*1 : If the maximum current to /from an input is limited by some means with external components, the ICLAMP rating
supersedes the VI rating.
*2 : • Applicable to pins : P00 to P07, P30 to P37, P40 to P43, P50
• Use within recommended operating conditions.
• Use at DC voltage (current)
• The +B signal should always be applied with a limiting resistance placed between the +B signal and the
microcontroller.
• The value of the limiting resistance should be set so that when the +B signal is applied the input current to
the microcontroller pin does not exceed rated values, either instaneously or for prolonged periods.
• Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input
potentional may pass through the protective diode and increase the potentional at the VCC pin, and this may
affect other devices.
• Note that if a +B signal is input when the microcontroller current is off (not fixed at 0 V) , the power supply
is provided from the pins, so that incomplete operation may result.
• Note that if the +B input is applied during power-on, the power supply is provided from the pins and the
resulting supply voltage may not be sufficient to operate the power-on result.
• Care must be taken not to leave the +B input pin open.
• Note that analog system input pins other than the A/D input pins (LCD drive pins, comparator input pins,
etc.) cannot accept +B signl input.
