Hello djg8623
Yes, but not specifically focused on the LPC54S018, the application note we have describes important considerations and connections between the TJA and a microcontroller.
Please take a look to:
TJA1145A Application-Hints
You can find it on our official website, scroll down to documents and select “secure files.”
TJA1145A

You will need to have a valid NDA with us to access secure files. If you don't have one, please open a ticket with us requesting an NDA to be signed. It will be assigned to the appropriate team, and you can continue with the process.
I hope this information has helped you, please let me know if you need help with anything else.
Have a great day and best of luck.
