Caution: Permanent damage to the LSI may result if absolute maximum ratings are exceeded.
To preclude any malfunctions due to noise interferences, insert capacitors of high frequency characteristics between the VCC
and VSS pins, between the AVCC0 and AVSS0 pins, and between the VREFH0 and VREFL0 pins. Place capacitors of 0.1 µF or
so as close to every power pin and use the shortest and heaviest possible traces.
Connect the VCL pin to a VSS pin via a 0.1 µF (±20% accuracy) capacitor. The capacitor must be placed as close to the pin as
possible.
Note 1. Ports 12, 13, 16, and 17 are 5 V tolerant.
Note 2. Set to the same potential as VCC. When the A/D converter is not used, do not leave the AVCC0, VREFH0, AVSS0, and VREFL0
pins open. Connect the AVCC0 and VREFH0 pins to VCC, and the AVSS0 and VREFL0 pins to VSS, respectively.
Note 3. The maximum value is 6.5 V.
