   * @brief   CORTEX HAL module driver.
   *          This file provides firmware functions to manage the following
   *          functionalities of the CORTEX:
   *           + Initialization and de-initialization functions
   *           + Peripheral Control functions
   *
   @verbatim
   ==============================================================================
                         ##### How to use this driver #####
   ==============================================================================
     [..]
     *** How to configure Interrupts using CORTEX HAL driver ***
     ===========================================================
     [..]
     This section provides functions allowing to configure the NVIC interrupts (IRQ).
     The Cortex-M3 exceptions are managed by CMSIS functions.
     (#) Configure the NVIC Priority Grouping using HAL_NVIC_SetPriorityGrouping()
         function according to the following table.
     (#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority().
     (#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ().
     (#) please refer to programming manual for details in how to configure priority.
      -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ preemption is no more possible.
          The pending IRQ priority will be managed only by the sub priority.
      -@- IRQ priority order (sorted by highest to lowest priority):
         (+@) Lowest preemption priority
         (+@) Lowest sub priority
         (+@) Lowest hardware priority (IRQ number)
     [..]
     *** How to configure Systick using CORTEX HAL driver ***
     ========================================================
     [..]
     Setup SysTick Timer for time base.
    (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
        is a CMSIS function that:
         (++) Configures the SysTick Reload register with value passed as function parameter.
         (++) Configures the SysTick IRQ priority to the lowest value 0x0F.
         (++) Resets the SysTick Counter register.
         (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
         (++) Enables the SysTick Interrupt.
         (++) Starts the SysTick Counter.
    (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
        __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
        HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
        inside the stm32f1xx_hal_cortex.h file.
    (+) You can change the SysTick IRQ priority by calling the
        HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
        call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
    (+) To adjust the SysTick time base, use the following formula:
        Reload Value = SysTick Counter Clock (Hz) x  Desired Time base (s)
        (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
        (++) Reload Value should not exceed 0xFFFFFF
