stabilizes.
When using the subclock oscillator, wire as follows in the area enclosed by the broken lines in the
above figures to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the 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
• Do not ground the capacitor to a ground pattern through which a high current flows.
• Do not fetch signals from the oscillator.
The subclock oscillator is designed as a low-amplitude circuit for reducing power consumption,
and is more prone to malfunction due to noise than the main clock oscillator.
Particular care is therefore required with the wiring method when the subclock is used.
For the resonator selection and oscillator constant, customers are requested to either evaluate the
oscillation themselves or apply to the resonator manufacturer for evaluation.
