LL_RTC_TIME_GetSecond() function
Get Seconds in BCD format
Syntax
Return value
Value between Min_Data=0x00 and Max_Data=0x59
Notes
if RTC shadow registers are not bypassed (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 macro __LL_RTC_CONVERT_BCD2BIN is available to convert Seconds from BCD to Binary format TR SU LL_RTC_TIME_GetSecond
