- @verbatim
- ===============================================================================
- ##### RTC 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.
-
- ##### 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 and backup SRAM) is protected against possible unwanted write
- accesses.
-
- [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
- (#) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_RTC for
- PeriphClockSelection and select RTCClockSelection (LSE, LSI or HSEdiv32)
- (#) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() macro.
-
- ##### How to use RTC 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.
-
- *** 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 time stamp 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_RTC_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Function @ref HAL_RTC_RegisterCallback() to register an interrupt callback.
-
- Function @ref 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 @ref HAL_RTC_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref 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 @ref HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET,
- all callbacks are set to the corresponding weak functions :
- examples @ref AlarmAEventCallback(), @ref WakeUpTimerEventCallback().
- Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function
- in the @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() only when these callbacks are null
- (not registered beforehand).
- If not, MspInit or MspDeInit are not null, @ref HAL_RTC_Init()/@ref 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/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_RTC_RegisterCallback() before calling @ref HAL_RTC_DeInit()
- or @ref HAL_RTC_Init() function.
-
- 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
+ ===============================================================================
+ ##### RTC 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.
+
+ ##### 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 and backup SRAM) is protected against possible unwanted write
+ accesses.
+
+ [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
+ (#) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_RTC for
+ PeriphClockSelection and select RTCClockSelection (LSE, LSI or HSEdiv32)
+ (#) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() macro.
+
+ ##### How to use RTC 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.
+
+ *** 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 time stamp 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_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/DeInit 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() function.
+
+ 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).
