Using RC oscillator to generate the external clock needs to connect one 0.1uF bypass capacitor from XIN of
micro-controller to VSS. The VSS of the bypass capacitor must been connected to the VSS pin of micro-controller first.
It is necessary to get a stable oscillator output. Don’t connect the VSS of the bypass capacitor to the power source
individually. That makes the oscillator to been affected by the power ground easily. The external oscillator circuit must
approach to the micro-controller as closely as possible.
