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 110 ===============================================================================
bogdanm 0:9b334a45a8ff 111 [..] This section provides functions allowing to:
bogdanm 0:9b334a45a8ff 112 (+) Initializes the Flash interface the NVIC allocation and initial clock
bogdanm 0:9b334a45a8ff 113 configuration. It initializes the systick also when timeout is needed
bogdanm 0:9b334a45a8ff 114 and the backup domain when enabled.
bogdanm 0:9b334a45a8ff 115 (+) de-Initializes common part of the HAL
bogdanm 0:9b334a45a8ff 116 (+) Configure The time base source to have 1ms time base with a dedicated
bogdanm 0:9b334a45a8ff 117 Tick interrupt priority.
bogdanm 0:9b334a45a8ff 118 (++) Systick timer is used by default as source of time base, but user
bogdanm 0:9b334a45a8ff 119 can eventually implement his proper time base source (a general purpose
bogdanm 0:9b334a45a8ff 120 timer for example or other time source), keeping in mind that Time base
bogdanm 0:9b334a45a8ff 121 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
bogdanm 0:9b334a45a8ff 122 handled in milliseconds basis.
bogdanm 0:9b334a45a8ff 123 (++) Time base configuration function (HAL_InitTick ()) is called automatically
bogdanm 0:9b334a45a8ff 124 at the beginning of the program after reset by HAL_Init() or at any time
bogdanm 0:9b334a45a8ff 125 when clock is configured, by HAL_RCC_ClockConfig().
bogdanm 0:9b334a45a8ff 126 (++) Source of time base is configured to generate interrupts at regular
bogdanm 0:9b334a45a8ff 127 time intervals. Care must be taken if HAL_Delay() is called from a
bogdanm 0:9b334a45a8ff 128 peripheral ISR process, the Tick interrupt line must have higher priority
bogdanm 0:9b334a45a8ff 129 (numerically lower) than the peripheral interrupt. Otherwise the caller
bogdanm 0:9b334a45a8ff 130 ISR process will be blocked.
bogdanm 0:9b334a45a8ff 131 (++) functions affecting time base configurations are declared as __weak
bogdanm 0:9b334a45a8ff 132 to make override possible in case of other implementations in user file.
