mbed_official | 340:28d1f895c6fe | 8 | * This is the common part of the HAL initialization |

mbed_official | 340:28d1f895c6fe | 13 | ============================================================================== |
mbed_official | 340:28d1f895c6fe | 14 | [..] |
mbed_official | 340:28d1f895c6fe | 15 | The common HAL driver contains a set of generic and common APIs that can be |
mbed_official | 340:28d1f895c6fe | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
mbed_official | 340:28d1f895c6fe | 17 | [..] |
mbed_official | 340:28d1f895c6fe | 18 | The HAL contains two APIs categories: |
mbed_official | 340:28d1f895c6fe | 19 | (+) HAL Initialization and de-initialization functions |
mbed_official | 340:28d1f895c6fe | 20 | (+) HAL Control functions |

mbed_official | 340:28d1f895c6fe | 112 | [..] This section provides functions allowing to: |
mbed_official | 340:28d1f895c6fe | 113 | (+) Initializes the Flash interface, the NVIC allocation and initial clock |
mbed_official | 340:28d1f895c6fe | 114 | configuration. It initializes the source of time base also when timeout |
mbed_official | 340:28d1f895c6fe | 115 | is needed and the backup domain when enabled. |
mbed_official | 340:28d1f895c6fe | 116 | (+) de-Initializes common part of the HAL. |
mbed_official | 340:28d1f895c6fe | 117 | (+) Configure The time base source to have 1ms time base with a dedicated |
mbed_official | 340:28d1f895c6fe | 118 | Tick interrupt priority. |
mbed_official | 340:28d1f895c6fe | 119 | (++) Systick timer is used by default as source of time base, but user |
mbed_official | 340:28d1f895c6fe | 120 | can eventually implement his proper time base source (a general purpose |
mbed_official | 340:28d1f895c6fe | 121 | timer for example or other time source), keeping in mind that Time base |
mbed_official | 340:28d1f895c6fe | 122 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
mbed_official | 340:28d1f895c6fe | 123 | handled in milliseconds basis. |
mbed_official | 340:28d1f895c6fe | 124 | (++) Time base configuration function (HAL_InitTick ()) is called automatically |
mbed_official | 340:28d1f895c6fe | 125 | at the beginning of the program after reset by HAL_Init() or at any time |
mbed_official | 340:28d1f895c6fe | 126 | when clock is configured, by HAL_RCC_ClockConfig(). |
mbed_official | 340:28d1f895c6fe | 127 | (++) Source of time base is configured to generate interrupts at regular |
mbed_official | 340:28d1f895c6fe | 128 | time intervals. Care must be taken if HAL_Delay() is called from a |
mbed_official | 340:28d1f895c6fe | 129 | peripheral ISR process, the Tick interrupt line must have higher priority |
mbed_official | 340:28d1f895c6fe | 130 | (numerically lower) than the peripheral interrupt. Otherwise the caller |
mbed_official | 340:28d1f895c6fe | 131 | ISR process will be blocked. |
mbed_official | 340:28d1f895c6fe | 132 | (++) functions affecting time base configurations are declared as __Weak |
mbed_official | 340:28d1f895c6fe | 133 | to make override possible in case of other implementations in user file. |
