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 UART, set these bits to 01b.
With 01b set, the LIN/UART module operates as UART.
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.
