Thank u williB, now we know its the software who tells the MC to do the operation.

I have on this system a group of memory (RAM 32K*8, EPROM 32K*8, E2PROM8K*8).
In the data memory range (0000H,…….,0FE00H) we have in the memory some not used spaces:
77FFH …..8000H = Can not be used . why this range, was not clear to me.
In the documentation written : the apparent memory conflict between E2PROM and RAM sharing the same address range (0000H….77FFH) is avoided by using the /PSEN signal for address decoding. What conflict, I look at the memory figures the RAM range b/n (0000H….77FFH), and the E2PROM range b/n (8000H…9FFFH).
hope what I wrote is clear.
