  *          ===================================================================
  *
  *           Wait for event mode (WFE) stops the CPU but allows the other peripherals
  *           and interrupt controller to continue running.
  *           This mode is entered from Run mode by executing a WFE instruction.
  *           Peripheral events can be generated by the timers, serial interfaces, 
  *           DMA controller, comparators and I/O ports. 
  *           These are enabled by using the WFE_WakeUpSourceEventCmd() function.
  *           
  *           When a peripheral event is enabled, the corresponding interrupts are 
  *           not served and you have to clear the corresponding flag status.
  *           
  *           There are two ways to wake up the CPU from WFE mode:
  *            - Interrupts: When an interrupt occurs, the CPU wakes up from WFE mode
  *              serves the interrupt then goes back to WFE mode.
  *            - Wake up event: when a wake up event occurs, the CPU wakes up and 
  *              resumes processing, in this case and to save time and power consumption
  *              there is no context save/restore activity.            
  *
