However, the selected contents (CMCK, CRCK, CYCK instruction execution state) of f(XIN) oscillation circuit is retained.
5: System returns to state A certainly when returning from the RAM back-up mode.
4: Continuous execution of the EPOF instruction and the POF instruction is required to go into the RAM back-up state.
3: Generate the wait time by software until the oscillation is stabilized, and then, switch the system clock.
MR1 cannot be cleared to “ 0”
when the oscillation circuit is not selected.
Surely, select the f(XIN) oscillation circuit by executing the CMCK, CRCK or CYCK instruction before clearing MR1 to “ 0” .
The start/stop of oscillation and the operation source is switched by register MR.
instruction starts oscillatng (the start of oscillation and the operation source clock is not switched by these instructions).
