mbed_official 610:813dcc80987e 14 [..]
mbed_official 610:813dcc80987e 15 The common HAL driver contains a set of generic and common APIs that can be
mbed_official 610:813dcc80987e 16 used by the PPP peripheral drivers and the user to start using the HAL.
mbed_official 610:813dcc80987e 17 [..]
mbed_official 610:813dcc80987e 18 The HAL contains two APIs' categories:
mbed_official 610:813dcc80987e 19 (+) Common HAL APIs
mbed_official 610:813dcc80987e 20 (+) Services HAL APIs

mbed_official 610:813dcc80987e 114 ===============================================================================
mbed_official 610:813dcc80987e 115 [..] This section provides functions allowing to:
mbed_official 610:813dcc80987e 116 (+) Initialize the Flash interface the NVIC allocation and initial time base
mbed_official 610:813dcc80987e 117 clock configuration.
mbed_official 610:813dcc80987e 118 (+) De-initialize common part of the HAL.
mbed_official 610:813dcc80987e 119 (+) Configure the time base source to have 1ms time base with a dedicated
mbed_official 610:813dcc80987e 120 Tick interrupt priority.
mbed_official 610:813dcc80987e 121 (++) SysTick timer is used by default as source of time base, but user
mbed_official 610:813dcc80987e 122 can eventually implement his proper time base source (a general purpose
mbed_official 610:813dcc80987e 123 timer for example or other time source), keeping in mind that Time base
mbed_official 610:813dcc80987e 124 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
mbed_official 610:813dcc80987e 125 handled in milliseconds basis.
mbed_official 610:813dcc80987e 126 (++) Time base configuration function (HAL_InitTick ()) is called automatically
mbed_official 610:813dcc80987e 127 at the beginning of the program after reset by HAL_Init() or at any time
mbed_official 610:813dcc80987e 128 when clock is configured, by HAL_RCC_ClockConfig().
mbed_official 610:813dcc80987e 129 (++) Source of time base is configured to generate interrupts at regular
mbed_official 610:813dcc80987e 130 time intervals. Care must be taken if HAL_Delay() is called from a
mbed_official 610:813dcc80987e 131 peripheral ISR process, the Tick interrupt line must have higher priority
mbed_official 610:813dcc80987e 132 (numerically lower) than the peripheral interrupt. Otherwise the caller
mbed_official 610:813dcc80987e 133 ISR process will be blocked.
mbed_official 610:813dcc80987e 134 (++) functions affecting time base configurations are declared as __weak
mbed_official 610:813dcc80987e 135 to make override possible in case of other implementations in user file.
