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 99 [..] This section provides functions allowing to:
mbed_official 181:a4cbdfbbd2f4 100 (+) Initializes the Flash interface, the NVIC allocation and initial clock
mbed_official 181:a4cbdfbbd2f4 101 configuration. It initializes the source of time base also when timeout
mbed_official 181:a4cbdfbbd2f4 102 is needed and the backup domain when enabled.
mbed_official 181:a4cbdfbbd2f4 103 (+) de-Initializes common part of the HAL.
mbed_official 181:a4cbdfbbd2f4 104 (+) Configure The time base source to have 1ms time base with a dedicated
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 111 (++) Time base configuration function (HAL_InitTick ()) is called automatically
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.
mbed_official 181:a4cbdfbbd2f4 119 (++) functions affecting time base configurations are declared as __Weak
mbed_official 181:a4cbdfbbd2f4 120 to make override possible in case of other implementations in user file.
