s HANDLING DEVICES
Special care is required for the following when handling the device:
Preventing latch-up
Treatment of unused pins
Using external clock
Precautions for when not using a sub clock signal
Notes on during operation of PLL clock mode

Connection of Unused Pins of A/D Converter
Notes on Energization
Stabilization of power supply voltage
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.
For the same reason, also be careful not to let the analog power-supply voltage (AVCC, AVRH) exceed the
digital power-supply voltage.
2.
Treatment of unused pins
Unused input pins may be left open when the input is disabled (corresponding bit of Port Input Enable register
PIER = 0).
Leaving unused input pins open when the input is enabled may result in misbehavior and possible permanent
damage of the device. Therefore they must be pulled up or pulled down through resistors. To prevent latchup,
those resistors should be more than 2 kOhm.
Unused bidirectional pins should be set to the output state and can be left open, or the input state with either
input disabled or external pull-up/pull-down resistor as described above.
3.
Using external clock
To use external clock, drive the X0 pin and leave X1 pin open.
4.
Precautions for when not using a sub clock signal
If you do not connect pins X0A and X1A to an oscillator, use a pull-down resistor on the X0A pin, and
leave the X1A pin open.
5.
Notes on during operation of PLL clock mode
If the PLL clock mode is selected and no external oscillator is operating or no external clock is supplied, the
microcontroller attempts to be working with the freely oscillating PLL. Performance of this operation, however,
cannot be guaranteed.
6.
Power supply pins (VCC/VSS)
Ensure that all VCC-level power supply pins are at the same potential. In addition, ensure the same for all
VSS-level power supply pins. If there are more than one VCC or VSS system, the device may operate
incorrectly even within the guaranteed operating range.
