OUTPUT POLARITY PIN
LL_RTC_OUTPUTPOLARITY_PIN_HIGH
Pin is high when ALRAF/ALRBF/WUTF is
asserted (depending on OSEL)
LL_RTC_OUTPUTPOLARITY_PIN_LOW
Pin is low when ALRAF/ALRBF/WUTF is
asserted (depending on OSEL)
TAMPER1 mapping
LL_RTC_TamperPin_Default
Use RTC_AF1 as TAMPER1
LL_RTC_TamperPin_Pos1
Use RTC_AF2 as TAMPER1
TAMPER
LL_RTC_TAMPER_1
RTC_TAMP1 input detection
TAMPER ACTIVE LEVEL
LL_RTC_TAMPER_ACTIVELEVEL_TAMP1
RTC_TAMP1 input falling edge (if
TAMPFLT = 00) or staying high (if
TAMPFLT != 00) triggers a tamper detection
event
TAMPER MASK
LL_RTC_TAMPER_MASK_TAMPER1
Tamper 1 event generates a trigger event.
TAMP1F is masked and internally cleared by
hardware.The backup registers are not erased
TAMPER NO ERASE
LL_RTC_TAMPER_NOERASE_TAMPER1
Tamper 1 event does not erase the backup
registers.
TIMESTAMP EDGE
LL_RTC_TIMESTAMP_EDGE_RISING
RTC_TS input rising edge generates a time-
stamp event
LL_RTC_TIMESTAMP_EDGE_FALLING
RTC_TS input falling edge generates a time-
stamp even
TIME FORMAT
LL_RTC_TIME_FORMAT_AM_OR_24
AM or 24-hour format

TIMESTAMP mapping
LL_RTC_TimeStampPin_Default
Use RTC_AF1 as TIMESTAMP
LL_RTC_TimeStampPin_Pos1
Use RTC_AF2 as TIMESTAMP
