mbed_official | 181:a4cbdfbbd2f4 | 14 | [..] |
mbed_official | 181:a4cbdfbbd2f4 | 15 | The common HAL driver contains a set of generic and common APIs that can be |
mbed_official | 181:a4cbdfbbd2f4 | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
mbed_official | 181:a4cbdfbbd2f4 | 17 | [..] |
mbed_official | 181:a4cbdfbbd2f4 | 18 | The HAL contains two APIs' categories: |
mbed_official | 181:a4cbdfbbd2f4 | 19 | (+) Common HAL APIs |
mbed_official | 181:a4cbdfbbd2f4 | 20 | (+) Services HAL APIs |

mbed_official | 181:a4cbdfbbd2f4 | 105 | Tick interrupt priority. |
mbed_official | 181:a4cbdfbbd2f4 | 106 | (++) Systick timer is used by default as source of time base, but user |
mbed_official | 181:a4cbdfbbd2f4 | 107 | can eventually implement his proper time base source (a general purpose |
mbed_official | 181:a4cbdfbbd2f4 | 108 | timer for example or other time source), keeping in mind that Time base |
mbed_official | 181:a4cbdfbbd2f4 | 109 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
mbed_official | 181:a4cbdfbbd2f4 | 110 | handled in milliseconds basis. |

mbed_official | 181:a4cbdfbbd2f4 | 112 | at the beginning of the program after reset by HAL_Init() or at any time |
mbed_official | 181:a4cbdfbbd2f4 | 113 | when clock is configured, by HAL_RCC_ClockConfig(). |
mbed_official | 181:a4cbdfbbd2f4 | 114 | (++) Source of time base is configured to generate interrupts at regular |
mbed_official | 181:a4cbdfbbd2f4 | 115 | time intervals. Care must be taken if HAL_Delay() is called from a |
mbed_official | 181:a4cbdfbbd2f4 | 116 | peripheral ISR process, the Tick interrupt line must have higher priority |
mbed_official | 181:a4cbdfbbd2f4 | 117 | (numerically lower) than the peripheral interrupt. Otherwise the caller |
mbed_official | 181:a4cbdfbbd2f4 | 118 | ISR process will be blocked. |
