-  * @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 Wake-up 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.
-        (@) Not available on F030x4/x6/x8 and F070x6            
-  
-    *** TimeStamp configuration ***
-    ===============================
-    [..]
-        (+) Configure the RTC_AF 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.
-  
-    *** 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 in interrupt 
-            mode using HAL_RTCEx_SetTamper_IT() function.
-  
-    *** 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.
