WebMemory Interfacing When we are executing any instruction, we need the microprocessor to access the memory for reading instruction codes and the data stored in the memory. For this, both the memory and the microprocessor requires some signals to read from and write to … Web9 mei 2024 · They function as address lines for the first part of the clock cycle, and data lines for the later part. Also important for addressing is a pin called BHE, "bus high enable". A0 also functions as an "enable" pin, as we'll see in a moment. If the 8086 wants to read the word at addresses 124-125, It puts 124 on A19:A0, and sets BHE to low.
