Use a crystal resonator that has the characteristics shown in table 19.3 and the same resonance frequency as the system clock ( φ). XTAL CL AT-cut parallel-resonance type EXTAL C0 LRs Figure 19.3 Crystal Resonator Equivalent Circuit Table 19.3 Crystal Resonator Parameters Frequency (MHz) 2 4 8 12 16 20 RS max ( Ω Ω Ω Ω) 500 120 80 60 50 40 C0 max (pF) 7 7 7 7 7 7 Note 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 designing the board, place the crystal resonator and its load capacitors as close as possible to the XTAL and EXTAL pins.
