Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67,
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
The value of the limiting resistance should be set so that when the +B signal is applied the input current to
Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input
Note that if a +B signal is input when the microcontroller current is off (not fixed at 0 V), the power supply
Note that if the +B input is applied during power-on, the power supply is provided from the pins and the
Care must be taken not to leave the +B input pin open.
Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input
