Note:
When the clock mode is switched, do not switch to low power consumption mode and other clock
mode before this switching is completed. Confirm the completion of clock mode switching by
referring to the MCM and SCM bits of the clock selection register (CKSCR). If the mode is switched
to another clock mode or low-power-consumption mode before completion of switching, the mode
may not be switched.
