Hello,
You need to download the LIN stack from this link [8-bit Small Package SG MCUs | NXP Semiconductors] in the section of Software, with the name [LIN2.x and SAE J2602 Stack], when you install this at the root of the installation in the documentation file you can find a User manual.
The s9s08sg16 is the same as the 32 and has all support.
Best regards,
Pavel.
