3. AVcc must be under condition of VccQ – 0.3 V
≤
AVcc
≤
VccQ + 0.3 V. If the A/D and
D/A converters are not used, do not leave the AVcc and AVss pins open. Connect AVcc
to VccQ, and connect AVss to VssQ.
4. Current dissipation values shown are the values at which all output pins are without
load under conditions of V
