channels ***
  ======================================================
    [..]
        (+)Flags :
           (##) ADC_FLAG_JEOC : Injected channel end of conversion to indicate
                at the end of injected GROUP conversion
           (##) ADC_FLAG_JSTRT : Injected channel start to indicate when injected
                GROUP conversion starts.

        (+)Interrupts :
           (##) ADC_IT_JEOC : specifies the interrupt source for Injected channel
                end of conversion event.

  *** General Flags and Interrupts for the ADC ***
  ================================================
    [..]
        (+)Flags :
           (##) ADC_FLAG_AWD : Analog watchdog + to indicate if the converted voltage
                              crosses the programmed thresholds values.
        (+)Interrupts :
           (##) ADC_IT_AWD : 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).
