address mismatch occurs.
11 = The LIN-UART generates an interrupt request on all received data bytes for which
MPEN—MULTIPROCESSOR (9-bit) Enable
This bit is used to enable MULTIPROCESSOR (9-bit) mode.
0 = Disable MULTIPROCESSOR (9-bit) mode.
1 = Enable MULTIPROCESSOR (9-bit) mode.
MPBT—Multiprocessor Bit Transmit
This bit is applicable only when MULTIPROCESSOR (9-bit) mode is enabled.
0 = Send 0 in the multiprocessor bit location of the data stream (9th bit).
1 = Send 1 in the multiprocessor bit location of the data stream (9th bit).
DEPOL—Driver Enable Polarity
0 = DE signal is active High.
1 = DE signal is active Low.
BRGCTL—Baud Rate Generator Control
This bit causes different LIN-UART behavior depending on whether the LIN-UART
receiver is enabled (
When the LIN-UART receiver is not enabled, this bit determines whether the baud rate
generator issues interrupts.
0 = BRG is disabled. Reads from the baud rate high and low byte registers return the BRG
1 = BRG is enabled and counting. The BRG generates a receive interrupt when it counts
When the LIN-UART receiver is enabled, this bit allows reads from the baud rate registers
to return the BRG count value instead of the Reload Value.
0 = Reads from the baud rate high and low byte registers return the BRG Reload Value.
1 = Reads from the baud rate high and low byte registers return the current BRG count
value. Unlike the timers, there is no mechanism to latch the High byte when the Low byte is
read.
RDAIRQ—Receive Data Interrupt Enable
0 = Received data and receiver errors generates an interrupt request to the interrupt
1 = Received data does not generate an interrupt request to the interrupt controller. Only
IREN—Infrared Encoder/Decoder Enable
0 = Infrared encoder/decoder is disabled. LIN-UART operates normally.
1 = Infrared encoder/decoder is enabled. The LIN-UART transmits and receives data
down to 0. Reads from the baud rate high and low byte registers return the current
