PD70F3792, 70F3793 have an SBF (Sync Break Field) transmission/reception control function to enable use
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 (INTUC0T) 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 reduce costs of automotive networks.
LIN communication is single-master communication, and up to 15 slaves can be connected to the
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.

The INTUC0T signal is also output at the start of each SBF transmission.
