Hello Jashan,

Based on the Reference Manual, the procedure to initially start up the MSCAN module out of reset is as follows:

1. Assert CANE
2. Write to the configuration registers in initialization mode
3. Clear INITRQ to leave initialization mode

Besides, I would like to recommend the MSCAN driver for Kinetis EA devices.

In case you are interested please refer to the following link:

KEA |Kinetis KEA Automotive MCUs|Freescale

Finally, the following document could be useful because of the basic concepts.

Bosch Controller Area Network (CAN)

Please let me know if this material is useful for you, in case it is not I will be glad to help.

Have an excellent day.

David
