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 sample sequence 3 has the lowest priority. When reconfiguring sequence
priorities, each sequence must have a unique priority or the ADC behavior is inconsistent.

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 SS3 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. ADC behavior is not consistent if two or more fields
are equal.
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 SS2 field contains a binary-encoded value that specifies the priority
encoding of Sample Sequencer 2.
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 SS1 field contains a binary-encoded value that specifies the priority
encoding of Sample Sequencer 1.
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 SS0 field contains a binary-encoded value that specifies the priority
encoding of Sample Sequencer 0.
