be located with the Vcc line just as in the above-mentioned Vss line.
Connect the power supply line of external devices connected to the microcomputer with the bus and the
power supply line of the microcomputer in the shortest possible distance.
When using the multilayer boards, make sure that one of the middle layer is Vss side, and the other one
Use the broader wiring width than that of the other signal wire for the Vss and Vcc lines.
When using the double-sided boards, one side must be located with looped or mesh form to the Vss
when connecting external devices. That may causes noise of the power supply line.
