98 ##### HAL Initialization and Configuration functions #####
99 ===============================================================================
100 [..] This section provides functions allowing to:
101 (+) Initialize the Flash interface the NVIC allocation and initial time base
102 clock configuration.
103 (+) De-initialize common part of the HAL.
104 (+) Configure the time base source to have 1ms time base with a dedicated
105 Tick interrupt priority.
106 (++) SysTick timer is used by default as source of time base, but user
107 can eventually implement his proper time base source (a general purpose
108 timer for example or other time source), keeping in mind that Time base
109 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
110 handled in milliseconds basis.
111 (++) Time base configuration function (HAL_InitTick ()) is called automatically
112 at the beginning of the program after reset by HAL_Init() or at any time
113 when clock is configured, by HAL_RCC_ClockConfig().
114 (++) Source of time base is configured to generate interrupts at regular
115 time intervals. Care must be taken if HAL_Delay() is called from a
116 peripheral ISR process, the Tick interrupt line must have higher priority
117 (numerically lower) than the peripheral interrupt. Otherwise the caller
118 ISR process will be blocked.
119 (++) functions affecting time base configurations are declared as __weak
120 to make override possible in case of other implementations in user file.
