WebWhen processor use the central memory (RAM) to communicate with peripheral devices then it is called Memory mapped I/O. In this case, all external devices are mapped in the same way as RAM and ROM are mapped to the processor. That means all the peripheral devices can be accessed as similar we access memory.

WebThis allows ports to be I/O-mapped rather than memory-mapped. We let port addresses be just 8 bits since this allows 256 input ports and 256 output ports – more than enough. It also allows us to specify the address in the out (N),a instruction in just 1 byte, instead of the 2 bytes that would have to be provided if we used a 16-bit port address.
