SNPDIF
Snoop Detect Interrupt Flag
When tamper pin transition event is detected, this bit is set to 1 and an interrupt is
generated if Snoop Detection Interrupt enabled SNPDIEN (RTC_INTEN[2]) is set to1. Chip
will be waken up from Power-down mode if spare register snooper detect interrupt is
enabled.
0 = No snoop event is detected.
1 = Snoop event is detected.
Note:
Write 1 to clear this bit.
[1]
TICKIF
RTC Time Tick Interrupt Flag
When RTC time tick happened, this bit will be set to 1 and an interrupt will be generated if
RTC Tick Interrupt enabled TICKIEN (RTC_INTEN[1]) is set to 1. Chip will also be waken
up if RTC Tick Interrupt is enabled and this bit is set to 1 when chip is running at Power-
down mode.
0 = Tick condition does not occur.
1 = Tick condition occur.
Note:
Write 1 to clear to clear this bit.
[0]
ALMIF
RTC Alarm Interrupt Flag
When RTC time counters RTC_TIME and RTC_CAL match the alarm setting time
registers RTC_TALM and RTC_CALM, this bit will be set to 1 and an interrupt will be
generated if RTC Alarm Interrupt enabled ALMIEN (RTC_INTEN[0]) is set to 1. Chip will
be waken up if RTC Alarm Interrupt is enabled when chip is at Power-down mode.
0 = Alarm condition is not matched.
1 = Alarm condition is matched.
Note:
Write 1 to clear this bit.
