For STM32 timers, PWM frequency is calculated using the following equation, 

Where:

·      f _TIM = System clock frequency 

·       PSC = Prescaler value

·       ARR = Counter Period (Auto-Reload Register value) = 5999 

What will be the Prescaler value which will result in PWM time period of 3ms?
