The X1 and X2 pins should be open as shown in figure 24.8.

24.9.1
Since all kinds of characteristics of the resonator are closely related to the board design by the
user, use the example of resonator connection in this document for only reference; be sure to use
an resonator that has been sufficiently evaluated by the user. Consult with the resonator
manufacturer about the resonator circuit ratings which vary depending on the stray capacitances of
the resonator and installation circuit. Make sure the voltage applied to the oscillator pins does not
exceed the maximum rating.
24.9.2
When using a crystal resonator, the crystal resonator and its load capacitors should be placed as
close as possible to the XTAL and EXTAL pins.
Other signal lines should be routed away from the oscillator circuit to prevent inductive
interference with the correct oscillation as shown in figure 24.9.
