Detailed Description

Interrupts and flags management functions.

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

  This section provides functions allowing to configure the ADC Interrupts and 
  get the status and clear flags and Interrupts pending bits.
  
  The ADC provides 3 Interrupt sources and 3 Flags:
  
  Flags :
  ---------- 
     1. ADC_FLAG_OVR : Overrun detection when ADC channel converted data is lost

     2. ADC_FLAG_EOC : End of conversion�- to indicate the end of a regular 
                  CHANNEL conversion or a GROUP conversions, depending of the 
                  ADC Continuous Conversion Mode (Continuous or Single 
                  conversion) and of the DMA usage.
                  Note : if DMA is used, EOC occurs at the end of the sequence 
                         conversion, else it occurs after each conversion
     3. ADC_FLAG_AWD: to indicate if the converted voltage crosses the 
                programmed Analog watchdog thresholds values.

     
  Interrupts :
  ------------
     1. ADC_IT_OVR : specifies the interrupt source for the Overrun detection event.
     2. ADC_IT_EOC : specifies the interrupt source for the End of conversion event.
     3. ADC_IT_AWD : specifies the interrupt source for the Analog watchdog event.
