This type of interfacing is known as I/O interfacing. Microprocessor needs to Identify I/O devices with binary number.
WebWith the 8085, there are two methods to interface I/O devices; I/O mapped I/O and memory-mapped I/O. Both of these methods have their perks and snags. This is an important concept. So pay attention and understand the difference between the two methods. We’ll revisit this in the ARM Cortex M course.
