Notes: 1. Since the circuit constants change depending on the crystal or ceramic oscillator and stray
capacitance of the board, the user should consult with the crystal or ceramic oscillator
manufacturer to determine the circuit parameters.
2. Wiring among OSC
, OSC

, and elements should be as short as possible, and must not cross
other wiring (see figure 16).
