Oscillator Circuit

The oscillator circuit can be selected from three options by using the jumper J1: a surface
mount-type 10 MHz crystal oscillator module, a DIP-type crystal oscillator module or a crystal
resonator.
By default, the surface mount-type 10 MHz crystal oscillator module is selected.

Note: The shaded sections in the above diagram have only patterns available. When using the resonator Y1, please be
sure to add capacitors (C3, C4) and a resistor (R4).
