Hi,

I agree that name of this application note could be quite confusing.

“LIN Enabled” here means hardware module that allows communicate over LIN.

In fact, software package AN4842 does not contain any LIN software. It is rather focused on other hardware initialization.

You have several options how to implement LIN software:

1. You can write your own LIN software. For that purpose, please look at attachment. There you can find simple example code for S12G which could be used as inspiration.

Note: S12ZVL has newer version of SCI module. You will have to update baud rate calculation (there missing now fBUS divider by 16).

Note: this simple LIN example was created according LIN 1.3 specification.

2. You can use Freescale LIN2.x and SAE J2602 Driver: http://www.freescale.com/files/microcontrollers/software/device_drivers/FSL_LIN_2.X_DRIVER.zip

3. You can use any of commercial solutions. For example: http://vector.com/

I hope it helps you.

Have a great day,
RadekS
