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.
