5.3.2 Notes on Board Design
When using a crystal resonator (ceramic resonator), place the resonator and its load capacitors as
close as possible to the OSC₁ and OSC₂ pins. Other signal lines should be routed away from the
oscillator circuit to prevent induction from interfering with correct oscillation (see figure 5.7).
