==============================================================================
                ##### 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_RTC_SetWakeUpTimer()
      function. You can also configure the RTC Wakeup timer in interrupt mode 
      using the HAL_RTC_SetWakeUpTimer_IT() function.
  (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer() 
      function.

*** TimeStamp configuration ***
===============================
[..]
  (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
      You can also configure the RTC TimeStamp with interrupt mode using the
      HAL_RTC_SetTimeStamp_IT() function.
  (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
      function.

*** Internal TimeStamp configuration ***
===============================
[..]
  (+) Enables the RTC internal TimeStamp using the HAL_RTC_SetInternalTimeStamp() function.
  (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_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_RTC_SetTamper() function. You can configure RTC Tamper
      with interrupt mode using HAL_RTC_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_RTC_BKUPWrite()
      function.  
  (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
      function.
