SIT

Interval timer one-time alarm.

SIT

Result

The ALARM flag is set after INTVAL counts and then another interval count starts.

The ALARM flag is set after one time interval.

ITFLAG

Interval timer flag. This bit is set when the configured time interval has elapsed. It can be cleared by

the user to indicate that the alarm event has been serviced.

ITEN

Reserved.

ALDAT_EN

Alarm date enable. When this bit is set, the data in the AL_DATE register is compared to the data in

the RTC DATE register. If the two values match and any other enabled RTC alarms also match, the

ALFLAG is set. If enabled, an RTC interrupt occurs.

ALDAY_EN

Alarm day enable. When this bit is set, the data in the AL_DAY register is compared to the data in the

RTC DAY register. If the two values match and any other enabled RTC alarms also match, the ALFLAG

is set. If enabled, an RTC interrupt occurs.

ALHR_EN

Alarm hour enable. When this bit is set, the data in the AL_HOUR register is compared to the data in

the RTC HOUR register. If the two values match and any other enabled RTC alarms also match, the

ALFLAG is set. If enabled, an RTC interrupt occurs.

ALMIN_EN

Alarm minute enable. When set, the data in the AL_MIN register is compared to the data in the RTC

MIN register. If the two values match and any other enabled RTC alarms also match, the ALFLAG is

set. If enabled, an RTC interrupt occurs.

ALSEC_EN

Alarm second enable. When this bit is set, the data in the AL_SEC register is compared to the data in

the RTC SEC register. If the two values match and any other enabled RTC alarms also match, the

ALFLAG is set. If enabled, an RTC interrupt occurs.
