Hi Magnus,

I'm still interest on any code to bring my C53 or C8252 into the non programmable state. Until now I found no way to do this. I let always the EA pin fixed on VCC for internal program execution.

I understand not, whats your problem on reading from SPI.
If I remember right, you must send a read command as the 1. byte and than read the data byte by transfering a 2. byte. This 2. byte was ignored by the MAX3100.
