Real Time Clock (RTC)
12.10.3 RTC Control Register 1 (RTCCR1)
Data Sheet
234
Address:
The RTC control register 1 (RTCCR1) contains the eight interrupt enable
bits for RTC interrupt functions.
ALMIE — Alarm Interrupt Enable
CHRIE — Chronograph Interrupt Enable
DAYIE — Day Interrupt Enable
HRIE — Hour Interrupt Enable
MINIE — Minute Interrupt Enable
Reset:
Read:
Write:
This read/write bit enables the alarm flag, ALMF, to generate CPU
interrupt requests. Reset clears the ALMIE bit.
This read/write bit enables the chronograph flag, CHRF, to generate
CPU interrupt requests. Reset clears the CHRIE bit.
This read/write bit enables the day flag, DAYF, to generate CPU
interrupt requests. Reset clears the DAYIE bit.
This read/write bit enables the hour flag, HRF, to generate CPU
interrupt requests. Reset clears the HRIE bit.
This read/write bit enables the minute flag, MINF, to generate CPU
interrupt requests. Reset clears the MINIE bit.
1 = ALMF enabled to generate CPU interrupt
0 = ALMF not enabled to generate CPU interrupt
1 = CHRF enabled to generate CPU interrupt
0 = CHRF not enabled to generate CPU interrupt
1 = DAYF enabled to generate CPU interrupt
0 = DAYF not enabled to generate CPU interrupt
1 = HRF enabled to generate CPU interrupt
0 = HRF not enabled to generate CPU interrupt
1 = MINF enabled to generate CPU interrupt
0 = MINF not enabled to generate CPU interrupt
