|     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 | ||||

|     [..]  This section provides functions allowing to: | ||||
|       (+) Initializes the Flash interface the NVIC allocation and initial clock  | ||||
|           configuration. It initializes the systick also when timeout is needed  | ||||
|           and the backup domain when enabled. | ||||
|       (+) De-Initializes common part of the HAL. | ||||
|       (+) Configure the time base source to have 1ms time base with a dedicated  | ||||
|           Tick interrupt priority.  | ||||
|         (++) SysTick timer is used by default as source of time base, but user | ||||
|              can eventually implement his proper time base source (a general purpose  | ||||
|              timer for example or other time source), keeping in mind that Time base  | ||||
|              duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and  | ||||
|              handled in milliseconds basis. | ||||
|         (++) Time base configuration function (HAL_InitTick ()) is called automatically  | ||||
|              at the beginning of the program after reset by HAL_Init() or at any time  | ||||
|              when clock is configured, by HAL_RCC_ClockConfig().  | ||||
|         (++) Source of time base is configured  to generate interrupts at regular  | ||||
|              time intervals. Care must be taken if HAL_Delay() is called from a  | ||||
|              peripheral ISR process, the Tick interrupt line must have higher priority  | ||||
|             (numerically lower) than the peripheral interrupt. Otherwise the caller  | ||||
|             ISR process will be blocked.  | ||||
|        (++) functions affecting time base configurations are declared as __weak   | ||||
|              to make  override possible  in case of other  implementations in user file. | ||||
