23.5.3
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 to prevent induction from interfering with correct oscillation. See figure 23.6.
Figure 23.7 shows the external circuitry recommended for the PLL circuit. Separate PLLVcc and
PLLVss from the other Vcc and Vss lines at the board power supply source, and be sure to insert
bypass capacitors CPB and CB close to the pins.
Notes on Board Design
Note: * CB and CPB are laminated ceramic capacitors.
