  *                                 How to use this driver
  *          ===================================================================
  *          This driver provides functions to configure and initialise the EXTI 
  *          peripheral
  *          These functions are split in 2 groups: 
  *   
  *          1. EXTI configuration: this group includes all needed functions 
  *             to configure the EXTI GPIO ports and pins:
  *                   - Set GPIO pins sensitivity
  *                   - Select GPIO port, GPIO half port and set the GPIO port sensitivity
  *                         
  *          2. EXTI interrupt status management
  *                   - Get the interrupt status: set/reset
  *                   - Clear interrupt pending bits
  *
