+  ==============================================================================
+               ##### RTC and Backup Domain Operating Condition #####
+  ==============================================================================
+  [..] The real-time clock (RTC) and the RTC backup registers can be powered
+       from the VBAT voltage when the main VDD supply is powered off.
+       To retain the content of the RTC backup registers and supply the RTC when
+       VDD is turned off, VBAT pin can be connected to an optional standby
+       voltage supplied by a battery or by another source.
+
+  [..] To allow the RTC operating even when the main digital supply (VDD) is turned
+       off, the VBAT pin powers the following blocks:
+    (#) The RTC
+    (#) The LSE oscillator
+    (#) PC13 to PC15 I/Os, plus PA0 and PE6 I/Os (when available)
+
+  [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
+       the following pins are available:
+    (#) PC14 and PC15 can be used as either GPIO or LSE pins
+    (#) PC13 can be used as a GPIO or as the RTC_AF1 pin
+    (#) PA0 can be used as a GPIO or as the RTC_AF2 pin
+    (#) PE6 can be used as a GPIO or as the RTC_AF3 pin
+
+  [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT
+       because VDD is not present), the following pins are available:
+    (#) PC14 and PC15 can be used as LSE pins only
+    (#) PC13 can be used as the RTC_AF1 pin
+    (#) PA0 can be used as the RTC_AF2 pin
+    (#) PE6 can be used as the RTC_AF3 pin
+
+                   ##### Backup Domain Reset #####
+  ==================================================================
+  [..] The backup domain reset sets all RTC registers and the RCC_BDCR register
+       to their reset values.
+  [..] A backup domain reset is generated when one of the following events occurs:
+    (#) Software reset, triggered by setting the BDRST bit in the
+        RCC Backup domain control register (RCC_BDCR).
+    (#) VDD or VBAT power on, if both supplies have previously been powered off.
+    (#) Tamper detection event resets all data backup registers.
+
+                   ##### Backup Domain Access #####
+  ==================================================================
+  [..] After reset, the backup domain (RTC registers, RTC backup data registers
+       is protected against possible unwanted write accesses.
+  [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
+    (+) Enable the Power Controller (PWR) APB1 interface clock using the
+        __HAL_RCC_PWR_CLK_ENABLE() macro.
+    (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
+    (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() macro.
+    (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() macro.
+
+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    (+) Enable the RTC domain access (see description in the section above).
+    (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
+        format using the HAL_RTC_Init() function.
+
+  *** Time and Date configuration ***
+  ===================================
+  [..]
+    (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
+        and HAL_RTC_SetDate() functions.
+    (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate()
+        functions.
+    (+) To manage the RTC summer or winter time change, use the following
+        functions:
+        (++) HAL_RTC_DST_Add1Hour() or HAL_RTC_DST_Sub1Hour to add or subtract
+             1 hour from the calendar time.
+        (++) HAL_RTC_DST_SetStoreOperation() or HAL_RTC_DST_ClearStoreOperation
+             to memorize whether the time change has been performed or not.
+
+  *** Alarm configuration ***
+  ===========================
+  [..]
+    (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
+        You can also configure the RTC Alarm with interrupt mode using the
+        HAL_RTC_SetAlarm_IT() function.
+    (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
+
+                  ##### RTC and low power modes #####
+  ==================================================================
+  [..] The MCU can be woken up from a low power mode by an RTC alternate
+       function.
+  [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
+       RTC wakeup, RTC tamper event detection and RTC timestamp event detection.
+       These RTC alternate functions can wake up the system from the Stop and
+       Standby low power modes.
+  [..] The system can also wake up from low power modes without depending
+       on an external interrupt (Auto-wakeup mode), by using the RTC alarm
+       or the RTC wakeup events.
+  [..] The RTC provides a programmable time base for waking up from the
+       Stop or Standby mode at regular intervals.
+       Wakeup from STOP and STANDBY modes is possible only when the RTC clock
+       source is LSE or LSI.
+
+  *** Callback registration ***
+  =============================================
+  [..]
+  The compilation define  USE_HAL_RTC_REGISTER_CALLBACKS when set to 1
+  allows the user to configure dynamically the driver callbacks.
+  Use Function HAL_RTC_RegisterCallback() to register an interrupt callback.
