LL RTC Generic Driver
UM1940
1070/1371
DocID028236 Rev 2
Function description
Get Hours in BCD format.
Parameters
RTCx: RTC Instance
Return values
Value: between Min_Data=0x01 and Max_Data=0x12 or
between Min_Data=0x00 and Max_Data=0x23
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 macro __LL_RTC_CONVERT_BCD2BIN is available
to convert hour from BCD to Binary format

TR HT LL_RTC_TIME_GetHour
TR HU LL_RTC_TIME_GetHour
LL_RTC_TIME_SetMinute
Function name
__STATIC_INLINE void LL_RTC_TIME_SetMinute
(RTC_TypeDef * RTCx, uint32_t Minutes)
Function description
Set Minutes in BCD format.
Parameters
RTCx: RTC Instance
Minutes: Value between Min_Data=0x00 and
Max_Data=0x59
Return values
None:
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)
helper macro __LL_RTC_CONVERT_BIN2BCD is available
to convert Minutes from binary to BCD format
