+ ==============================================================================
+ ##### 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 PC12 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
+ (#) PC12 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
+ (#) PC12 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 and 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 ***
+ =============================================
+ [..]
+ 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.
+ This is the recommended configuration in order to optimize memory/code
+ consumption footprint/performances.
+ [..]
+ 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.
+
+ (*) value not applicable to all devices.
+ [..]
+ 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.
+
+ (*) value not applicable to all devices.
+ [..]
+ 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(), TimeStampEventCallback().
+ 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 for MspInit() and 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.

+ ===============================================================================
+ ##### 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).
