A microprocessor carries out a number of operations while processing data. A simple microprocessor like 8085 can read data, write data and do some simple arithmetic operations on it. But all these operations are carried out in smaller steps and in synchronization with the clock signal. The timing diagram represents the clock cycle and duration, delay, content of address bus and data bus, type of operation i.e., read/write/status signals. There are some output signals in 8085 that tell us about the processes going on inside the microprocessor. These signals tell us about the type of machine cycle going on at any particular time. If we understand the function of these signals, then we can put them together, and their combined values will give us a complete picture of what stage the microprocessor is in. It’s like detective work. The presentation can provide you adequate details.
