bogdanm 0:9b334a45a8ff 14 [..]
bogdanm 0:9b334a45a8ff 15 The common HAL driver contains a set of generic and common APIs that can be
bogdanm 0:9b334a45a8ff 16 used by the PPP peripheral drivers and the user to start using the HAL.
bogdanm 0:9b334a45a8ff 17 [..]
bogdanm 0:9b334a45a8ff 18 The HAL contains two APIs categories:
bogdanm 0:9b334a45a8ff 19 (+) Common HAL APIs
bogdanm 0:9b334a45a8ff 20 (+) Services HAL APIs

bogdanm 0:9b334a45a8ff 115 ===============================================================================
bogdanm 0:9b334a45a8ff 116 [..] This section provides functions allowing to:
bogdanm 0:9b334a45a8ff 117 (+) Initializes the Flash interface, the NVIC allocation and initial clock
bogdanm 0:9b334a45a8ff 118 configuration. It initializes the source of time base also when timeout
bogdanm 0:9b334a45a8ff 119 is needed and the backup domain when enabled.
bogdanm 0:9b334a45a8ff 120 (+) de-Initializes common part of the HAL.
bogdanm 0:9b334a45a8ff 121 (+) Configure The time base source to have 1ms time base with a dedicated
bogdanm 0:9b334a45a8ff 122 Tick interrupt priority.
bogdanm 0:9b334a45a8ff 123 (++) Systick timer is used by default as source of time base, but user
bogdanm 0:9b334a45a8ff 124 can eventually implement his proper time base source (a general purpose
bogdanm 0:9b334a45a8ff 125 timer for example or other time source), keeping in mind that Time base
bogdanm 0:9b334a45a8ff 126 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
bogdanm 0:9b334a45a8ff 127 handled in milliseconds basis.
bogdanm 0:9b334a45a8ff 128 (++) Time base configuration function (HAL_InitTick ()) is called automatically
bogdanm 0:9b334a45a8ff 129 at the beginning of the program after reset by HAL_Init() or at any time
bogdanm 0:9b334a45a8ff 130 when clock is configured, by HAL_RCC_ClockConfig().
bogdanm 0:9b334a45a8ff 131 (++) Source of time base is configured to generate interrupts at regular
bogdanm 0:9b334a45a8ff 132 time intervals. Care must be taken if HAL_Delay() is called from a
bogdanm 0:9b334a45a8ff 133 peripheral ISR process, the Tick interrupt line must have higher priority
bogdanm 0:9b334a45a8ff 134 (numerically lower) than the peripheral interrupt. Otherwise the caller
bogdanm 0:9b334a45a8ff 135 ISR process will be blocked.
bogdanm 0:9b334a45a8ff 136 (++) functions affecting time base configurations are declared as __weak
bogdanm 0:9b334a45a8ff 137 to make override possible in case of other implementations in user file.
