What is the function of IO/M signal in the 8085?

  Shared By: Agatha Miller    Date: Nov 27    Category: Assembly Language    Views: 6286

Answer:

It is a status signal. It is used to differentiate between memory locations and I/O operations. When this signal is low (IO/M = 0) it denotes the memory related operations. When this signal is high (IO/M = 1) it denotes an I/O operation.
