The 8085 uses a multiplexed address/data bus (

Instructions like HLT (Halt) or NOP (No Operation). 4. Memory Interfacing and I/O

I can help you write a specific assembly language program or explain a timing diagram in detail.

A Gaonkar-style PPT categorizes instructions into five functional groups:

Contains five status flags: Carry (CY), Parity (P), Auxiliary Carry (AC), Zero (Z), and Sign (S). 3. The 8085 Instruction Set

One of Gaonkar's strengths is explaining how the processor "talks" to the outside world.

The remains a cornerstone of computer engineering education. For decades, students and professionals have relied on the teaching of Ramesh Gaonkar , whose textbook, Microprocessor Architecture, Programming, and Applications with the 8085 , is considered the "gold standard."

Gaonkar emphasizes the internal block diagram, which is the heart of any 8085 presentation.
