(3) Note on Board Design
When a crystal resonator is connected, the following points should be noted.
Other signal lines should be routed away from the oscillator circuit to prevent induction from
interfering with correct oscillation. See figure 10.4.
When designing the board, place the crystal resonator and its load capacitors as close as
possible to the OSC1 and OSC2 pins.
