- and the backup domain when enabled.
- (+) de-Initializes common part of the HAL

- Tick interrupt priority.

- 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.
