Mpc555fl8mzp40 secured

[Mpc555]

Hi Im working on a tool development for the mpc555fl8mzp40 freescale chip. I normally read it by BDM with no problem, but Iv come accross a series that seems to be secured/locked. Need help by sorting out how.to access it. I would also like to develop a read and write protocoll for this by the RS485 on the Pcm. If some one here is capable of sorting out this to gether with me send me a PM and we can sort out the rest there. Thanks -mpc555-
