+ * @brief Extended RTC HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Real Time Clock (RTC) Extended peripheral:
+ * + RTC Time Stamp functions
+ * + RTC Tamper functions
+ * + RTC Wake-up functions
+ * + Extended Control functions
+ * + Extended RTC features functions
+ *
+ @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 with interrupt mode
+ using the HAL_RTCEx_SetWakeUpTimer_IT() function.
+ (+) To read the RTC WakeUp Counter register, use the HAL_RTCEx_GetWakeUpTimer()
+ 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 (PC13, PB2) managed on
+ the RTC_OR register.
+ (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
+ automatically configured in output alternate function.
+
+ *** Smooth digital Calibration configuration ***
+ ================================================
+ [..]
+ (+) Configure the RTC Original Digital Calibration Value and the corresponding
+ calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
+ function.
+
+ *** TimeStamp configuration ***
+ ===============================
+ [..]
+ (+) Enable the RTC TimeStamp using 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.
+
+ *** Internal TimeStamp configuration ***
+ ===============================
+ [..]
+ (+) Enable the RTC internal TimeStamp using the HAL_RTCEx_SetInternalTimeStamp() function.
+ User has to check internal timestamp occurrence using __HAL_RTC_INTERNAL_TIMESTAMP_GET_FLAG.
+ (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp()
+ function.
+
+ *** Tamper configuration ***
+ ============================
+ [..]
+ (+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge
+ or Level according to the Tamper filter (if equal to 0 Edge else Level)
+ value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
+ Pull-UP using the HAL_RTCEx_SetTamper() function. You can configure RTC Tamper
+ with interrupt mode using HAL_RTCEx_SetTamper_IT() function.
+ (+) The default configuration of the Tamper erases the backup registers. To avoid
+ erase, enable the NoErase field on the RTC_TAMPCR register.
+
+ *** 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.
