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 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.
