Do they have addresses of where they program flow should go?
Where is the address stored? In the internal RAM? Or is it in the main program body. I don't recall a instruction that it would contain it directly in the FLASH EPROM. Maybee its in something like the stack?

But I do rember something at the begining of on program for the 8515 wich may have been the address. But it was not in assembler, in wich I am intrested in. I am primarly interested in the 8052.

Is it in the stack?
