3.2 Recommended Oscillator Layout
General guidance for PCB layout:
• Keep the wiring length as short as possible
• Do not cross the wiring with other signal lines
• Do not route this circuit close to a signal line with high fluctuating current flow
• Always make the ground point of the oscillator capacitor the same potential as AWOVSS
• Do not ground the capacitor to a ground pattern with high current flow
• Do not tap signals from the oscillator
