1: Selection of the system clock by the clock control registers MR and RG is state retained at power down.
The waiting time to stabilize oscillation at return can be adjustment by setting the clock control registers MR and RG
before transition to the power down state.
2: Continuous execution of the EPOF instruction and the POF instruction is required to go into the clock operating state.
and generate the wait time until the oscillation is stabilized, and then, switch the system clock.
7: The Sub-clock (quartz-crystal oscillation) is operating except in state D.
6: When the unoperating clock is selected as the system clock, turn it on by the clock control register RG,
If the CRCK instruction is not executed, the ceramic resonator is selected as the main clock f(X
IN
).
5: When the RC oscillation circuit is used, executing the CRCK instruction is required.
Main clock (f(X
IN
)) and Sub-clock (f(X
CIN
)) are valid.
A ceramic resonator is selected as the main clock (f(X
IN
)).
4: The state after system is released from reset;
3: Continuous execution of the EPOF instruction and the POF2 instruction is required to go into the RAM back-up state.
