Register 8: ADC Sample Sequencer Priority (ADCSSPRI), offset 0x020
This register sets the priority for each of the sample sequencers. Out of reset, Sequencer 0 has the
highest priority, and Sequencer 3 has the lowest priority. When reconfiguring sequence priorities,
each sequence must have a unique priority for the ADC to operate properly.

Reset Description
0x0000.0
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.
0x3
SS3 Priority
This field contains a binary-encoded value that specifies the priority
encoding of Sample Sequencer 3. A priority encoding of 0 is highest
and 3 is lowest. The priorities assigned to the sequencers must be
uniquely mapped. The ADC may not operate properly if two or more
fields are equal.
0x0
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.
0x2
SS2 Priority
This field contains a binary-encoded value that specifies the priority
encoding of Sample Sequencer 2. A priority encoding of 0 is highest
and 3 is lowest. The priorities assigned to the sequencers must be
uniquely mapped. The ADC may not operate properly if two or more
fields are equal.
0x0
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.
0x1
SS1 Priority
This field contains a binary-encoded value that specifies the priority
encoding of Sample Sequencer 1. A priority encoding of 0 is highest
and 3 is lowest. The priorities assigned to the sequencers must be
uniquely mapped. The ADC may not operate properly if two or more
fields are equal.
0x0
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
