LIN communication by using microcontroller

This section explains practical LIN communication using microcontrollers.
In the starter kit, the microcontroller and LIN transceiver IC (TJA1020T) are connected as shown in
"Figure 5-7 LIN circuit".In the microcontroller, SOT sends, SIN receives, and SCK is the port that
controls the transceiver IC. Sending and receiving signals flow on the bus via the LIN transceiver IC.
