Notes 1. The oscillation frequency only indicates the oscillator characteristics.
2. The oscillation stabilization time is necessary for oscillation to be stabilized after VDD application or
STOP mode release.
Caution When using the system clock oscillator, wire as follows in the area enclosed by the dotted lines
in the above figure, to avoid an adverse effect from wiring capacitance.
Keep the wiring length as short as possible.
Do not cross the wiring with other signal lines. Do not route the wiring near a signal line
through which a large current flows.
Always make the ground point of the oscillator capacitor the same potential as GND. Do not
ground the capacitor to a ground pattern through which a large current flows.
Do not fetch signals from the oscillator.
