Caution

If using an oscillation circuit, wire the area enclosed in the dotted line in the figure in the manner

indicated below in order to avoid negative effects such as from stray capacitance of wires.

• Keep wiring as short as possible.

• Do not cross other signal lines. Do not design wiring close to lines with large fluctuating

current.

• Make sure that the connection point of the oscillation circuit’s capacitor has the same

potential as VDD.

• Do not extract signals from the oscillation circuit.
