mbed_official 87:085cde657901 14 [..]
mbed_official 87:085cde657901 15 The common HAL driver contains a set of generic and common APIs that can be
mbed_official 87:085cde657901 16 used by the PPP peripheral drivers and the user to start using the HAL.
mbed_official 87:085cde657901 17 [..]
mbed_official 226:b062af740e40 18 The HAL contains two APIs' categories:
mbed_official 87:085cde657901 19 (+) Common HAL APIs
mbed_official 87:085cde657901 20 (+) Services HAL APIs

mbed_official 87:085cde657901 111 ===============================================================================
mbed_official 87:085cde657901 112 [..] This section provides functions allowing to:
mbed_official 87:085cde657901 113 (+) Initializes the Flash interface the NVIC allocation and initial clock
mbed_official 87:085cde657901 114 configuration. It initializes the systick also when timeout is needed
mbed_official 87:085cde657901 115 and the backup domain when enabled.
mbed_official 87:085cde657901 116 (+) de-Initializes common part of the HAL
mbed_official 226:b062af740e40 117 (+) Configure The time base source to have 1ms time base with a dedicated
mbed_official 226:b062af740e40 118 Tick interrupt priority.
mbed_official 226:b062af740e40 119 (++) Systick timer is used by default as source of time base, but user
mbed_official 226:b062af740e40 120 can eventually implement his proper time base source (a general purpose
mbed_official 226:b062af740e40 121 timer for example or other time source), keeping in mind that Time base
mbed_official 226:b062af740e40 122 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
mbed_official 226:b062af740e40 123 handled in milliseconds basis.
mbed_official 226:b062af740e40 124 (++) Time base configuration function (HAL_InitTick ()) is called automatically
mbed_official 226:b062af740e40 125 at the beginning of the program after reset by HAL_Init() or at any time
mbed_official 226:b062af740e40 126 when clock is configured, by HAL_RCC_ClockConfig().
mbed_official 226:b062af740e40 127 (++) Source of time base is configured to generate interrupts at regular
mbed_official 226:b062af740e40 128 time intervals. Care must be taken if HAL_Delay() is called from a
mbed_official 226:b062af740e40 129 peripheral ISR process, the Tick interrupt line must have higher priority
mbed_official 226:b062af740e40 130 (numerically lower) than the peripheral interrupt. Otherwise the caller
mbed_official 226:b062af740e40 131 ISR process will be blocked.
mbed_official 226:b062af740e40 132 (++) functions affecting time base configurations are declared as __weak
mbed_official 226:b062af740e40 133 to make override possible in case of other implementations in user file.
