NOTES:
1. Avoid making a transition when the CM20 bit is set to 1 (oscillation stop, re-oscillation detection function enabled).
2. Wait the main clock oscillation stabilizes.
3. Switch clock after oscillation of sub clock is sufficiently stable.
4. Change bits CM17 and CM16 before changing the CM06 bit.
5. Transit in accordance with arrow.
6. The PM20 bit in the PM2 register become effective when the PLC07 bit is set to 1 (PLL on). Change the PM20 bit when the PLC07 bit is set
7. Set the CM06 bit to 1 (divide-by-8 mode) before changing back the operating mode from on-chip oscillator mode to high-speed or middle-speed
8. When the CM21 bit = 0 (on-chip oscillator turned off) and the CM05 bit = 1 (main clock turned off), the CM06 bit is fixed to 1 (divide-by-8 mode)
PLL operating mode
PLL operating mode
Set the CM20 bit to 0 (oscillation stop, re-oscillation detection function disabled) before transiting.
