AVCC
AREF
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.
Output from the inverting Oscillator amplifier.
AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally con-
nected to V
through a low-pass filter.
This is the analog reference pin for the A/D Converter.
CC
, even if the ADC is not used. If the ADC is used, it should be connected to V
