  * @brief   TIM HAL module driver.
  *          This file provides firmware functions to manage the following
  *          functionalities of the Timer extension peripheral:
  *           + Time Master and Slave synchronization configuration
  *           + Timer remapping capabilities configuration
  @verbatim
  ==============================================================================
                      ##### TIMER Extended features #####
  ==============================================================================
  [..]
    The Timer Extension features include:
    (#) Synchronization circuit to control the timer with external signals and to
        interconnect several timers together.
    (#) Timer remapping capabilities configuration
