  14 ================================================================================
  15           ##### TIM specific features integration #####
  16 ================================================================================
  17
  18     [..] The Timer features include:
  19          (#) 16-bit up, down, up/down auto-reload counter.
  20          (#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock
  21              frequency either by any factor between 1 and 65536.
  22          (#) Up to 4 independent channels for:
  23            Input Capture
  24            Output Compare
  25            PWM generation (Edge and Center-aligned Mode)
  26            One-pulse mode output
  27          (#) Synchronization circuit to control the timer with external signals and to interconnect
  28             several timers together.
  29          (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
  30            purposes
  31
  32             ##### How to use this driver #####
  33 ================================================================================
  34     [..]
  35      (#) Enable the TIM interface clock using
  36          __HAL_RCC_TIMx_CLK_ENABLE();
  37
  38      (#) TIM pins configuration
  39           (++) Enable the clock for the TIM GPIOs using the following function:
  40               __HAL_RCC_GPIOx_CLK_ENABLE();
  41           (++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
  42
  43      (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx),
  44          using the following function:
  45          HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function.
  46
  47      (#) Configure the TIM in the desired operating mode using one of the
  48          configuration function of this driver:
  49           (++) HAL_TIMEx_MasterConfigSynchronization() to configure the peripheral in master mode.
  50
  51      (#) Remap the Timer I/O using HAL_TIMEx_RemapConfig() API.
