Figure 8.12 State Transition to Stop Mode and Wait Mode
Figure 8.12 shows the State Transition to Stop Mode and Wait Mode. Figure 8.13 shows the State Transition
in Normal Operating Mode.
Table 8.8 shows a state transition matrix describing allowed transition and setting. The vertical line shows
current state and horizontal line show state after transition.

NOTES:
1.
2.PLL operating mode can be entered from high-speed mode. Similarly, PLL operating mode can be changed back to high-speed mode.
3.Write to registers CM0 and CM1 per 16 bits with the CM21bit in the CM2 register = 0 (on-chip oscillator stops).
4.The on-chip oscillator clock divided by 8 provides the CPU clock.
5.Before entering stop mode, be sure to set the CM20 bit in the CM2 register to 0 (oscillation stop, re-oscillation detection function disabled).

Do not go directly from PLL operating mode to wait or stop mode.
Since the operation starts from the main clock after exiting stop mode, the time until the CPU operates can be reduced.
