・

See "■ List of Pin Functions" and "■ I/O Circuit Type" about +B input available pin.

・

Use within recommended operating conditions.

・

Use at DC voltage (current) the +B input.

・

The +B signal should always be applied a limiting resistance placed between the +B signal and the device.

・

The value of the limiting resistance should be set so that when the +B signal is applied the input current to

the device pin does not exceed rated values, either instantaneously or for prolonged periods.

・

Note that when the device drive current is low, such as in the low-power consumpsion modes, the +B input

potential may pass through the protective diode and increase the potential at the VCC and AVCC pin, and

this may affect other devices.

・

Note that if a +B signal is input when the device power supply is off (not fixed at 0V), the power supply is

provided from the pins, so that incomplete operation may result.

・

The following is a recommended circuit example (I/O equivalent circuit).

Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature,

etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
