Oscillator Circuit
Resonator
Recommended Circuit
Ceramic or crystal resonator
External clock
Cautions 1. When using system clock oscillator, wire the portion enclosed in broken lines in the figure
as follows to avoid adverse influences on the wiring capacitance:
Keep the wiring length as short as possible.
Do not cross the wiring over the other signal lines.
Do not route the wiring in the vicinity of lines through which a high fluctuating current
flows.
Always keep the ground point of the capacitor of the oscillator circuit at the same
potential as GND.
Do not connect the power source pattern through which a high current flows.
Do not extract signals from the oscillator.
2. When using ceramic resonator or crystal resonator, frequency multiple rate should be
specified to as 1 by mask option. The device does not operate in other frequency multiple
rate.
