The LIN-UART data rate is calculated using the following equation for standard UART
modes. For LIN protocol, the baud rate registers must be programmed with the baud period
rather than 1/16 baud period.
The UART must be disabled when updating the baud rate registers because 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:
