+    [..]
+    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:
+         (+) HAL Initialization and de-initialization functions
+         (+) HAL Control functions

+          configuration. It initializes the source of time base 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
