Definition
This pin is a high-voltage input used to wake-up the LIN1 from Sleep mode.
This pin is the transmitter input of the LIN1 interface which controls the state of the bus
output.
This bidirectional pin represents the LIN1 single-wire bus transmitter and receiver.
This bidirectional pin represents the LIN2 single-wire bus transmitter and receiver.
This pin can have two main functions: controlling an external switchable voltage
regulator having an inhibit input, or driving an external bus resistor connected to LIN2 in
the master node application.
This pin is the receiver output of the LIN2 interface, which reports the state of the bus
voltage to the MCU interface.
This pin controls the operation mode of the LIN2 interface.
This pin is a high-voltage input used to wake-up the LIN2 device from Sleep mode.
This pin is the device ground pin.
This pin is the transmitter input of the LIN2 interface, which controls the state of the bus
output.
This pin is device battery level power supply.
