Detailed Description

Vbat, Temperature Sensor & Vrefint (Internal Reference Voltage) management function. 

 ====================================================================================================
  ##### Temperature Sensor - Vrefint (Internal Reference Voltage) and VBAT management functions #####
 ====================================================================================================  

  [..] This section provides a function allowing to enable/ disable the internal 
  connections between the ADC and the Vbat/2, Temperature Sensor and the Vrefint source.

  [..] A typical configuration to get the Temperature sensor and Vrefint channels 
  voltages is done following these steps :
   (#) Enable the internal connection of Vbat/2, Temperature sensor and Vrefint sources 
       with the ADC channels using:
      (++) ADC_TempSensorCmd()  
      (++) ADC_VrefintCmd() 
      (++) ADC_VbatCmd()  

   (#) select the ADC_Channel_TempSensor and/or ADC_Channel_Vrefint and/or ADC_Channel_Vbat using 
      (++) ADC_RegularChannelConfig() or  
      (++) ADC_InjectedInit() functions 

   (#) Get the voltage values, using:
      (++) ADC_GetConversionValue() or  
      (++) ADC_GetInjectedConversionValue().
