A region that informs each ECU of the starting of header transmission
by sending dominant signals for a given period of time.
Synchronization
region
A region that synchronizes the transmission cycle of each ECU
connected to the LIN bus line (the slave ECU matches its
communication speed to that of the master ECU).
Identifier region
A region that stores an ID to call the slave ECU defined by the LIN
protocol. The number of bytes for the data region is also defined in this
region.
Response
Data region
A region to store the control data used by ECU that is called by the
header
Checksum region
A region for checking errors in data content The sending-end ECU
calculates data region value according to the specified computing
equation, and the result is stored in this filed. The receiving-end ECU
detects the transmission error based on the checksum filed value.
