*3 :
Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40, P41, P44 to P47, P50 to P57,
P60 to P64
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 instantaneously or for prolonged periods.
Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input
potential may pass through the protective diode and increase the potential 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/output pins other than the A/D input pins (LCD drive pins, comparator input
pins, etc.) cannot accept
+B signal input.
Sample recommended circuits :
WARNING: 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.
