Microprocessor 8085 programming (Memory Location)<\/h2>\n

1. Sixteen bytes of data are stored in a memory location at 1050H to 105FH. Replace each data byte by FF.<\/strong><\/p>\n

LXI H, 1050H
\nMVI C, 10H
\nL1: MVI M, FFH
\nINX H
\nDCR C
\nJNZ L1
\nHLT<\/p>\n

2. Add two numbers located at 3030H and 4040H. Display sum on Port 1. If the carry is generated, <\/strong>display it on Port 2. Store sum on 5050H.<\/strong><\/p>\n

LDA 3030H
\nMOV B, A
\nLDA 4040H
\nADD B
\nSTA 5050H
\nOUT PORT 1
\nJNC L1
\nMVI A, 01H
\nOUT PORT 2
\nL1: HLT<\/p>\n

3. Write an Assembly Language Program that retrieves data located at 2050H and it displays if it is even and stores FFH on that location if it is odd.<\/strong><\/p>\n

LDA 2050H
\nANI 01H
\nJNZ L1
\nLDA 2050H
\nOUT PORT 1
\nHLT<\/p>\n

L1:\u00a0 MVI A, FFH
\nSTA 2050H
\nHLT<\/p>\n

4. Sixteen data are stored in a memory location at 1050H to 105FH. Transfer the entire block of data to a new location starting at 1070H.<\/strong><\/p>\n

LXI H, 1050H
\nMVI C, 10H
