could you please more specify your requirement?
Please check the link below. There are the most useful documents you need.
There is also EABI document, which can be useful
and instruction set documents
thank you for your reply.
I'll specify my question: I'm an Application Designer in Lynxar Technologies (www.lynxartech.com), a leader company in the field of In-System Programming, and a Customer asked us to support the NXP MPC56xx Family. So I need the documentation about the in-system progamming protocol and the flash programming procedure to implement the algorithms on our programmer.
I'll check the documentation you linked, if would need something more, I'll let you know.
Thank you again for the support
