64.1.1 LL_RTC_InitTypeDef
Data Fields
uint32_t HourFormat
uint32_t AsynchPrescaler
uint32_t SynchPrescaler
Field Documentation
uint32_t LL_RTC_InitTypeDef::HourFormat
Specifies the RTC Hours Format. This parameter can be a value of
RTC_LL_EC_HOURFORMATThis feature can be modified afterwards using unitary
function LL_RTC_SetHourFormat().
uint32_t LL_RTC_InitTypeDef::AsynchPrescaler
Specifies the RTC Asynchronous Predivider value. This parameter must be a number
between Min_Data = 0x00 and Max_Data = 0x7FThis feature can be modified
afterwards using unitary function LL_RTC_SetAsynchPrescaler().
uint32_t LL_RTC_InitTypeDef::SynchPrescaler
Specifies the RTC Synchronous Predivider value. This parameter must be a number
between Min_Data = 0x00 and Max_Data = 0x7FFFThis feature can be modified
afterwards using unitary function LL_RTC_SetSynchPrescaler().
64.1.2 LL_RTC_TimeTypeDef
Data Fields
uint32_t TimeFormat
uint8_t Hours
uint8_t Minutes
uint8_t Seconds
Field Documentation
uint32_t LL_RTC_TimeTypeDef::TimeFormat
Specifies the RTC AM/PM Time. This parameter can be a value of
RTC_LL_EC_TIME_FORMATThis feature can be modified afterwards using unitary
function LL_RTC_TIME_SetFormat().
uint8_t LL_RTC_TimeTypeDef::Hours
Specifies the RTC Time Hours. This parameter must be a number between Min_Data
= 0 and Max_Data = 12 if the LL_RTC_TIME_FORMAT_PM is selected. This
parameter must be a number between Min_Data = 0 and Max_Data = 23 if the
LL_RTC_TIME_FORMAT_AM_OR_24 is selected.This feature can be modified
afterwards using unitary function LL_RTC_TIME_SetHour().
uint8_t LL_RTC_TimeTypeDef::Minutes
Specifies the RTC Time Minutes. This parameter must be a number between
Min_Data = 0 and Max_Data = 59This feature can be modified afterwards using
unitary function LL_RTC_TIME_SetMinute().
uint8_t LL_RTC_TimeTypeDef::Seconds
Specifies the RTC Time Seconds. This parameter must be a number between
