CHAPTER 14 LIN-UART
14.6 Operations of LIN-UART and LIN-UART
Setting Procedure Example
14.6.5 Bidirectional Communication Function
(Normal Mode)
Normal serial bidirectional communication can be performed in operating mode
0 or 2. Asynchronous mode can be selected in operating mode 0 and
synchronous mode in operating mode 2.
■ Bidirectional Communication Function
To operate the LIN-UART in normal mode (operating mode 0 or 2), the settings shown in
Figure 14.6-10 are required.
Figure 14.6-10 Settings of LIN-UART Operating Mode 0 and Operating Mode 2
● Inter-CPU connection
When using bidirectional communication, connect two CPUs as shown in Figure 14.6-11.
