To set up the LIN clock, set the clock divider for the peripheral clock, which is being used for the LIN Component. The LIN baud rate is calculated by:
Baud Rate = (Peri Clock)/ (16* Divider value).
So, Divider value= (Peri Clock)/ (16* Baud Rate).
Here 16 is the oversampling factor that is fixed in Traveo II device. So, set the divider value correctly to get the appropriate baud rate. For instance, for a peripheral clock of 80 MHz, the required baud rate is 19.3 kbps; since you are using a 16-bit integer divider, the divider value is 260 (0x104). You need to set the value of the INT16_DIV of PERI_DIV_16_CTL_x register to divider value minus one. In this example, set the value of the INT16_DIV of PERI_DIV_16_CTL_x register to 259 (0x103) (260-1).
