MC81F4204April 24, 2012 Ver.1.41 89Xout and Xin pins can be used as normal pins13.2 PCB LayoutFor 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 thegrounding position of the oscillator capacitor to that of V SS . Do not ground it to any groundpattern where high current is present. Do not fetch signals from the oscillator.Figure 13-4 Internal RC OscillatorFigure 13-5 Layout of Oscillator PCB circuit
