LDAX(Load accumulator indirect): - The contents of the designated register pair point to a memory location. This instruction copies the contents of that memory location into the accumulator. The contents of either the register pair or the memory location are not altered. Eg: - LDAX B. 5.LXI(Load register pair immediate): - The

Instructions, which are used to transfer data from one register to another register, from memory to register or register to memory, come under this group. Examples are: MOV, MVI, LXI, LDA, STA etc. When an instruction of data transfer group is executed, data is transferred from the source to the destination without altering the
Another form of the MOV instruction is MOV reg,immdata which means read the immediate data (i.e. constant) immdata into register reg. Note that if the addr in LEA reg,addr is just a constant (i.e. a fixed offset) then that LEA instruction is essentially exactly the same as an equivalent MOV reg,immdata
assembler instructions. mov ax,SEG _DATA ; set up data segment mov ds,ax. mov ah,4ch ; terminate program int 21h. END ProgramStart. This is only valid for simple assembler programs that are of the small, non-memory resident variety. For larger programs the .MODEL directive can be LARGE or HUGE or COMPACT.

Opcode, Operand, Meaning, Explanation. MOV. Rd, Sc. M, Sc. Dt, M. Copy from the source (Sc) to the destination(Dt). This instruction copies the contents of the source register into the destination register without any alteration. Example ? MOV K, L. MVI. Rd, data. M, data. Move immediate 8-bit. The 8-bit data is stored in the
Answer / nairita. MOV: This instruction copies the contents of the source register into the destination register; the contents of the source register are not altered. If one of the operands is a memory location, its location is specified by the contents of the HL registers. Example: MOV B, C or MOV B, M
The instructions LDA and STA move data between memory and A . The instruction MOV either moves data between registers, or between a register and a memory location specified by HL . LDA and STA are used when the address can be resolved at assembly/link time. MOV is used when the memory
