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