##### 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

##### Initialization and de-initialization functions #####
=======================================================================================================================
[..] 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.
