Note:

The UART must be disabled when updating the Baud Rate registers because the high and
low registers must be written independently.
The LIN-UART data rate is calculated using the following equation for standard 
UART operation:
The LIN-UART data rate is calculated using the following equation for LIN mode UART
operation:
For a given LIN-UART data rate, the integer baud rate divisor value is calculated using the
following equation for standard UART operation:
For a given LIN-UART data rate, the integer baud rate divisor value is calculated using the
following equation for LIN mode UART operation:
The baud rate error relative to the appropriate baud rate is calculated using the following
equation:
For reliable communication, the LIN-UART baud rate error must never exceed 5 percent.
