AIM: To perform addition of two 8 – bit numbers using 8051 instruction set.

ALGORITHM:

1. Clear C – register for Carry
2. Get the data immediately .
3. Add the two data
4. Store the result in memory pointed by DPTR

PROGRAM:

        ORG	4100
        CLR	C
        MOV	A,#data1
        ADD	A,#data2
        MOV	DPTR,#4500
        MOVX	@DPTR,A 
HERE:	SJMP	HERE

OBSERVATION:

Input:	66
	23
Output:	89 (4500)

RESULT:
