LIN Baud Rate Divider Least Significant Bits.
The 8 least significant bits for the baud rate divider. The 9th and most significant bit
is the DIV9 bit (LIN0MUL.0). The valid range for the divider is 200 to 511.
These bits are the baud rate prescaler bits.
These bits are the baud rate multiplier bits. These bits are not used in slave mode.
LIN Baud Rate Divider Most Significant Bit.
The most significant bit of the baud rate divider. The 8 least significant bits are in
LIN0DIV. The valid range for the divider is 200 to 511.
