Timing Diagram of ADD M & MOV Instructions in 8085 | Opcode Fetch + Memory Read Cycle Explained

In this video, we have explained the complete Timing Diagram of ADD M and MOV Instructions of the 8085 Microprocessor.
Both instructions are 1-byte instructions, but ADD M requires a Memory Read Cycle, while MOV may or may not involve memory depending on the operand.
✨ Topics Covered:
✔ ADD M instruction format
✔ Why ADD M requires a Memory Read cycle
✔ MOV instruction format (MOV r, r and MOV r, M)
✔ Difference between register-to-register and register-to-memory operations
✔ Opcode Fetch Cycle – Timing Diagram
✔ Memory Read Cycle (for ADD M / MOV r, M)
✔ T-states explanation
✔ ALE, IO/M, RD, WR signal behavior
✔ Internal execution of arithmetic and data transfer operations in 8085
This lecture is extremely useful for B.Tech, Diploma, GATE, ESE, and competitive exam students.
