Crystal Resonator: Figure 19.3 shows an equivalent circuit of the crystal resonator. The crystal
resonator should have the characteristics listed in table 19.2.

Use a crystal resonator with a frequency equal to the system clock frequency ( ).
Notes on Board Design: When a crystal resonator is connected, the following points should be
noted:
Other signal lines should be routed away from the oscillator circuit to prevent induction from
interfering with correct oscillation. See figure 19.4.
When the board is designed, the crystal resonator and its load capacitors should be placed as close
as possible to the XTAL and EXTAL pins.
