■ NOTES ON USE
• Be sure to bypass the AVDD, DVDD, VRT and VRB pins to the ground using a high-frequency capacitor.
The high-frequency capacitor should be connected as near the pin as possible.
• Provide four clocks or more immediately after the power up to prevent current dissipation due to the
indeterminate internal logic.

Any semiconductor devices have inherently a certain rate of
failure. You must protect against injury, damage or loss from
such failures by incorporating safety design measures into your
facility and equipment such as redundancy, fire protection, and
prevention of over-current levels and other abnormal operating
conditions.
If any products described in this document represent goods or
technologies subject to certain restrictions on export under the
Foreign Exchange and Foreign Trade Control Law of Japan, the
prior authorization by Japanese government should be required
for export of those products from Japan.
