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.
