Dear NXP Team,
I find out Unique ID(UID) in document RM of MPC5744P. But I still have some question about UTEST&UID:
1. How can I identify the chip, MPC5744P/MPC5748G? Is it UID on UTEST flash of MPC5744P/MPC5748G? Is it global unique chip id?
2. Can UID of MPC5744P on UITest change?
RM says the UID on UTEST flash is programmed during factory test. Can the UTEST flash be programmed by user or programmer after leaving factory?(see figure1)
3. Where is the UID description of MPC5748G?
I can just find the location of UTEST flash of MPC5748G. Do you have more document about how to identify the details?
