[Supplement]

In addition to the techniques for designing a circuit board, the following options and programming are effective to

prevent and avoid the defects (the malfunction or a runaway program).

• If signals are input from external sources when the microcontroller power supply is unstable, select the higher

capacity voltage (N-channel open drain) output type for the input pin, and add a damping resistor close to the

pin.

• When the external signals are input to pins, the chattering of the key must be removed.

• The data should be output periodically from the pins using the output instruction (OP or SPB).

• To read the data input to the I/O common pins, the output value should be set to ‘1’ using the output instruction

(OP or SPB).

7. Unused Pins

• See the user’s manual for each microcontrollers or the final edition of the specification sheet.
