I/O Read Machine Cycle
- A reader I/O cycle is performed by the processor to read a data byte from an I/O port or peripheral that is I/O mapped in the system.
- The processor needs 3T states to execute this machine cycle.
Timing Diagram 8085 Microprocessor
A time diagram is a graphical representation where the 8085 instruction timing diagram represents the execution time of each instruction in graphical format. In this article, we will be Going Through the Timing Diagram, We will go through Different Machine Cycles Such as Opcode Fetch, Memory Read, Memory Write, I/O Read, and I/O Write, Then we will go through the Timing Diagram of Some Instructions such as MVI, STA, and INR, At last, we will conclude our Article with Applications and Some FAQs.
