parameter must be a number between Min_Data = 1 and Max_Data = 31.This feature
can be modified afterwards using unitary function LL_RTC_ALMA_SetDay() for
ALARM A or LL_RTC_ALMB_SetDay() for ALARM B.If AlarmDateWeekDaySel set to
Weekday, this parameter can be a value of RTC_LL_EC_WEEKDAY.This feature can
be modified afterwards using unitary function LL_RTC_ALMA_SetWeekDay() for
ALARM A or LL_RTC_ALMB_SetWeekDay() for ALARM B.
