1. Avoid making a transition when the CM20 bit is set to 1 (oscillation stop, re-oscillation detection function enabled).
2. Wait for the main clock oscillation stabilization time before switching over.
3. Switch clock after oscillation of sub-clock is sufficiently stable.
4. Change bits CM17 and CM16 before changing the CM06 bit.
5. The PM20 bit in the PM2 register becomes effective when the PLC07 bit in the PLC0 register is set to 1 (PLL on). Change the PM20 bit when the PLC07 bit is set to 0 (PLL off).
6. Set the CM06 bit to 1 (division by 8 mode) before changing back the operation mode from on-chip oscillator mode to high- or middle-speed mode.
7. When the CM21 bit is set to 0 (on-chip oscillator turned off) and the CM05 bit is set to 1 (main clock turned off), the CM06 bit is fixed to 1 (divide-by-8 mode) and the

Sub clock oscillation
Set the CM20 bit to 0 (oscillation stop, re-oscillation detection function disabled) before transiting.
Set the PM20 bit to 0 (2 waits) when PLL clock > 16MHz.
CM15 bit is fixed to 1 (drive capability High).
