Address:
The RTC module has thirteen memory-mapped registers:
The RTC control register 1 (RTCCR1) contains the eight interrupt enable
bits for RTC interrupt functions.

This read/write bit enables the alarm flag, ALMF, to generate CPU
interrupt requests. Reset clears the ALMIE bit.
1 = ALMF enabled to generate CPU interrupt
0 = ALMF not enabled to generate CPU interrupt
