Table 8.8 Allowed Transition and Setting
-: Cannot transit
NOTES:
1. Avoid making a transition when the CM20 bit is set to 1 (oscillation
2. On-chip oscillator clock oscillates and stops in low-speed mode. In this
3. PLL operating mode can only be entered from and changed to high-speed
4. Set the CM06 bit to 1 (divide-by-8 mode) before transiting from on-chip
5. When exiting stop mode, the CM06 bit is set to 1 (divide-by-8 mode).
6. If the CM05 bit is set to 1 (main clock stop), then the CM06 bit is set to 1
7. A transition can be made only when sub clock is oscillating.
8. State transitions within the same mode (divide-by-n values changed or sub
