4.5.2 Notes on Board Design
When connecting a crystal oscillator, observe the following precautions:
• To prevent induction from interfering with correct oscillation, do not route any signal lines
near the oscillator circuitry.
• When designing the board, place the crystal oscillator and its load capacitors as close as
possible to the XTAL and EXTAL pins.
Figure 4.5 shows the precautions regarding oscillator block board settings.
