- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- 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

- ===============================================================================
- ##### Initialization and de-initialization functions #####
- ===============================================================================
- [..] This section provides functions allowing to:
- (+) Initializes the Flash interface, the NVIC allocation and initial clock
- 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
- to make override possible in case of other implementations in user file.
