23.7.2
Since various characteristics related to the resonator are closely linked to the user's board design,
thorough evaluation is necessary on the user's part, using the resonator connection examples
shown in this section as a reference. As the parameters for the resonator will depend on the
floating capacitance of the resonator and the mounting circuit, the parameters should be
determined in consultation with the resonator manufacturer. The design must ensure that a voltage
exceeding the maximum rating is not applied to the resonator pin.
23.7.3
When using the crystal resonator, place the crystal resonator and its load capacitors as close as
possible to the XTAL and EXTAL pins. Other signal lines should be routed away from the
oscillation circuit as shown in figure 23.6 to prevent induction from interfering with correct
oscillation.
