Gaonkar details that instructions vary in length based on their complexity: Only an opcode (e.g., MOV A, B ). 2-Byte: Opcode followed by 8-bit data (e.g., MVI A, 32H ).
The 8085 performs 8-bit addition, subtraction, increment, and decrement. 8085 Instruction Set Gaonkar
These instructions manage the state of the microprocessor itself. Gaonkar details that instructions vary in length based
Unlike data transfer, these instructions update the Flag Register (Carry, Zero, Sign, etc.) to reflect the result’s status. 3. Logic Operations detailed in Microprocessor Architecture
These operations are the foundation of data handling, allowing the CPU to stage information for processing. 2. Arithmetic Operations
This structured approach, detailed in Microprocessor Architecture, Programming, and Applications with the 8085 , bridges the gap between binary "machine language" and human-readable "assembly language". (PDF) Microprocessor Ramesh S Gaonkar - Academia.edu
