152  ##### Initialization and de-initialization functions #####
153  ===============================================================================
154  [..] This section provides functions allowing to:
155  (+) Initialize the Flash interface, the NVIC allocation and initial clock
156  configuration. It also initializes the source of time base when timeout
157  is needed.
158  (+) De-initialize common part of the HAL.
159  (+) Configure The time base source to have 1ms time base with a dedicated
160  Tick interrupt priority.
161  (++) SysTick timer is used by default as source of time base, but user can
162  eventually implement his or her proper time base source (a general purpose
163  timer for example or other time source), keeping in mind that Time base
164  duration should be kept as 1ms since PPP_TIMEOUT_VALUEs are defined and
165  handled in milliseconds basis.
166  (++) Time base configuration function (hal_init_tick()) is called automatically
167  at the beginning of the program after reset by hal_init().
168  (++) Source of time base is configured to generate interrupts at regular
169  time intervals. Care must be taken if hal_delay() is called from a
170  peripheral ISR process, the Tick interrupt line must have higher priority
171  (numerically lower) than the peripheral interrupt. Otherwise the caller
172  ISR process will be blocked.
173  (++) Functions affecting time base configurations are declared as __Weak
174  to make override possible in case of other implementations in user file.
