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

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.
