Caution When using system clock oscillator, wire the portion enclosed in broken lines in the figure as
follows to avoid adverse influences on the wiring capacitance:
• Keep the wiring length as short as possible.
• Do not cross the wiring over the other signal lines.
• Do not route the wiring in the vicinity of lines through which a high fluctuating current flows.
• Always keep the ground point of the capacitor of the oscillator circuit at the same potential
as GND.
• Do not connect the power source pattern through which a high current flows.
• Do not extract signals from the oscillator.
