CHAPTER 14 LIN-UART
14.6 Operations of LIN-UART and LIN-UART
Setting Procedure Example
14.6.7 LIN Communication Function
In LIN-UART communication, a LIN device can be used in a LIN master system
or a LIN slave system.
■ LIN Master/Slave Mode Communication Function
Figure 14.6-16 shows the required settings for the LIN communication mode (operating mode
3) of the LIN-UART.
Figure 14.6-16 Settings of LIN-UART Operating Mode 3 (LIN)
● LIN device connection
Figure 14.6-17 shows an example of communication in a LIN bus system.
The LIN-UART can operate as a LIN master or a LIN slave.
