Transition of normal mode
Figure 1.8.8. State transition diagram of power control mode
Transition of stop mode, wait mode
Preliminary Specifications Rev. 0.9
Specifications in this manual are tentative and subject to change.
All oscillators stopped
All oscillators stopped
All oscillators stopped
Note 1: When bit PM21 = "0" (system clock protective function unused).
Note 2: The ring oscillator clock divided by 8 provides BCLK.
Note 3: Switch clock after oscillation of main clock is sufficiently stable.
Note 4: Switch clock after oscillation of sub clock is sufficiently stable.
Note 5: Change CM06 after changing CM17 and CM16.
