1. The parameter is based on VSS5  AVSS5  0.0 V.

2. AVCC5 and AVRH5 must not exceed VDD5  0.3 V.

■ Use within recommended operating conditions.

■ Use with DC voltage (current).

■ B signals are input signals that exceed the VDD5 voltage. B signals 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 the rated value at any time, either

instantaneously or for an extended period, 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 power supply 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), power is supplied through the +B input pin; therefore, the

microcontroller may partially operate.

■ Note that if the B signal is input at power-on, since the power is supplied through the pin, the power-on reset may not function in the power supply

voltage.

■ Do not leave B input pins open.
