Receiving Data Using the Interrupt-Driven Method
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
2. Enable the LIN-UART pin functions by configuring the associated GPIO port pins
3. Execute a
4. Write to the Interrupt Control registers to enable the LIN-UART Receiver interrupt
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
8. Write to the LIN-UART Control 0 Register to:
9. Execute an
The LIN-UART is now configured for interrupt-driven data reception. When the
LIN-UART Receiver interrupt is detected, the associated ISR performs the following:
1. Checks the LIN-UART Status 0 register to determine the source of the interrupt-error,
2. If the interrupt is due to data available, read the data from the LIN-UART Receive
3. Execute the IRET instruction to return from the ISR and await more data.
