I'm just designing a new circuit using the Tiny261. I have a question regarding the AREF pin. It says in the datasheet (page 154 just above table 19-3) "The internal voltage reference options may not be used if an external voltage is being applied to the AREF pin." Does that apply if I select VCC as my voltage reference? I'm in need of one more I/O and that's the last one I have left, but I still need ADC on other pins.
I've read the datasheet several times, and that's the only reference to not using AREF that I can find.
