mbed_official | 237:f3da66175598 | 14 | [..] |
mbed_official | 237:f3da66175598 | 15 | The common HAL driver contains a set of generic and common APIs that can be |
mbed_official | 237:f3da66175598 | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
mbed_official | 237:f3da66175598 | 17 | [..] |
mbed_official | 237:f3da66175598 | 18 | The HAL contains two APIs categories: |
mbed_official | 237:f3da66175598 | 19 | (+) HAL Initialization and de-initialization functions |
mbed_official | 237:f3da66175598 | 20 | (+) HAL Control functions |

mbed_official | 237:f3da66175598 | 101 | (+) Initializes the Flash interface the NVIC allocation and initial clock |
mbed_official | 237:f3da66175598 | 102 | configuration. It initializes the systick also when timeout is needed |
mbed_official | 237:f3da66175598 | 103 | and the backup domain when enabled. |
mbed_official | 237:f3da66175598 | 104 | (+) de-Initializes common part of the HAL |
mbed_official | 237:f3da66175598 | 105 | (+) Configure The time base source to have 1ms time base with a dedicated |
mbed_official | 237:f3da66175598 | 106 | Tick interrupt priority. |
mbed_official | 237:f3da66175598 | 107 | (++) Systick timer is used by default as source of time base, but user |
mbed_official | 237:f3da66175598 | 108 | can eventually implement his proper time base source (a general purpose |
mbed_official | 237:f3da66175598 | 109 | timer for example or other time source), keeping in mind that Time base |
mbed_official | 237:f3da66175598 | 110 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
mbed_official | 237:f3da66175598 | 111 | handled in milliseconds basis. |

mbed_official | 237:f3da66175598 | 114 | when clock is configured, by HAL_RCC_ClockConfig(). |
mbed_official | 237:f3da66175598 | 115 | (++) Source of time base is configured to generate interrupts at regular |
mbed_official | 237:f3da66175598 | 116 | time intervals. Care must be taken if HAL_Delay() is called from a |
mbed_official | 237:f3da66175598 | 117 | peripheral ISR process, the Tick interrupt line must have higher priority |
mbed_official | 237:f3da66175598 | 118 | (numerically lower) than the peripheral interrupt. Otherwise the caller |
mbed_official | 237:f3da66175598 | 119 | ISR process will be blocked. |
