Even if the MCK bit is set (1) while the system is operating with the main clock as
the CPU clock, the operation of the main clock does not stop. It stops after the
CPU clock has been changed to the subclock.
Before setting the MCK bit from 0 to 1, stop the on-chip peripheral functions
operating with the main clock.
When the main clock is stopped and the device is operating with the subclock,
clear (0) the MCK bit and secure the oscillation stabilization time by software
before switching the CPU clock to the main clock or operating the on-chip
peripheral functions.
