I found the Power Architecture e200 Core Self Test Software (SWE200-CST002E) on the MPC 5674f self test from NXP homepage.
I have confirmed through SWE200-CST002E description that SWE200-CST002E performs MCU core instruction tests.
In addition to MCU core instruction tests, I want to know if there is a library that supports the MPC 5674f self test.
