 ===================================================================          
 [..]
   (#) Enable The RNG controller clock using 
       RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_RNG, ENABLE) function.
                
   (#) Activate the RNG peripheral using RNG_Cmd() function.
            
   (#) Wait until the 32 bit Random number Generator contains a valid  random data
      (using polling/interrupt mode). For more details, refer to "Interrupts and 
      flags management functions" module description.
             
   (#) Get the 32 bit Random number using RNG_GetRandomNumber() function
            
   (#) To get another 32 bit Random number, go to step 3.
