Register Configuration
After setting the LSTART bit, confirm that the RXDSF flag is set to 1 before Synch Break input starts.
Before changing LIN operation modes, temporarily stop the LIN operation (LINE bit = 0).
Refer to Figure 17.5 Exam ple of Header Field Transm ission Flow chart (1) and Figure 17.9 Exam ple of
Header Field Reception Flow chart (2).
