7. Return to Step 5 to receive additional data.
The LIN-UART receiver interrupt indicates the availability of new data (as well as error
conditions). Follow the steps below to configure the LIN-UART receiver for interrupt-
driven operation:
1. Write to the LIN-UART baud rate high and low byte registers to set the appropriate
2. Enable the LIN-UART pin functions by configuring the associated GPIO port pins for

4. Write to the interrupt control registers to enable the LIN-UART receiver interrupt and
5. Clear the LIN-UART receiver interrupt in the applicable interrupt request register.
6. Write to the LIN-UART control 1 register to enable MULTIPROCESSOR (9-bit)
