Hi, I'm using the MCU STM32l476, and I have a problem with RTC. The RTC works only if the board is turned on. When the board is turned off or it's sent a command to the MCU go to shutdown mode, the RTC is reset to zero values.

According to the datasheet, there is shutdown mode with and without RTC, so I believe it's a problem of configuration. Can be some parameter of configuration that is missing? How to configure the shutdown mode with RTC?Thanks!
