ADD , ADI (Add Immediate), SUB , INR (Increment Register), and DCR (Decrement Register).
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 ). 8085 Instruction Set Gaonkar
JMP (Unconditional Jump), JC (Jump on Carry), and CALL / RET (Subroutine handling). ADD , ADI (Add Immediate), SUB , INR
Opcode followed by a 16-bit address or data (e.g., LDA 2050H ). ADI (Add Immediate)
MOV (Move), MVI (Move Immediate), LDA (Load Accumulator), and STA (Store Accumulator).
These perform bitwise manipulation, essential for masking and testing specific bits.
HLT (Halt), NOP (No Operation), and instructions to enable/disable interrupts.
