12 ##### How to use this driver #####
13 ==============================================================================
14 [..]
15 The common HAL driver contains a set of generic and common APIs that can be
16 used by the PPP peripheral drivers and the user to start using the HAL.
17 [..]
18 The HAL contains two APIs' categories:
19 (+) Common HAL APIs
20 (+) Services HAL APIs

119 [..] This section provides functions allowing to:
120 (+) Initializes the Flash interface, the NVIC allocation and initial clock
121 configuration. It initializes the source of time base also when timeout
122 is needed and the backup domain when enabled.
123 (+) de-Initializes common part of the HAL.
124 (+) Configure The time base source to have 1ms time base with a dedicated
125 Tick interrupt priority.
126 (++) Systick timer is used by default as source of time base, but user
127 can eventually implement his proper time base source (a general purpose
128 timer for example or other time source), keeping in mind that Time base
129 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
130 handled in milliseconds basis.
131 (++) Time base configuration function (HAL_InitTick ()) is called automatically
132 at the beginning of the program after reset by HAL_Init() or at any time
133 when clock is configured, by HAL_RCC_ClockConfig().
134 (++) Source of time base is configured to generate interrupts at regular
135 time intervals. Care must be taken if HAL_Delay() is called from a
136 peripheral ISR process, the Tick interrupt line must have higher priority
137 (numerically lower) than the peripheral interrupt. Otherwise the caller
138 ISR process will be blocked.
139 (++) functions affecting time base configurations are declared as __Weak
140 to make override possible in case of other implementations in user file.
