    1. The SysTick_Config() function is a CMSIS function which configure:
       - The SysTick Reload register with value passed as function parameter.
       - Configure the SysTick IRQ priority to the lowest value (0x0F).
       - Reset the SysTick Counter register.
       - Configure the SysTick Counter clock source to be Core Clock Source (HCLK).
       - Enable the SysTick Interrupt.
       - Start the SysTick Counter.
    
    2. You can change the SysTick IRQ priority by calling the
       NVIC_SetPriority(SysTick_IRQn,...) just after the SysTick_Config() function 
       call. The NVIC_SetPriority() is defined inside the core_cm0.h file.

    3. 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 SysTick_Config() function
       - Reload Value should not exceed 0xFFFFFF
