| [..] |
| 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: |
| (+) Common HAL APIs |
| (+) Services HAL APIs |

| =============================================================================== |
| [..] This section provides functions allowing to: |
| (+) Initialize the Flash interface the NVIC allocation and initial time base |
| clock configuration. |
| (+) De-initialize 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. |
