Figures 15-4 and 15-5 outline the transmission and reception manipulations of LIN.
2. SBF output is performed by hardware.
3. 80H transfer in the 8-bit mode is substituted for the wakeup signal frame.
4. A transmission enable interrupt request signal (INTUAnT) is output at the start of each transmission.
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.

required, such adjustments can be performed using the UAnCTLn.UAnBRS7 to UAnCTLn.UAnBRS0
bits.
The INTUAnT signal is also output at the start of each SBF transmission.
