<Precautions>
When the oscillation rise time at power switch-on is compared between a ceramic and a crystal resonator, it is
known that the crystal resonator is about 10 to 100 times slower to rise than the ceramic resonator. Therefore, when
a crystal resonator is used, system operation as a switching regulator at power switch-on becomes unstable. To
avoid this problem, it is recommended that you use a ceramic oscillator because it has a short rise time and, hence,
ensures stable operation.
