Set Gaonkar: 8085 Instruction

ANA (Logical AND), ORA (Logical OR), XRA (Logical XOR), and CMP (Compare).

These operations are the foundation of data handling, allowing the CPU to stage information for processing. 2. Arithmetic Operations

ADD , ADI (Add Immediate), SUB , INR (Increment Register), and DCR (Decrement Register). 8085 Instruction Set Gaonkar

Unlike data transfer, these instructions update the Flag Register (Carry, Zero, Sign, etc.) to reflect the result’s status. 3. Logic Operations

HLT (Halt), NOP (No Operation), and instructions to enable/disable interrupts. ANA (Logical AND), ORA (Logical OR), XRA (Logical

MOV (Move), MVI (Move Immediate), LDA (Load Accumulator), and STA (Store Accumulator).

They enable complex logic like loops and conditional execution by modifying the Program Counter (PC) . 5. Machine Control Operations Arithmetic Operations ADD , ADI (Add Immediate), SUB

Instructions like RLC (Rotate Left) and RRC (Rotate Right) shift bits within the accumulator, which is critical for serial data processing. 4. Branching Operations
