Note 1: Switch clock after oscillation of main clock is sufficiently stable.
Note 2: Switch clock after oscillation of sub clock is sufficiently stable.
Note 3: Change CM06 after changing CM17 and CM16.
Note 4: T ransit in accordance with arrow.
Note 5: The device can be operated with a low supply voltage (VCC = 3.0 V)
in only low power dissipation mode. Always make sure the power
supply voltage VCC is switched between 5.0 V and 3.0 V in this mode
