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
Reserved bits return an indeterminate value, and should
never be changed.
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.
Reserved bits return an indeterminate value, and should
never be changed.
The SS2 field contains a binary-encoded value that specifies
the priority encoding of Sample Sequencer 2.
Reserved bits return an indeterminate value, and should
never be changed.
The SS1 field contains a binary-encoded value that specifies
the priority encoding of Sample Sequencer 1.
Reserved bits return an indeterminate value, and should
never be changed.
The SS0 field contains a binary-encoded value that specifies
the priority encoding of Sample Sequencer 0.
