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;
