Caution When using system clock oscillation circuits, to reduce the effect of the wiring capacitance,
etc, wire the area indicated by dotted-line as follows:
Make the wiring as short as possible.
Do not allow the wiring to intersect other signal lines. Keep it away from other lines in which
varying high currents flow.
Make sure that the ground point of the oscillation circuit capacitor is always at the same electric
potential as V
SS
. Do not allow the wiring to be grounded to a ground pattern in which very high
currents are flowing.
Do not extract signals from the oscillation circuit.
