19.2.4. Baud Rate Calculations—Automatic Mode
If the LIN controller is configured for slave mode, only the prescaler and divider need to be calculated:
The following example calculates the values of these variables for a 24 MHz system clock:
Table 19.3 presents some typical values of system clock and baud rate along with their factors.
