CHAPTER  11   SERIAL  INTERFACE  UART6 

User’s Manual  U16898EJ3V0UD 

177

Remark

  LIN stands for Local Interconnect Network and is a low-speed (1 to 20 kbps) serial communication 

protocol intended to aid the cost reduction of an automotive network. 

 

LIN communication is single-master communication, and up to 15 slaves can be connected to one 
master.   

 

The LIN slaves are used to control the switches, actuators, and sensors, and these are connected to the 
LIN master via the LIN network. 

 

Normally, the LIN master is connected to a network such as CAN (Controller Area Network).   

 

In addition, the LIN bus uses a single-wire method and is connected to the nodes via a transceiver that 
complies with ISO9141. 

 

In the LIN protocol, the master transmits a frame with baud rate information and the slave receives it and 
corrects the baud rate error.  Therefore, communication is possible when the baud rate error in the slave 
is 

±

15% or less. 

 
Figures 11-1 and 11-2 outline the transmission and reception operations of LIN.

Notes 1.

  The wakeup signal frame is substituted by 80H transmission in the 8-bit mode. 

 

2.

  The synchronous break field is output by hardware.  The output width is equal to the bit length set by 

bits 4 to 2 (SBL62 to SBL60) of asynchronous serial interface control register 6 (ASICL6) (see 

11.4.2 

(2) (h)  SBF transmission

). 

 

3.

  INTST6 is output on completion of each transmission.  It is also output when SBF is transmitted. 

 

Remark

  The interval between each field is controlled by software.
