LIN stands for Local Interconnect Network and is a low-speed (1 to 20 kbps) serial communication protocol designed to
Communication of LIN is single-master communication and up to 15 slaves can be connected to one master.
The slaves are used to control switches, actuators, and sensors, which are connected to the master via LIN.
Usually, the master is connected to a network such as CAN (Controller Area Network).
A LIN bus is a single-wire bus to which nodes are connected via transceiver conforming to ISO9141.
According to the protocol of LIN, the master transmits a frame by attaching baud rate information to it. A slave receives
Figure 14-92 outlines a transmission operation of LIN.
Notes 1. The baud rate is set so as to satisfy the standard of the wakeup signal and data of 00H is transmitted.
