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 VREFH0 and VREFL0 pins, between the VREFH1 and VREFL1 pins, and between the VREFH2 and VREFL2 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/VREFH0/VREFH1/VREFH2 and VCC can be set individually within the operating range.
Note 2. When powering on the VCC and AVCC0/AVCC1/AVCC2/VREFH0/VREFH1/VREFH2 pins, power them on at the same time or
the VCC pin first and then the AVCC0/AVCC1/AVCC2/VREFH0/VREFH1/VREFH2 pin.
