From AVR Studio 4.18 SP2, both devices' XML are as follow:
<ADTS3_MASK>0x10</ADTS3MASK>

whereas the datasheet read as follow:

ADCSRB
Bit   7     6    5  4   3    2     1     0
    ADHSM ACME MUX5 - ADTS3 ADTS2 ADTS1 ADTS0

The header of in avr-libc head(2179) for
iom16u4.h
iom32u4.h

are as follow:
iom16u4.h:#define ADTS3 4
iom32u4.h:#define ADTS3 4

whereas they should be 3

A request has also been made to support.atmel.no
