*1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscil-

lator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the

oscillation characteristics of components must be carefully evaluated.
