*2. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the

oscillation frequency range is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting condi-

tions, so the oscillation characteristics of components must be carefully evaluated.
