* Both C3 and C4 must be use J rank (±5%) and CH characteristics.
(Not in need of high precision, use K rank (±10%) and SL characteristics.)
(Notes) Please place the oscillation-related parts as close to the oscillation pins as possible with the shortest
possible pattern length since the circuit pattern affects the oscillation frequency.
If you use other oscillators herein, we provide no guarantee for the characteristics.
