Details:

This is from the iox256d3.h file

/* Negative input multiplexer selection */
typedef enum ADC_CH_MUXNEG_enum
{
    ADC_CH_MUXNEG_PIN0_gc = (0x00<<0),  /* Input pin 0 */
    ADC_CH_MUXNEG_PIN1_gc = (0x01<<0),  /* Input pin 1 */
    ADC_CH_MUXNEG_PIN2_gc = (0x02<<0),  /* Input pin 2 */
    ADC_CH_MUXNEG_PIN3_gc = (0x03<<0),  /* Input pin 3 */
    ADC_CH_MUXNEG_PIN4_gc = (0x04<<0),  /* Input pin 4 */
    ADC_CH_MUXNEG_PIN5_gc = (0x05<<0),  /* Input pin 5 */
    ADC_CH_MUXNEG_PIN6_gc = (0x06<<0),  /* Input pin 6 */
    ADC_CH_MUXNEG_PIN7_gc = (0x07<<0),  /* Input pin 7 */
} ADC_CH_MUXNEG_t;

pins 4 to 7 are incorrect with the datasheet for the device.

File iox256c3.h has the correct values. Shown below.

/* Negative input multiplexer selection */
typedef enum ADC_CH_MUXNEG_enum
{
    ADC_CH_MUXNEG_PIN0_gc = (0x00<<0),  /* Input pin 0 */
    ADC_CH_MUXNEG_PIN1_gc = (0x01<<0),  /* Input pin 1 */
    ADC_CH_MUXNEG_PIN2_gc = (0x02<<0),  /* Input pin 2 */
    ADC_CH_MUXNEG_PIN3_gc = (0x03<<0),  /* Input pin 3 */
    ADC_CH_MUXNEG_PIN4_gc = (0x00<<0),  /* Input pin 4 */
    ADC_CH_MUXNEG_PIN5_gc = (0x01<<0),  /* Input pin 5 */
    ADC_CH_MUXNEG_PIN6_gc = (0x02<<0),  /* Input pin 6 */
    ADC_CH_MUXNEG_PIN7_gc = (0x03<<0),  /* Input pin 7 */
} ADC_CH_MUXNEG_t;
