8085 – Demo Programs

Now, let us take a look at some program demonstrations using the above instructions −

Adding Two 8-bit Numbers

Write a program to add data at 3005H & 3006H memory location and store the result at 3007H memory location.

Problem demo −

(3005H) = 14H 
   (3006H) = 89H

Result −

14H + 89H = 9DH

The program code can be written like this − see more :  https://www.tutorialspoint.com/index.htm

LXI H 3005H   : "HL points 3005H" 
MOV A, M      : "Getting first operand" 
INX H         : "HL points 3006H" 
ADD M         : "Add second operand" 
INX H         : "HL points 3007H" 
MOV M, A      : "Store result at 3007H" 
HLT           : "Exit program"
