But the basic idea is that when a read or write occurs for a memory address, the microprocessor outputs the address on its bus. Hardware (called an 'address decoder') detects that the address is for a particular memory-mapped I/O device and enables that device as the target of the … Webmemory-mapped I/O. These I/O methods differ in how I/O ports are mapped into the 8086’s address spaces. Some microcomputer systems employ both kinds of I/O- that is, some peripheral ICs are treated as isolated I/O devices and others as memory- mapped I/O devices. Let us now look at each of these types of I/O. Isolated Input/ Output Method: cummins 6.7 isb fan clutch
