I have built some development boards for educational use. They are capable of using ADUC8XX products.
Now I am interested in building a debugger for these devices, but unfortunately I did not find a description of the EA pin debugging.
Is there any way to get a protocol definition to build such a debugger? (RS232 to EA)
These products are very useful in education, because the 8052 core is easy to learn, and the ADUC8xx has used it in the best possible way.
Also the next step is much easier from this product. (like step to ARM based parts).
