◇Caution
（１） About absolute maximum rating
When the absolute maximum rating such as the applied voltage and the ranges of the operating temperature is exceeded, LSI might be destroyed.
Please apply neither voltage nor the temperature that exceeds the absolute maximum rating.
Please execute physical measures for safety such as fuse when it is thought to exceed the absolute maximum rating, and examine it so that
the condition to exceed the absolute maximum rating is not applied to LSI.
（２） About GND Voltage
In any state of operation must be the lowest voltage about the voltage of the terminal GND. Please actually confirm the voltage of each terminal
is not a voltage that is lower than the terminal GND including excessive phenomenon.
（３） About design of overheating malfunction preventive circuit
Please design overheating malfunction preventive circuit with an enough margin in consideration of a permissible loss in the state of using actually.
（４） About the short between terminals and the mounting by mistake
Please note the direction and the gap of position of LSI enough about LSI when you mount on the substrate. LSI might be destroyed when mounting
by mistake and energizing. Moreover, LSI might be destroyed when short-circuited by entering of the foreign substances between the terminal
and GND, between terminals, between the terminal and the power supply of LSI.
（５） About operation in strong electromagnetic field
Use in strong electromagnetic field has the possibility of malfunctioning and evaluate it enough, please.
（６） Please note not to be beyond the package permissible range, When SPVDD is set.
