              TIM Driver: how to use it in Timing(Time base) Mode
       =================================================================== 
       To use the Timer in Timing(Time base) mode, the following steps are mandatory:
       
       1. Enable TIM clock using RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function
                    
       2. Fill the TIM_TimeBaseInitStruct with the desired parameters.
       
       3. Call TIM_TimeBaseInit(TIMx, &TIM_TimeBaseInitStruct) to configure the Time Base unit
          with the corresponding configuration
          
       4. Enable the NVIC if you need to generate the update interrupt. 
          
       5. Enable the corresponding interrupt using the function TIM_ITConfig(TIMx, TIM_IT_Update) 
       
       6. Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
             
       Note1: All other functions can be used separately to modify, if needed,
          a specific feature of the Timer.
