RTCCSR selects clock source. This register is initialized to H'08 by a STBY input or RES input. A
free running counter controls start/stop of counter operation by the RUN bit in RTCCR1. When a
clock other than 32.768 MHz is selected, the RTC is disabled and operates as an 8-bit free running
counter. 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 in which the system clock is divided by 32,
16, 8, or 4 is output in high-speed mode, medium-speed mode, sleep mode, subactive mode, or
subsleep mode.
