Receiving Data using Interrupt-Driven Method
6. Read data from the LIN-UART Receive Data register. If operating in

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 opera-
tion:
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
3. Execute a DI instruction to disable interrupts.
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)
7. Write the device address to the Address Compare register (automatic multiprocessor
8. Write to the LIN-UART Control 0 register to:
