Transmitting Data using Interrupt-Driven Method
5. Check the TDRE bit in the LIN-UART Status 0 register to determine if the Transmit
6. If in MULTIPROCESSOR mode, write the LIN-UART Control 1 register to select the
7. Write the data byte to the LIN-UART Transmit Data register. The transmitter

9. To transmit additional bytes, return to Step 4.
The LIN-UART Transmitter interrupt indicates the availability of the Transmit Data register
to accept new data for transmission. Follow the steps below to configure the LIN-UART for
interrupt-driven data transmission:
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 Transmitter interrupt
5. If multiprocessor mode is appropriate, write to the LIN-UART Control 1 register to
6. Write to the LIN-UART Control 0 register to:
7. Execute an EI instruction to enable interrupts.
Data register is empty (indicated by a 1). If empty, continue to Step 6. If the Transmit
Data register is full (indicated by a 0), continue to monitor the TDRE bit until the
Transmit Data register becomes available to receive new data.
