Arrangement of Signal Lines
• In order to prevent generation of electromagnetic induction noise caused by mutual inductance, do not arrange
a large current signal line near the circuits that are sensitive to noise such as the oscillation unit and analog input
unit.
• When a signal line is parallel with a high-speed line in long distance or intersects a high-speed line, noise may
generated by mutual interference between the signals and it may cause a malfunction.
Do not arrange a high-speed signal line especially near circuits that are sensitive to noise such as the oscillation
unit and analog input unit.
