Analog-to-Digital Converter (ADC)
Register 11: ADC Sample Sequence Input Multiplexer Select 0 (ADCSSMUX0), offset 0x040
This register defines the analog input configuration for each sample in a sequence executed with
Sample Sequencer 0.
This register is 32-bits wide and contains information for eight possible samples.

Description
Reserved bits return an indeterminate value, and should never be
changed.
The MUX7 field is used during the eighth sample of a sequence
executed with Sample Sequencer 0. It specifies which of the
analog inputs is sampled for the analog-to-digital conversion. The
value set here indicates the corresponding pin, for example, a
value of 1 indicates the input is ADC1.
Reserved bits return an indeterminate value, and should never be
changed.
The MUX6 field is used during the seventh sample of a sequence
executed with Sample Sequencer 0 and specifies which of the
analog inputs is sampled for the analog-to-digital conversion.
Reserved bits return an indeterminate value, and should never be
changed.
The MUX5 field is used during the sixth sample of a sequence
executed with Sample Sequencer 0 and specifies which of the
analog inputs is sampled for the analog-to-digital conversion.
Reserved bits return an indeterminate value, and should never be
changed.
The MUX4 field is used during the fifth sample of a sequence
executed with Sample Sequencer 0 and specifies which of the
analog inputs is sampled for the analog-to-digital conversion.
Reserved bits return an indeterminate value, and should never be
changed.
The MUX3 field is used during the fourth sample of a sequence
executed with Sample Sequencer 0 and specifies which of the
analog inputs is sampled for the analog-to-digital conversion.
