Detailed Description

Analog Watchdog configuration functions. 

 ===============================================================================
                    ##### Analog Watchdog configuration functions #####
 ===============================================================================  

  [..] This section provides functions allowing to configure the 3 Analog Watchdogs 
       (AWDG1, AWDG2 and AWDG3) in the ADC.
  
  [..] A typical configuration Analog Watchdog is done following these steps :
   (#) The ADC guarded channel(s) is (are) selected using the functions: 
      (++) ADC_AnalogWatchdog1SingleChannelConfig().
      (++) ADC_AnalogWatchdog2SingleChannelConfig().
      (++) ADC_AnalogWatchdog3SingleChannelConfig().

   (#) The Analog watchdog lower and higher threshold are configured using the functions: 
      (++) ADC_AnalogWatchdog1ThresholdsConfig().
      (++) ADC_AnalogWatchdog2ThresholdsConfig().
      (++) ADC_AnalogWatchdog3ThresholdsConfig().

   (#) The Analog watchdog is enabled and configured to enable the check, on one
      or more channels, using the function:
      (++) ADC_AnalogWatchdogCmd().
