11.3.7
RTCCSR selects clock source. A free running counter controls start/stop of counter operation by
the RUN bit in RTCCR1. When a clock other than φ
operates as an 8-bit free running counter. When the RTC operates as an 8-bit free running counter,
RSECDR enables counter values to be read. An interrupt can be generated by setting 1 to the
FOIE bit in RTCCR2 and enabling an overflow interrupt of the free running counter. A clock
generated by dividing the system clock by 32, 16, 8, or 4 is output in active or sleep mode. φ
output in active, sleep, subactive, subsleep, or watch mode.
