8085 Programming: Store 8 bit data in Memory

8085 Programming

Program 1:

MVI A, 52H : Store 32H in the accumulator

STA 4000H : Copy accumulator contents at address 4000H

HLT : Terminate program execution

Program 2:

LXI H : Load HL with 4000H

MVI M : Store 32H in memory location pointed by HL register pair (4000H)

HLT : Terminate program execution

Note: The result of both programs will be the same. In program 1 direct addressing instruction is used, whereas in program 2 indirect addressing instruction is used.
