I am looking for a way to use CAN FD with S12. From what I’ve found, one method is to use an external CAN controller. Products like the TCAN4551 or MCP2518FD can be used in a configuration like MCU - SPI - Controller to utilize FD CAN.
What I’m curious about is whether NXP has a module like this, and if there’s an easier method than SPI control.
