reset pin as input; AVR32DA28

[flexphperia]

I am trying to use reset pin as input but I have a compile time error:
badArg ("analogRead called with constant pin that is not a valid analog pin");

Of course I've selected Optiboot and Reset pin function as Input. My MCU is AVR32DA28.

No matter what I call:
analogRead(PIN_PF6);
analogRead(22);

My read of the datasheet is that PF6 is not available for any analog functions - input or output. At best, you can do a digitalRead, but not a digitalWrite.
