3, 2 — Reserved These bits are always read as 0. The write value should always
be 0.

4 LIOS LIN Interrupt Output Select 0: LIN interrupt is used.
1: Transmission interrupt, successful reception interrupt, and
reception status interrupt are used.

R/W
Set the LMDn register when the OMM0 bit in the LMSTn register is 0 (LIN reset mode).
LMD[1:0] bits (LIN/UART mode select bits)
The LMD bits select the LIN/UART module mode.
To use the LIN/UART module as a LIN slave, set these bits to 10b or 11b.
With 10b set, the LIN/UART module operates in LIN slave mode with auto baud rate.
With 11b set, the LIN/UART module operates in LIN slave mode with fixed baud rate.
LIOS bit (LIN interrupt output select bit)
The LIOS bit selects the number of interrupt outputs from the LIN/UART module.
With 0 set, the LIN interrupt is generated from the LIN/UART module.
With 1 set, the transmission interrupt, successful reception interrupt, and reception status interrupt are generated from the
LIN/UART module.
For each interrupt source, refer to 17.9 Interrupts.
LRDNFS bit (LIN reception data noise filtering disable bit)
The LRDNFS bit enables or disables the noise filter when receiving data.
With 0 set, the noise filter is enabled when receiving data.
With 1 set, the noise filter is disabled when receiving data.
