Transmitting Data Using Interrupt-Driven Method
3. If MULTIPROCESSOR mode is required, write to the LIN-UART control 1 register
4. Write to the LIN-UART control 0 register to:
5. Check the
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
8. If MULTIPROCESSOR mode is required and MULTIPROCESSOR mode is enabled,
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
4. Write to the interrupt control registers to enable the LIN-UART transmitter interrupt
