Function description
Get time format (AM or PM notation)
Parameters
RTCx: RTC Instance
Return values
Returned: value can be one of the following values:
LL_RTC_TIME_FORMAT_AM_OR_24
LL_RTC_TIME_FORMAT_PM
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)).
