7.2.1.2 LIN slave node address assignment
The default slave Node Address (NAD) after power-on depends on the input levels of the
configuration pins C1, C2 and C3. These pins will be sampled directly after the power-on
event. The relation between the configuration pins and the NAD is shown in
Table 4.
In case a different NAD is necessary the assign NAD command has to be used. The
assign NAD request is carried out if the Service Identifier (SID) in the third data byte of the
MasterReq is the assign NAD request and the fourth to seventh data bytes are the LIN
supplier codes of Philips (0x0011) and UJA1023 function ID (0x0000).
