The break must contain a dominant value of 13 bits or more to ensure proper
synchronization of slave nodes.
In the LIN communication, a slave task is required to be synchronized at the beginning
of the protected identifier field of frame. For this purpose, every frame starts with a
sequence consisting of a break field followed by a synch byte field. This sequence is
unique and provides enough information for any slave task to detect the beginning of a
new frame and be synchronized at the start of the identifier field.
Upon entering LIN communication, a connection is established and the transfer speed
(baud rate) of the serial communication partner (host) is automatically synchronized in
the following steps:
Note: Re-synchronization and setup of baud rate are always done for every Master
Data Sheet
STEP 1: Initialize interface for reception and timer for baud rate measurement
STEP 2: Wait for an incoming LIN frame from host
STEP 3: Synchronize the baud rate to the host
STEP 4: Enter for Master Request Frame or for Slave Response Frame
Request Header or Slave Response Header LIN frame.
