             ##### 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.
        (#) 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.
        
        (#) Enable and Configure the priority of the selected IRQ Channels.
   [..]
   (@) When the NVIC_PriorityGroup_0 is selected, it will no any nested interrupt,
       the IRQ priority will be managed only by subpriority.
       The sub-priority is only used to sort pending exception priorities, 
       and does not affect active exceptions.
   (@) Lower priority values gives higher priority.
   (@) Priority Order:
       (#@) Lowest Preemption priority.
       (#@) Lowest Subpriority.
       (#@) Lowest hardware priority (IRQn position).
