Notes
Bit is write-protected. LL_RTC_DisableWriteProtection
function should be called before.
It can be written in initialization mode only
(LL_RTC_EnableInitMode function)

Function name

0x00HHMMSS).
Notes
if shadow mode is disabled (BYPSHAD=0), need to check if
RSF flag is set before reading this bit
Read either RTC_SSR or RTC_TR locks the values in the
higher-order calendar shadow registers until RTC_DR is read
(LL_RTC_ReadReg(RTC, DR)).
helper macros __LL_RTC_GET_HOUR,
__LL_RTC_GET_MINUTE and __LL_RTC_GET_SECOND
are available to get independently each parameter.
