Function
When using the XT1 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
• 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 XT1 oscillator is designed as a low-amplitude circuit for reducing power
consumption, 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.
The oscillator constants shown above are reference values based on evaluation in a
specific environment by the resonator manufacturer. If it is necessary to optimize the
oscillator characteristics in the actual application, apply to the resonator
manufacturer for evaluation on the implementation circuit.
When doing so, check the conditions for using the AMPH bit, RMC register, and
whether to enter or exit the STOP mode.
The oscillation voltage and oscillation frequency only indicate the oscillator
characteristic.
