13.2 PCB Layout
For reference, here is a example layout for oscillator circuit.
Note :
Minimize the wiring length. Do not allow the wiring to intersect with other signal conductors.
Do not allow the wiring to come near changing high current. Set the potential of the
grounding position of the oscillator capacitor to that of VSS. Do not ground it to any ground
pattern where high current is present. Do not fetch signals from the oscillator.
