Notes 1: Continuous execution of the EPOF instruction and the POF instruction is required to go into the clock operating state.
Continuous execution of the EPOF instruction and the POF2 instruction is required to go into the RAM back-up state.
2: Through the ceramic resonator is operating, the on-chip oscillator clock is selected as the operation source clock.
3: The oscillator clock corresponding to each instruction is selected as the operation source clock, and the on-chip oscillator is stopped.
4: The main clock (f(XIN) or f(RING)) or sub-clock (f(XCIN)) is selected for operation source clock by the bit 0 of clock control register MR.
5: The sub-clock (quartz-crystal oscillation) is operating except in state F.
