8085 Programming : ADDITION OF 16BIT NUMBERS




8085 Programming






ADDITION OF TWO 16BIT NUMBERS SUM 16 BITS OR MORE


Manually strore 1st 16 bit no in the memory location C050 & C051 in reverse order

Manually store 2nd 16 bit no in the memory location C052 & C053 in reverse order

Result is stored in C053, C054 & C055 in reverse order



          LHLD C050

         XCHG

         LHLD C052

         MVI C,00

         DAD D

         JNC AHEAD

         INR C



AHEAD:   SHLD C054

        MOV A,C

        STA C056

        HLT



EXAMPLE-> A645+9B23=014168

STORE-> C050=45,C051=A6,C052=23,C053=9B

Answer-> C054=68,C055=41,C056=01

// 45H,A6H,23H,9BH
