RTC Interrupt Enable Register (RTC_IER)
The RTC_IER register enables/disables the various real-time clock interrupts. Masking an interrupt bit has
no effect on its corresponding status bit.
7
2HZ
2 Hz interrupt flag. Indicates an interrupt has occurred. If enabled, this bit is set every half a second.
0 No interrupt has occurred
1 A 2 Hz interrupt has occurred
6
Reserved, must be cleared.
5
HR
Hour interrupt flag. If enabled, this bit is set on every increment of the hour counter in the RTC_HOURMIN register.
0 No interrupt has occurred
1 An hour interrupt has occurred
4
1HZ
1 Hz interrupt flag. If enabled, this bit is set on every increment of the second counter of the RTC_SECONDS
register.
0 No interrupt has occurred
1 A 1 Hz interrupt has occurred
3
DAY
Day interrupt flag. If enabled, this bit is set on every increment of the day counter in the RTC_DAYS register.
0 No interrupt has occurred
1 A day interrupt has occurred
2
ALM
Alarm interrupt flag. Indicates the real-time clock matches the value in the alarm registers. The alarm reoccurs
every 65,536 days. For a single alarm, clear the interrupt enable for this bit in the interrupt service routine.
0 No interrupt has occurred
1 An alarm interrupt has occurred
1
MIN
If enabled, this bit is set on every increment of the minute counter in the RTC_HOURMIN register.
0 No interrupt has occurred
1 A minute interrupt has occurred
0
SW
Stopwatch flag. Indicates that the stopwatch countdown timed out.
0 The stopwatch did not timeout
1 The stopwatch timed out
