Analog-to-Digital Converter (ADC)
Register 14: 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
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
8th Sample Input Select
The MUX7 field is used during the eighth sample of a sequence executed
with the sample sequencer. 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 0x1 indicates the input
is AIN1.
0
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0x0
7th Sample Input Select
The MUX6 field is used during the seventh sample of a sequence
executed with the sample sequencer. It specifies which of the analog
inputs is sampled for the analog-to-digital conversion.
0
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0x0
6th Sample Input Select
The MUX5 field is used during the sixth sample of a sequence executed
with the sample sequencer. It specifies which of the analog inputs is
sampled for the analog-to-digital conversion.
0
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
