*3: Applicable to the following pins: P00 to P07, P10, P11, P13 to P16, P20 to P22, P40 to P43, P50 to P53,
P60 to P67, P90 to P94, PA0 to PA7, PB0 to PB4, PC0 to PC7, PE0 to PE7, PF0, PF1, PG1 and PG2 (P40
to P43, P50 to P53, P94, PB2 to PB4 and PC4 to PC7 are only available on the MB95410H Series.)
Use under recommended operating conditions.
Use with DC voltage (current).
The HV (High Voltage) signal is an input signal exceeding the VCC voltage. Always connect a limiting resistor
between the HV (High Voltage) signal and the microcontroller before applying the HV (High Voltage) signal.
The value of the limiting resistance should be set so that when the HV (High Voltage) signal is applied the
input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged
periods.
When the microcontroller drive current is low, such as in low power consumption modes, the HV (High
Voltage) input potential may pass through the protective diode to increase the potential of the VCC pin, and
thus affects other devices.
If the HV (High Voltage) signal is input when the microcontroller power supply is off (not fixed at 0 V), since
power is supplied from the pins, incomplete operations may be executed.
If the HV (High Voltage) input is input after power-on, since power is supplied from the pins, the voltage
of power supply may not be sufficient to enable a power-on reset.
Do not leave the HV (High Voltage) input pin unconnected.
Example of a 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.
