// 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 Clock source to be HCLK_Div8 by calling the

// SysTick_CLKSourceConfig(SysTick_CLKSource_HCLK_Div8) just after the

// SysTick_Config() function call. The SysTick_CLKSourceConfig() is defined

// inside the misc.c file.

// 3. 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_cm4.h file.

// 4. 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
