SET_BIT(RCC->BDCR, RCC_BDCR_RTCEN)

Macros to enable or disable the RTC clock.

Note:

As the RTC is in the Backup domain and write access is denied to this domain after reset, you have to enable write access using HAL_PWR_EnableBkUpAccess() function before to configure the RTC (to be done once after reset).

These macros must be used after the RTC clock source was selected.

Return values:

None
