Register 21: ADC Sample Sequence Input Multiplexer Select 2 (ADCSSMUX2),
offset 0x080
This register defines the analog input configuration for each sample in a sequence executed with
Sample Sequencer 2. This register is 16-bits wide and contains information for four 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.
The MUX3 field is used during the fourth sample of a sequence executed
with the Sample Sequencer and specifies which of the analog inputs is
sampled for the analog-to-digital conversion.
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.
The MUX2 field is used during the third sample of a sequence executed
with the Sample Sequencer and specifies which of the analog inputs is
sampled for the analog-to-digital conversion.
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.
The MUX1 field is used during the second sample of a sequence
executed with the Sample Sequencer and specifies which of the analog
inputs is sampled for the analog-to-digital conversion.
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.
The MUX0 field is used during the first sample of a sequence executed
with the Sample Sequencer and specifies which of the analog inputs is
sampled for the analog-to-digital conversion.
