Detailed Description

Interrupts and flags management functions.

 ===============================================================================
                   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:
  
  I. Flags and Interrupts for ADC regular channels
  =================================================
  Flags :
  ---------- 
     1. ADC_FLAG_OVR : Overrun detection when regular converted data are lost

     2. ADC_FLAG_EOC : 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 .

     3. ADC_FLAG_STRT: Regular channel start ==> to indicate when regular CHANNEL 
              conversion starts.

  Interrupts :
  ------------
     1. ADC_IT_OVR : specifies the interrupt source for Overrun detection event.  
     2. ADC_IT_EOC : specifies the interrupt source for Regular channel end of 
                     conversion event.
  
  
  II. Flags and Interrupts for ADC Injected channels
  =================================================
  Flags :
  ---------- 
     1. ADC_FLAG_JEOC : Injected channel end of conversion ==> to indicate at 
               the end of injected GROUP conversion  
              
     2. ADC_FLAG_JSTRT: Injected channel start ==> to indicate hardware when 
               injected GROUP conversion starts.

  Interrupts :
  ------------
     1. ADC_IT_JEOC : specifies the interrupt source for Injected channel end of 
                      conversion event.     

  III. General Flags and Interrupts for the ADC
  ================================================= 
  Flags :
  ---------- 
     1. ADC_FLAG_AWD: Analog watchdog ==> to indicate if the converted voltage 
              crosses the programmed thresholds values.
              
  Interrupts :
  ------------
     1. 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).
