2.2.2 LIN Communication

Each of the four LIN channels have headers and test points assigned to all TXD, RXD, and LIN pins. Reference Section 2.3 for specific details on the headers and test points. All test points are also labeled on the PCB silkscreen.

To adequately exercise and evaluate the LIN channels, use a function generator capable of at least 100kHz, and from 0V to 5V square. Connect this to one of the four TXD pins. Observe the output on the corresponding LIN pin with the voltage level swinging between ground and VSUP. Additionally, see the output on the corresponding RXD pin with the voltage level swinging between ground and VIO. Use an oscilloscope capable of at least 10V per division and 50µs per division.

Before attempting to evaluate LIN communication, verify that the SLP pin is in the logic-low state. This places the transceiver into Normal mode where LIN communication is enabled. If a waveform is asserted on TXD and the corresponding LIN pin is not responding or at ground level, then the device is not in Normal mode. This means that the SLP pin is asserted high; verify the state of the SLP pin before exercising any of the LIN channels.
