                     ##### How to use this driver #####
  ==============================================================================
    [..]
    The common HAL driver contains a set of generic and common APIs that can be
    used by the PPP peripheral drivers and the user to start using the HAL.
    [..]
    The HAL contains two APIs' categories:
         (+) Common HAL APIs
         (+) Services HAL APIs