+  [..]
+  Function HAL_RTC_RegisterCallback() allows to register following callbacks:
+    (+) AlarmAEventCallback          : RTC Alarm A Event callback.
+    (+) AlarmBEventCallback          : RTC Alarm B Event callback.
+    (+) TimeStampEventCallback       : RTC Timestamp Event callback.
+    (+) WakeUpTimerEventCallback     : RTC WakeUpTimer Event callback.
+    (+) Tamper1EventCallback         : RTC Tamper 1 Event callback.
+    (+) Tamper2EventCallback         : RTC Tamper 2 Event callback.
+    (+) Tamper3EventCallback         : RTC Tamper 3 Event callback.
+    (+) MspInitCallback              : RTC MspInit callback.
+    (+) MspDeInitCallback            : RTC MspDeInit callback.
+  [..]
+  This function takes as parameters the HAL peripheral handle, the Callback ID
+  and a pointer to the user callback function.
+  [..]
+  Use function HAL_RTC_UnRegisterCallback() to reset a callback to the default
+  weak function.
+  HAL_RTC_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+  and the Callback ID.
+  This function allows to reset following callbacks:
+    (+) AlarmAEventCallback          : RTC Alarm A Event callback.
+    (+) AlarmBEventCallback          : RTC Alarm B Event callback.
+    (+) TimeStampEventCallback       : RTC Timestamp Event callback.
+    (+) WakeUpTimerEventCallback     : RTC WakeUpTimer Event callback.
+    (+) Tamper1EventCallback         : RTC Tamper 1 Event callback.
+    (+) Tamper2EventCallback         : RTC Tamper 2 Event callback.
+    (+) Tamper3EventCallback         : RTC Tamper 3 Event callback.
+    (+) MspInitCallback              : RTC MspInit callback.
+    (+) MspDeInitCallback            : RTC MspDeInit callback.
+  [..]
+  By default, after the HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET,
+  all callbacks are set to the corresponding weak functions:
+  examples AlarmAEventCallback(), WakeUpTimerEventCallback().
+  Exception done for MspInit() and MspDeInit() callbacks that are reset to the
+  legacy weak function in the HAL_RTC_Init()/HAL_RTC_DeInit() only
+  when these callbacks are null (not registered beforehand).
+  If not, MspInit() or MspDeInit() are not null, HAL_RTC_Init()/HAL_RTC_DeInit()
+  keep and use the user MspInit()/MspDeInit() callbacks (registered beforehand).
+  [..]
+  Callbacks can be registered/unregistered in HAL_RTC_STATE_READY state only.
+  Exception done MspInit()/MspDeInit() that can be registered/unregistered
+  in HAL_RTC_STATE_READY or HAL_RTC_STATE_RESET state.
+  Thus registered (user) MspInit()/MspDeInit() callbacks can be used during the
+  Init/DeInit.
+  In that case first register the MspInit()/MspDeInit() user callbacks
+  using HAL_RTC_RegisterCallback() before calling HAL_RTC_DeInit()
+  or HAL_RTC_Init() functions.
+  [..]
+  When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or
+  not defined, the callback registration feature is not available and all
+  callbacks are set to the corresponding weak functions.

+ ===============================================================================
+              ##### Initialization and de-initialization functions #####
+ ===============================================================================
+   [..] This section provides functions allowing to initialize and configure the
+         RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
+         RTC registers Write protection, enter and exit the RTC initialization mode,
+         RTC registers synchronization check and reference clock detection enable.
+         (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
+             It is split into 2 programmable prescalers to minimize power consumption.
+             (++) A 7-bit asynchronous prescaler and a 15-bit synchronous prescaler.
+             (++) When both prescalers are used, it is recommended to configure the
+                 asynchronous prescaler to a high value to minimize power consumption.
+         (#) All RTC registers are Write protected. Writing to the RTC registers
+             is enabled by writing a key into the Write Protection register, RTC_WPR.
+         (#) To configure the RTC Calendar, user application should enter
+             initialization mode. In this mode, the calendar counter is stopped
+             and its value can be updated. When the initialization sequence is
+             complete, the calendar restarts counting after 4 RTCCLK cycles.
