-  * @brief   CORTEX HAL module driver.
-  *          This file provides firmware functions to manage the following
-  *          functionalities of the CORTEX:

-    *** How to configure Interrupts using CORTEX HAL driver ***
-    ===========================================================
-    [..]
-    This section provides functions allowing to configure the NVIC interrupts (IRQ).
-    The Cortex-M0 exceptions are managed by CMSIS functions.
-      (#) Enable and Configure the priority of the selected IRQ Channels. 
-             The priority can be 0..3. 
-
-        -@- Lower priority values gives higher priority.
-        -@- Priority Order:
-            (#@) Lowest priority.
-            (#@) Lowest hardware priority (IRQn position).  
-
-      (#)  Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority()
-
-      (#)  Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ()
-      
-      -@-  Negative value of IRQn_Type are not allowed.
-
-
-    [..]
-    *** 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 (0x03).
-        (++) 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 stm32f0xx_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
