+ ******************************************************************************
+ * @file stm32l1xx_hal_rtc_ex.c
+ * @author MCD Application Team
+ * @version V1.0.0
+ * @date 5-September-2014
+ * @brief Extended RTC HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Real Time Clock (RTC) Extension peripheral:
+ * + RTC Time Stamp functions
+ * + RTC Tamper functions
+ * + RTC Wake-up functions
+ * + Extension Control functions
+ * + Extension 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.
+
+ *** TimeStamp configuration ***
+ ===============================
+ [..]
+ (+) Configure the RTC_AFx trigger and 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.
+ (+) The TIMESTAMP alternate function can be mapped to RTC_AF1 (PC13).
+
+ *** 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, 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 TAMPER1 alternate function can be mapped to RTC_AF1 (PC13).
+
+ *** 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.
