*1. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristicsauthentication. The oscillation frequency range is not guaranteed.
Specifically, the characteristics can vary greatlydue to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
