These instructions move data between registers or between memory and registers without altering the content of the source.
HLT (Halt), NOP (No Operation), and instructions to enable/disable interrupts.
Opcode followed by a 16-bit address or data (e.g., LDA 2050H ). 8085 Instruction Set Gaonkar
JMP (Unconditional Jump), JC (Jump on Carry), and CALL / RET (Subroutine handling).
These operations are the foundation of data handling, allowing the CPU to stage information for processing. 2. Arithmetic Operations These instructions move data between registers or between
They enable complex logic like loops and conditional execution by modifying the Program Counter (PC) . 5. Machine Control Operations
ADD , ADI (Add Immediate), SUB , INR (Increment Register), and DCR (Decrement Register). NOP (No Operation)
These instructions manage the state of the microprocessor itself.
