Caution To use a system clock oscillator circuit, perform the wiring in the area enclosed by the dotted
line in the above figure as follows, to avoid adverse wiring capacitance influences:
Keep wiring length as short as possible.
Do not cross a signal line with some other signal lines. Do not route the wiring in the vicinity
of lines through which a large current flows.
Always keep the oscillator circuit capacitor ground at the same potential as GND. Do not
ground the capacitor to a ground pattern, through which a large current flows.
Do not extract signals from the oscillator circuit.
