Use within recommended operating conditions.
Use at DC voltage (current).
The +B signal is an input signal exceeding VCC voltage. The +B signal should always be applied by connecting
a limiting resistor between the +B signal and the microcontroller.
The value of the limiting resistor should be set so that the current input to the microcontroller pin does not
exceed rated values at any time regardless of instantaneously or constantly when the +B signal is input.
Note that when the microcontroller drive current is low, such as in the low power consumption modes, the
+B input potential can increase the potential at the VCC pin via a protective diode, possibly affecting other
devices.
Note that if the +B signal is input when the microcontroller is off (not fixed at 0 V), since the power is supplied
through the pin, the microcontroller may operate incompletely.
Note that if the +B signal is input at power-on, since the power is supplied through the pin, the power supply
voltage may become the voltage at which a power-on reset does not work.
Do not leave +B input pin open.
Note that analog input/output pins cannot accept +B signal input.
Example of recommended circuit :
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.
