UART Baud Rate Error (%)
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:
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.
Table 83 provides information about baud rate errors for popular baud rates and com-
monly used crystal oscillator frequencies for normal UART mode of operation.
