One Byte Instruction: These instructions in the category uses the implied addressing mode and register mode instruction.
The implied mode instruction does not use the operands, and the register mode uses the operand as one register.
CLC, CLD, STC, CMC, CBW, DAA, DAS, AAA, AAS, RET, CLI, HLT etc..What is the size of the instruction set in 8086?
8086 has more than 20,000 instructions. depending upon the addressing modes used for instructions. The Opcode stands for Operation Code. Every Instruction has a unique 6-bit opcode.
