@par Example Description 

This example describes how to enters the system to SLEEP mode and wake-up from this
mode using IO interrupt.

In the associated software
  - the PC5 is configured to generate interrupt on fallingfalling edge

The system enters SLEEP mode and will wait for the  Key push-button is pressed. 
 - If the KEY button (EXTI_Line15) is the source of wakeup from SLEEP, LED1 is toggled.

This behavior is repeated in an infinite loop.

In this example, Main clock is configured at 24MHz.
