content of is pushed into the stack and now top pointer point to D. (IV)SUB B [ACC]-[B]--->[[ACC] Here the content of B is substracted with content of accumlator. (v) POP D Here the content of D is popped and then action ois performed and then result is stored/pushed back in [TOP]. 3. (I)MVI B Immidiate addressing mode (II)MOV D,B Register addressing mode. (III)ADD B register addressing mode. 4. (i)NOP : 00 i.e 00 00 00 00 (ii)ORA B : B0 i.e 10 11 00 00 (iii)MOV D,L :55 i.e 01 01 01 01 (iv)MOV B,E :43 i.e. 01 00 00 11 (v)ADD D : 82 i.e 10 00 00 10 5. Here 8085 has a combination of all the organisation .It performs task with general purpose register, accumulator& stack. Here ,it is a combination of general register organisation ,stack organisation and single accumulator organisation. OBSERVATION: CONCLUSION: VIVA VOCE QUESTIONS: 1. What the total no of pins of 8085? 2. What is the address space of 8085? 3. What are the different types of instructions available in 8085? 4. What are the general purposes registers available in 8085? 5. What are the flags available in 8085?
