+ [..]
+ 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

+ [..] 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.
