for the instruction execution

time.

Time required to oscillation after reset or STOP mode release. Use a resonator that can stabilize

oscillation before the oscillation stabilization time elapses.

Caution

When using the system clock oscillator, wire as follows in the area enclosed by the broken 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 high fluctuating current flows.

••••

Always make the ground point of the oscillator capacitor the same potential as V

SS0

••••

Do not ground the capacitor to a ground pattern through which a high current flows.

••••

Do not fetch signals from the oscillator.

Remark

For the resonator selection and oscillator constant, customers are required to either evaluate the

oscillation themselves or apply to the resonator manufacturer for evaluation.
