oscillation clock, do so after 10
A voltage oscillation stabilization time is required after the supply voltage reaches
1.59 V (TYP.). If the supply voltage rises from 1.59 V (TYP.) to 2.07 V (TYP.) within
the power supply oscillation stabilization time, the power supply oscillation
stabilization time is automatically generated before reset processing.
It is not necessary to wait for the oscillation stabilization time when an external clock
input from the EXCLK pin is used.
The X1/P121 and X2/EXCLK/P122 pins are in the input port mode after a reset
release.
The CMC register can be written only once after reset release, by an 8-bit memory
manipulation instruction.

Set the X1 clock after the supply voltage has reached the operable voltage of the

Set the external main system clock after the supply voltage has reached the operable

Be sure to clear bit 1 of the PER0 register to 0.
Be sure to confirm that MCS = 0 or CLS = 1 when setting MSTOP to 1. In addition,
stop peripheral hardware that is operating on the high-speed system clock.
If the switching is made immediately after the internal high-speed oscillation clock is
restarted, the accuracy of the internal high-speed oscillation cannot be guaranteed
