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

ANA (Logical AND), ORA (Logical OR), XRA (Logical XOR), and CMP (Compare). 8085 Instruction Set Gaonkar

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 ). Unlike data transfer, these instructions update the Flag

These perform bitwise manipulation, essential for masking and testing specific bits. Unlike data transfer

These allow the program to change its execution sequence based on specific conditions or unconditionally.

These instructions manage the state of the microprocessor itself.

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