Section 10 Realtime Clock (RTC)
10.3.6
RTCCR2 controls RTC periodic interrupts of weeks, days, hours, minutes, and seconds. Enabling
interrupts of weeks, days, hours, minutes, and seconds sets the IRRTA flag to 1 in the interrupt
flag register 1 (IRR1) when an interrupt occurs. It also controls an overflow interrupt of a free
running counter when RTC operates as a free running counter.
