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.
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:
System Clock Frequency (Hz)
UART Data Rate (bits per second) =
16 x UART Baud Rate Divisor Value
The LIN-UART data rate is calculated using the following equation for LIN mode UART
operation:
System Clock Frequency (Hz)
UART Data Rate (bits per second) =
UART Baud Rate Divisor Value
For a given LIN-UART data rate, the integer baud rate divisor value is calculated using the
following equation for standard UART operation:
