  [..]
   (+) Before calling any tamper or internal tamper function, you have to call first
       HAL_RTC_Init() function.
   (+) In that ine you can select to output tamper event on RTC pin.
  [..]
   This subsection provides functions allowing to
   (+) Write a data in a specified RTC Backup data register
   (+) Read a data in a specified RTC Backup data register