+         (#) To read the calendar through the shadow registers after Calendar
+             initialization, calendar update or after wakeup from low power modes
+             the software must first clear the RSF flag. The software must then
+             wait until it is set again before reading the calendar, which means
+             that the calendar registers have been correctly copied into the
+             RTC_TR and RTC_DR shadow registers. The HAL_RTC_WaitForSynchro() function
+             implements the above software sequence (RSF clear and RSF check).

+  @verbatim
+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    (+) Enable the RTC domain access.
+    (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
+        format using the HAL_RTC_Init() function.
+
+  *** RTC Wakeup configuration ***
+  ================================
+  [..]
+    (+) To configure the RTC Wakeup Clock source and Counter use the
+        HAL_RTCEx_SetWakeUpTimer() function.
+        You can also configure the RTC Wakeup timer in interrupt mode using the
+        HAL_RTCEx_SetWakeUpTimer_IT() function.
+    (+) To read the RTC Wakeup Counter register, use the HAL_RTCEx_GetWakeUpTimer()
+        function.
+
+  *** Timestamp configuration ***
+  ===============================
+  [..]
+    (+) To configure the RTC Timestamp use the HAL_RTCEx_SetTimeStamp() function.
+        You can also configure the RTC Timestamp with interrupt mode using the
+        HAL_RTCEx_SetTimeStamp_IT() function.
+    (+) To read the RTC Timestamp Time and Date register, use the
+        HAL_RTCEx_GetTimeStamp() function.
+    (+) The Timestamp alternate function is mapped to RTC_AF1 (PC13).
+
+  *** Tamper configuration ***
+  ============================
+  [..]
+    (+) To Enable the RTC Tamper and configure the Tamper filter count, trigger
+        Edge or Level according to the Tamper filter value (if equal to 0 Edge
+        else Level), sampling frequency, NoErase, MaskFlag, precharge or
+        discharge and Pull-UP use the HAL_RTCEx_SetTamper() function.
+        You can configure RTC Tamper in interrupt mode using HAL_RTCEx_SetTamper_IT()
+        function.
+    (+) The default configuration of the Tamper erases the backup registers.
+        To avoid this, enable the NoErase field on the RTC_TAMPCR register.
+    (+) The TAMPER1 alternate function is mapped to RTC_AF1 (PC13).
+    (+) The TAMPER2 alternate function is mapped to RTC_AF2 (PA0).
+    (+) The TAMPER3 alternate function is mapped to RTC_AF3 (PE6).
+
+  *** Backup Data Registers configuration ***
+  ===========================================
+  [..]
+    (+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite()
+        function.
+    (+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead()
+        function.
+
+  *** Smooth Digital Calibration configuration ***
+  ================================================
+  [..]
+    (+) RTC frequency can be digitally calibrated with a resolution of about
+        0.954 ppm with a range from -487.1 ppm to +488.5 ppm.
+        The correction of the frequency is performed using a series of small
+        adjustments (adding and/or subtracting individual RTCCLK pulses).
+    (+) The smooth digital calibration is performed during a cycle of about 2^20
+        RTCCLK pulses (or 32 seconds) when the input frequency is 32,768 Hz.
+        This cycle is maintained by a 20-bit counter clocked by RTCCLK.
+    (+) The smooth calibration register (RTC_CALR) specifies the number of RTCCLK
+        clock cycles to be masked during the 32-second cycle.
+    (+) The RTC Smooth Digital Calibration value and the corresponding calibration
+        cycle period (32s, 16s, or 8s) can be calibrated using the
+        HAL_RTCEx_SetSmoothCalib() function.
+
+  *** Outputs configuration ***
+  =============================
+  [..] The RTC has 2 different outputs:
+    (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
+        and WaKeUp signals.
+        To output the selected RTC signal, use the HAL_RTC_Init() function.
+    (+) RTC_CALIB: this output is 512Hz signal or 1Hz.
+        To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
+    (+) Two pins can be used as RTC_ALARM or RTC_CALIB output, selected through
+        bit OUT_RMP of the RTC_OR register:
+        - (PC13, PB14) for STM32L05x/6x/7x/8x
+        - (PA2, PB14) for STM32L03x/4x
+    (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
+        automatically configured in output alternate function.
