Caution: Permanent damage to the MCU may result if absolute maximum ratings are exceeded.
To preclude any malfunctions due to noise interference, insert capacitors of high frequency characteristics between the VCC and
VSS pins, between the AVCC0 and AVSS0 pins, between the AVCC1 and AVSS1 pins, between the AVCC2 and AVSS2 pins,
between the VREF and AVSS2 pins. Place capacitors of about 0.1 μF as close as possible to every power supply pin and use the
shortest and heaviest possible traces.
Connect the VCL pin to a VSS pin via a 4.7 μF capacitor. The capacitor must be placed close to the pin.
Do not input signals or an I/O pull-up power supply to ports other than 5-V tolerant ports while the device is not powered.
The current injection that results from input of such a signal or I/O pull-up may cause malfunction and the abnormal current that
passes in the device at this time may cause degradation of internal elements.
Even if –0.3 to +6.5 V is input to 5-V tolerant ports, it will not cause problems such as damage to the MCU.
Note 1. Ports B1 and B2 are 5 V tolerant.

Note 1. AVCC0/AVCC1/AVCC2/VREF and VCC can be set individually within the operating range.
Note 2. When powering on the VCC and AVCC0/AVCC1/AVCC2/VREF pins, power them on at the same time or the VCC pin first and
then the AVCC0/AVCC1/AVCC2/VREF pin.
