7 — Reserved This bit is always read as 0. The write value should always
be 0.
R/W
Set the LBFCn register when the OMM0 bit in the LMSTn register is 0 (LIN reset mode).
UBLS bit (UART character length select bit)
The UBLS bit sets the length of a character of a UART communication frame.
With 0 set, a character of a frame is 8 bits long in communication.
With 1 set, a character of a frame is 7 bits long in communication.
Setting this bit is invalid when a character of a UART frame for communication is 9 bits long (the UEBE bit in the LUORn1
register is 1).
UBOS bit (UART transfer format select bit)
The UBOS bit sets the bit order of UART communication data.
With 0 set, data is transferred with the LSB first.
With 1 set, data is transferred with the MSB first.
USBLS bit (UART stop bit length select bit)
The USBLS bit sets the stop bit length in UART communication.
With 0 set, transmission is performed with 1 stop bit.
With 1 set, transmission is performed with 2 stop bits.
