Section 11 Realtime Clock (RTC)
11.3.6 RTC Control Register 2 (RTCCR2)
RTCCR2 controls RTC periodic interrupts of week, day, hour, minute, one second, 0.5 seconds,
and 0.25 seconds. Enabling interrupts of week, day, hour, minute, one second, 0.5 seconds, and
0.25 seconds sets the corresponding flag to 1 in the RTC interrupt flag register (RTCFLG) when
an interrupt occurs. It also controls an overflow interrupt of a free running counter when RTC
operates as a free running counter.
