When Using an External Crystal Resonator: Place the crystal resonator, capacitors CL1 and
CL2, and damping resistor R close to the EXTAL and XTAL pins. To prevent induction from
interfering with correct oscillation, use a common grounding point for the capacitors connected to
the resonator, and do not locate a wiring pattern near these components.
Decoupling Capacitors: As far as possible, insert a laminated ceramic capacitor of 0.01 to 0.1 µF
as a passive capacitor for each V
the LSI power supply pins, and use components with a frequency characteristic suitable for the
LSI operating frequency, as well as a suitable capacitance value.

When Using a PLL Oscillator Circuit: Keep the wiring from the PLL V
pattern to the power supply pins short, and make the pattern width large, to minimize the
inductance component. Ground the oscillation stabilization capacitors C1 and C2 to V
