  • What is instruction format of 8086?

    000[BX] + [SI]AL AX001[BX] + [DI]CL CX010[BP] + [SI]DL DX011[BP] + [DI]BL BX
  • How many instruction format are there in 8086?

    The instruction format also contains other fields known as operand fields •The CPU executes the instruction using the information which reside in these fields •There are six general formats of instructions in 8086 instruction set.
  • What is MOV instruction format in 8086?

    MOV: Data transfer Register/memory to/from register. This format is similar to register to register transfer. The difference is in mod field. For register to register, mod = 11 For register to/from memory with no displacement, mod = 00.
  • The 8086 has 14 16 bits registers. AX, BX, CX, DX, SI, DI, BP, SP, CS, DS, SS, ES, IP and the flags register. The last two are only accessed indirectly.
