  ==============================================================================
                      ##### TIMER Extended features #####
  ==============================================================================
  [..] 
    The Timer Extension features include: 
    (#) Complementary outputs with programmable dead-time for :
        (++) Input Capture
        (++) Output Compare
        (++) PWM generation (Edge and Center-aligned Mode)
        (++) One-pulse mode output
    (#) Synchronization circuit to control the timer with external signals and to 
        interconnect several timers together.
    (#) Break input to put the timer output signals in reset state or in a known state.
    (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for 
        positioning purposes                
   
                        ##### How to use this driver #####
  ==============================================================================
  [..]
     (#) Initialize the TIM low level resources by implementing the following functions 
         depending from feature used :
           (++) Complementary Output Compare : HAL_TIM_OC_MspInit()
           (++) Complementary PWM generation : HAL_TIM_PWM_MspInit()
           (++) Complementary One-pulse mode output : HAL_TIM_OnePulse_MspInit()
           (++) Hall Sensor output : HAL_TIM_HallSensor_MspInit()
           
     (#) Initialize the TIM low level resources :
        (##) Enable the TIM interface clock using __TIMx_CLK_ENABLE(); 
        (##) TIM pins configuration
            (+++) Enable the clock for the TIM GPIOs using the following function:
                 __GPIOx_CLK_ENABLE();   
            (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();  
  
     (#) The external Clock can be configured, if needed (the default clock is the 
         internal clock from the APBx), using the following function:
         HAL_TIM_ConfigClockSource, the clock configuration should be done before 
         any start function.
  
    (#) Configure the TIM in the desired functioning mode using one of the 
        initialization function of this driver:
        (++) HAL_TIMEx_HallSensor_Init and HAL_TIMEx_ConfigCommutationEvent: to use the 
             Timer Hall Sensor Interface and the commutation event with the corresponding 
             Interrupt and DMA request if needed (Note that One Timer is used to interface 
             with the Hall sensor Interface and another Timer should be used to use 
             the commutation event).
  
    (#) Activate the TIM peripheral using one of the start functions: 
           (++) Complementary Output Compare : HAL_TIMEx_OCN_Start(), HAL_TIMEx_OCN_Start_DMA(), HAL_TIMEx_OC_Start_IT()
           (++) Complementary PWM generation : HAL_TIMEx_PWMN_Start(), HAL_TIMEx_PWMN_Start_DMA(), HAL_TIMEx_PWMN_Start_IT()
           (++) Complementary One-pulse mode output : HAL_TIMEx_OnePulseN_Start(), HAL_TIMEx_OnePulseN_Start_IT()
           (++) Hall Sensor output : HAL_TIMEx_HallSensor_Start(), HAL_TIMEx_HallSensor_Start_DMA(), HAL_TIMEx_HallSensor_Start_IT().
