Hi,

I was looking for documentation about the PowerPC cores in the MPC5777M (e200z710n3 / e200z425Bn3) to set up eg the internal timebase register and decrement counter, check other SFRs, ...

I found these two

e200z446n3

https://www.nxp.com/docs/en/reference-manual/e200z4RM.pdf 

e200z760n3

https://www.nxp.com/docs/en/reference-manual/e200z760RM.pdf 

but not ones exactly for the e200z710n3 or e200z425Bn3 - are the z446 and z760 close enough to be useful? Is there more specific documents for the other cores? 

Thanks,

Jacob

Unfortunately, core reference manuals only exist for core variants used on MPC55xx/56xx devices.

Core variants used with MPC57xx devices are only described in MPC57xx device reference manuals. For instance, MPC5777MRM, specifically in chapters 13-15.

 

Following documents exist comparing cores to each other:

Also following presentation could be useful:

In case specific details is needed to consult, please create new case and we’ll try to help you:

I was looking for full information on the e200z425 core also. I've been able to be sure exactly what assembler opcodes it supports for floating point maths. Is there a definitive reference that tells me exactly which instructions are available?

I also found that the S32DS compiler is emitting opcodes that do not appear to be listed in the VLE documents.

Confused!

Following 3 documents should cover all opcodes:

http://www.nxp.com/files/32bit/doc/ref_manual/EREF_RM.pdf
http://www.nxp.com/files/32bit/doc/ref_manual/VLEPEM.pdf
http://www.nxp.com/files/32bit/doc/ref_manual/SPEPEM.pdf

However they may be some unsupported instructions for specific core variants.
