23     [..]
24     The common HAL driver contains a set of generic and common APIs that can be
25     used by the PPP peripheral drivers and the user to start using the HAL.
26     [..]
27     The HAL contains two APIs' categories:
28          (+) Common HAL APIs
29          (+) Services HAL APIs

108            ##### HAL Initialization and Configuration functions #####
109  ===============================================================================
110     [..]  This section provides functions allowing to:
111       (+) Initialize the Flash interface the NVIC allocation and initial time base
112           clock configuration.
113       (+) De-initialize common part of the HAL.
114       (+) Configure the time base source to have 1ms time base with a dedicated
115           Tick interrupt priority.
116         (++) SysTick timer is used by default as source of time base, but user
117              can eventually implement his proper time base source (a general purpose
118              timer for example or other time source), keeping in mind that Time base
119              duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
120              handled in milliseconds basis.
121         (++) Time base configuration function (HAL_InitTick ()) is called automatically
122              at the beginning of the program after reset by HAL_Init() or at any time
123              when clock is configured, by HAL_RCC_ClockConfig().
124         (++) Source of time base is configured  to generate interrupts at regular
125              time intervals. Care must be taken if HAL_Delay() is called from a
126              peripheral ISR process, the Tick interrupt line must have higher priority
127             (numerically lower) than the peripheral interrupt. Otherwise the caller
128             ISR process will be blocked.
129        (++) functions affecting time base configurations are declared as __weak
130              to make  override possible  in case of other  implementations in user file.

139   *           Configure the Flash prefetch, instruction and Data caches.
140   *           Configures the SysTick to generate an interrupt each 1 millisecond,
141   *           which is clocked by the MSI (at this stage, the clock is not yet
