21.5.3
When using the crystal resonator, place the crystal resonator and its load capacitors as close to the
XTAL and EXTAL pins as possible. Other signal lines should be routed away from the oscillation
circuit as shown in Figure 21.7 to prevent induction from interfering with correct oscillation.
Figure 21.8 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.
