+    In this example TIM2 input clock (TIM2CLK)  is set to APB1 clock (PCLK1),
+    since APB1 prescaler is equal to 1.
+      TIM2CLK = PCLK1
+      PCLK1 = HCLK
+      => TIM2CLK = HCLK = SystemCoreClock
+    To get TIM2 counter clock at 10 KHz, the Prescaler is computed as following:
+    Prescaler = (TIM2CLK / TIM2 counter clock) - 1
+    Prescaler = (SystemCoreClock /10 KHz) - 1
+
+    Note:
+     SystemCoreClock variable holds HCLK frequency and is defined in system_stm32wbxx.c file.
+     Each time the core clock (HCLK) changes, user had to update SystemCoreClock
+     variable value. Otherwise, any configuration based on this variable will be incorrect.
+     This variable is updated in three ways:
+      1) by calling CMSIS function SystemCoreClockUpdate()
+      2) by calling HAL API function HAL_RCC_GetSysClockFreq()
+      3) each time HAL_RCC_ClockConfig() is called to configure the system clock frequency
