| Chapter | Title | Key Concepts | |---------|-------|----------------| | 1 | Microprocessor Evolution | 4004 → 8085 → x86; stored program concept | | 2 | 8085 Architecture | ALU, register array (BC, DE, HL, SP, PC), flag register, internal bus | | 3 | 8085 Pin Description & Timing | Multiplexed AD0–AD7, A8–A15; RD, WR, IO/M , clock; machine cycle/state | | 4 | Programming Fundamentals | Opcode/operand; addressing modes (immediate, register, direct, indirect, implicit) | | 5 | Instruction Set Classification | Data transfer, arithmetic, logical, branch, stack/machine control | | 6 | Assembly Language Programming | Structure of assembly program; labels, directives (ORG, EQU, DB, DS) | | 7 | Counter & Time Delay | Loops; register pair as counter; using NOP & nested loops for delay | | 8 | Stack & Subroutines | PUSH/POP; CALL/RET; passing data via registers/memory | | 9 | Code Conversion & BCD/ASCII | Binary ↔ BCD; 7-segment; ASCII ↔ binary | | 10 | Interrupts | Vectored vs non-vectored; TRAP, RST 5.5, 6.5, 7.5; SIM/RIM | | 11 | Interfacing I/O Devices | Memory-mapped vs isolated I/O; 8255 PPI (mode 0, 1, 2) | | 12 | Advanced Interfacing | 8253/8254 (timer), 8279 (keyboard/display), 8259 (PIC) | | 13 | Applications | Traffic light controller; temperature monitor; stepper motor driver |

– A step-by-step introduction to assembly language , detailing the 8085 instruction set, addressing modes, and software development cycles (fetch, decode, execute). | Chapter | Title | Key Concepts |

LXI H, 3000H ; source address MOV A, M INX H ADD M INX H MOV M, A HLT This is where the rubber meets the road

: Case studies including digital clocks and traffic light controllers. Optimized for the keyword phrase “R

Perhaps the most practical section of the text is Part III: Interfacing. This is where the rubber meets the road. Gaonkar explains how to connect the CPU to the outside world.
