Cautions 1. When using the XT1 oscillator, wire as follows in the area enclosed by the broken lines in the

Resonator
2. The XT1 oscillator is designed as a low-amplitude circuit for reducing power consumption,
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.
and is more prone to malfunction due to noise than the X1 oscillator. Particular care is
therefore required with the wiring method when the XT1 clock is used.
