  *                        How to configure Interrupts using driver 
  *          ===================================================================      
  * 
  *            This section provide functions allowing to configure the NVIC interrupts （IRQ）.
  *            The Cortex-M4 exceptions are managed by CMSIS functions.
  *
  *            1. Configure the NVIC Priority Grouping using NVIC_PriorityGroupConfig（）
  *                function according to the following table.
 
  *  The table below gives the allowed values of the pre-emption priority and subpriority according
  *  to the Priority Grouping configuration performed by NVIC_PriorityGroupConfig function
  *    ==========================================================================================================================
  *      NVIC_PriorityGroup   | NVIC_IRQChannelPreemptionPriority | NVIC_IRQChannelSubPriority  |       Description
  *    ==========================================================================================================================
  *     NVIC_PriorityGroup_0  |                0                  |            0-15             | 0 bits for pre-emption priority
  *                           |                                   |                             | 4 bits for subpriority
  *    --------------------------------------------------------------------------------------------------------------------------
  *     NVIC_PriorityGroup_1  |                0-1                |            0-7              | 1 bits for pre-emption priority
  *                           |                                   |                             | 3 bits for subpriority
  *    --------------------------------------------------------------------------------------------------------------------------    
  *     NVIC_PriorityGroup_2  |                0-3                |            0-3              | 2 bits for pre-emption priority
  *                           |                                   |                             | 2 bits for subpriority
  *    --------------------------------------------------------------------------------------------------------------------------    
  *     NVIC_PriorityGroup_3  |                0-7                |            0-1              | 3 bits for pre-emption priority
  *                           |                                   |                             | 1 bits for subpriority
