- TIM7CLK = PCLK1 = HCLK = SystemCoreClock
-
- With Prescaler set to 479 and Period to 24999, the TIM7 counter is updated each 250 ms
- (i.e. and interrupt is generated each 250 ms)

- ==> TIM7 counter period = 250 ms

- Note:
- SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f0xx.c file.
- Each time the core clock (HCLK) changes, user had to call SystemCoreClockUpdate()
- function to update SystemCoreClock variable value. Otherwise, any configuration
- based on this variable will be incorrect.
