- The Concept: Explain how an external peripheral can request the bus using the HOLD pin.
- The Action: The 8085 responds with HLDA (Hold Acknowledge), effectively disconnecting itself from the bus so data can move directly from a disk drive to memory without slowing down the CPU. Gaonkar uses this to explain system efficiency.

Introduction: The Golden Standard of 8085 Learning microprocessor 8085 ppt by gaonkar
The 8085 is an 8-bit general-purpose microprocessor. It is capable of addressing 64KB of memory. It features a built-in clock generator and system controller, making it more efficient than its predecessors. Key Features 8-bit data bus and 16-bit address bus. Operates on a single +5V power supply. Clock frequency of 3 MHz (8085A). 74 instruction sets with 5 addressing modes. Integrated serial I/O and interrupt control. Internal Architecture Blog Title: The Ultimate Guide to Finding &
- T1:
ALEgoes high. Lower byte of address (AD0-AD7) is placed on the bus.IO/M= 0 (Memory).RD= 1 (inactive). - T2:
ALEgoes low (latching the address).RD= 0 (active read). The selected memory places the Opcode on the data bus. - T3: The processor reads the data bus.
RDgoes high (inactive). - T4: The processor decodes the instruction.
- Clear, authoritative introduction to the Intel 8085 microprocessor aimed at undergraduate electronics/EE/CS students.
- Covers architecture, instruction set, timing diagrams, interrupt structure, and interfacing basics in a logically ordered progression.
Use the slides to memorize the pin diagram and opcodes. Use the book (or YouTube tutorials) to understand why the 8085 does what it does. The Concept: Explain how an external peripheral can
