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.
