Sequence of Turning on Power of A/D Converter and Applying Analog Input
Handling Pins When A/D Converter is Not Used
Note on Turning on Power
Stabilization of supply voltage
• Be sure to turn on digital power (Vcc) before applying signals to the A/D converter and applying analog input
• Be sure to turn off the power of A/D converter and analog input before turning off the digital power source.
• Be sure not to apply AVR exceeding AVcc when turning on and off. (No problems occur if analog and digital
• If the A/D converter is not used, connect the pins under the following conditions: “AVcc=AVR=Vcc,” and
• For preventing malfunctions on built-in step-down circuit, maintain a minimum of 50 s of voltage rising time
• A sudden change in the supply voltage may cause the device to malfunction even within the specified V
signals (AN0 to AN7 pins).
