HANDLING DEVICES  
1. Preventing Latchup  
Latchup occurs in a CMOS IC if a voltage greater than VCC or less than VSS is applied to an input or output pin  
or if the voltage applied between VCC and VSS exceeds the rating.  
If latchup occurs, the power supply current increases rapidly resulting in thermal damage to circuit elements.  
Therefore, ensure that maximum ratings are not exceeded in circuit operation.  
For the same reason, also ensure that the analog supply voltage does not exceed the digital supply voltage.  
2. Treatment of Unused Pins  
Leaving unused input pins unconnected can cause misoperation. Always pull-up or pull-down unused pins.  
3. External Reset Input  
To reliably reset the controller by inputting an “L” level to the RST pin, ensure that the “L” level is applied for at  
least five machine cycles. Take particular note when using an external clock input.  
4. VCC and VSS Pins  
Ensure that all VCC pins are at the same voltage. The same applies for the VSS pins.  
5. Cautions When Using an External Clock  
Drive the X0 pin only when using an external clock.

6. A/D Converter Power Supply and the Turn-on Sequence for Analog Inputs  
Always cut the A/D converter power supply (AVCC, AVRH, AVRL) and analog inputs (AN0 to AN7) before  
disconnecting the digital power supply (VCC).  
When turning the power on or off, ensure that AVRH does not exceed AVCC.  
Also, when using the analog input pins as input ports, ensure that the input voltage does not exceed AVCC.
