11.3.6
RTCCR2 controls RTC periodic interrupts of weeks, days, hours, minutes, and seconds. This
register is initialized to H'00 by a STBY input or the RST bit in RTCCR1, but not initialized by a
RES input. 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.
