1.Set the FMSTP bit in the FMR0 register to 1 after setting the FMR01 bit in the FMR0 register to 1 (CPU rewrite
2.Wait until clock stabilizes to switch clock source of the CPU clock to the main clock or sub clock.
3.Add tps µs wait time by program. Do not access the flash memory during this wait time.
4.Before entering wait mode or stop mode, be sure to set the FMR01 bit to 0 (CPU rewrite mode disabled).
