==== XWDC auto-addressing procedure ====
At the start of the procedure no SNPD devices have a NAD assigned

1 First auto-addressing LIN message
:1.1 All outputs (D<sub>2</sub>) are set to a high level, all pull-downs are turned off
:1.2 The first SNPD node is selected. It is identified by having the input D<sub>1</sub> low (hardwired).
:1.3 The selected node takes the address from the LIN configuration message
:1.4 The detected node turns on the pull-down at the output D<sub>2</sub>
2 Subsequent auto-addressing LIN messages
:2.1 The first non addressed SNPD node is selected. It is identified by having the input D<sub>1</sub> low (D<sub>2</sub> of previous node).
:2.2 The selected node takes the address from the LIN configuration message
:2.3 The detected node turns on the pull-down at the output D<sub>2</sub>
:2.4 Steps 2.1-2.4 are repeated until all slave nodes are assigned an address
3 All pull-ups and pull-downs are turned off completing the addressing procedure
