I checked the manual of the ATMega4809 and saw inside the "Multiplexed Signals Table" (page19) that I could use the pins D8 (PE3), D11(PE0), D12(PE1), D13(P2) as normal Analog Inputs AIN8-11. But I dont know if this is possible with the arduino software?
I also could use the AREF pin (PD07) as AIN7, too.
