210 ##### Initialization and de-initialization functions #####
211 ===============================================================================
212 [..] This section provides functions allowing to:
213 (+) Initialize the Flash interface, the NVIC allocation and initial clock
214 configuration. It also initializes the source of time base when timeout
215 is needed.
216 (+) De-initialize common part of the HAL.
217 (+) Configure The time base source to have 1ms time base with a dedicated
218 Tick interrupt priority.
219 (++) SysTick timer is used by default as source of time base, but user can
220 eventually implement his or her proper time base source (a general purpose
221 timer for example or other time source), keeping in mind that Time base
222 duration should be kept as 1ms since PPP_TIMEOUT_VALUEs are defined and
223 handled in milliseconds basis.
224 (++) Time base configuration function (hal_init_tick()) is called automatically
225 at the beginning of the program after reset by hal_init().
226 (++) Source of time base is configured to generate interrupts at regular
227 time intervals. Care must be taken if hal_delay() is called from a
228 peripheral ISR process, the Tick interrupt line must have higher priority
229 (numerically lower) than the peripheral interrupt. Otherwise the caller
230 ISR process will be blocked.
231 (++) Functions affecting time base configurations are declared as __Weak
232 to make override possible in case of other implementations in user file.
