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.
