  16.   ==============================================================================
  17.                       ##### TIMER Extended features #####
  18.   ==============================================================================
  19.   [..]
  20.     The Timer Extended features include:
  21.     (#) Complementary outputs with programmable dead-time for :
  22.         (++) Output Compare
  23.         (++) PWM generation (Edge and Center-aligned Mode)
  24.         (++) One-pulse mode output
  25.     (#) Synchronization circuit to control the timer with external signals and to
  26.         interconnect several timers together.
  27.     (#) Break input to put the timer output signals in reset state or in a known state.
  28.     (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for
  29.         positioning purposes
  30.  
  31.             ##### How to use this driver #####
  32.   ==============================================================================
  33.     [..]
  34.      (#) Initialize the TIM low level resources by implementing the following functions
  35.          depending from feature used :
  36.            (++) Complementary Output Compare : HAL_TIM_OC_MspInit()
  37.            (++) Complementary PWM generation : HAL_TIM_PWM_MspInit()
  38.            (++) Complementary One-pulse mode output : HAL_TIM_OnePulse_MspInit()
  39.            (++) Hall Sensor output : HAL_TIMEx_HallSensor_MspInit()
  40.  
  41.      (#) Initialize the TIM low level resources :
  42.         (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
  43.         (##) TIM pins configuration
  44.             (+++) Enable the clock for the TIM GPIOs using the following function:
  45.               __HAL_RCC_GPIOx_CLK_ENABLE();
  46.             (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
  47.  
  48.      (#) The external Clock can be configured, if needed (the default clock is the
  49.          internal clock from the APBx), using the following function:
  50.          HAL_TIM_ConfigClockSource, the clock configuration should be done before
  51.          any start function.
  52.  
  53.      (#) Configure the TIM in the desired functioning mode using one of the
  54.          initialization function of this driver:
  55.           (++) HAL_TIMEx_HallSensor_Init and HAL_TIMEx_ConfigCommutationEvent: to use the
  56.               Timer Hall Sensor Interface and the commutation event with the corresponding
  57.               Interrupt and DMA request if needed (Note that One Timer is used to interface
  58.              with the Hall sensor Interface and another Timer should be used to use
  59.              the commutation event).
  60.  
  61.      (#) Activate the TIM peripheral using one of the start functions:
  62.            (++) Complementary Output Compare : HAL_TIMEx_OCN_Start(), HAL_TIMEx_OCN_Start_DMA(), HAL_TIMEx_OCN_Start_IT()
  63.            (++) Complementary PWM generation : HAL_TIMEx_PWMN_Start(), HAL_TIMEx_PWMN_Start_DMA(), HAL_TIMEx_PWMN_Start_IT()
  64.            (++) Complementary One-pulse mode output : HAL_TIMEx_OnePulseN_Start(), HAL_TIMEx_OnePulseN_Start_IT()
  65.            (++) Hall Sensor output : HAL_TIMEx_HallSensor_Start(), HAL_TIMEx_HallSensor_Start_DMA(), HAL_TIMEx_HallSensor_Start_IT().
