1.
Preventing latch-up
CMOS IC chips may suffer latch-up under the following conditions :
A voltage higher than VCC or lower than VSS is applied to an input or output pin.
A voltage higher than the rated voltage is applied between VCC and VSS.
The AVCC power supply is applied before the VCC voltage.
Latch-up may increase the power supply current drastically, causing thermal damage to the device.
Use meticulous care not to exceed the rating.
For the same reason, also be careful not to let the analog power-supply voltage (AVCC, AVR) exceed the digital
power-supply voltage.
2.
Treatment of unused pins
Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the
device. Therefore, they must be pulled up or pulled down through resistors. In this case, those resistors should
be more than 2 k
.
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.
3.
Using external clock
To use external clock, drive the X0 pin and leave X1 pin open.
