HEADER
A LIN cluster consists of one master task and several slave tasks. A master node contains the
master task as well as a slave task. All other nodes contain a slave task only.
Figure 15-1. LIN cluster with one master node and “n” slave nodes
The master task decides when and which frame shall be transferred on the bus. The slave
tasks provide the data transported by each frame. Both the master task and the slave task are
parts of the Frame handler
A frame consists of a header (provided by the master task) and a response (provided by a
slave task).
The header consists of a BREAK and SYNC pattern followed by a PROTECTED IDENTIFIER.
The identifier uniquely defines the purpose of the frame. The slave task appointed for provid-
ing the response associated with the identifier transmits it. The response consists of a DATA
field and a CHECKSUM field.
Figure 15-2. Master and slave tasks behavior in LIN frame
The slave tasks waiting for the data associated with the identifier receives the response and
uses the data transported after verifying the checksum.
