Arithmetic and Logical Instruction Set

• Add content of one register and another register and store the result in next register

• Subtract content of memory location 5000H from 5001H and store result in 5002H

• Add 16-bit data from register pair B and D and store result at HL pair

• Load 00H into register B and 10H into register C. Increment content of register B and Decrement content of register C. Store result at memory locations 4000H and 4001H

• Load 16-bit data of register pair from another register pair and store result

• WAP to perform AND, OR and XOR operation between 51H and A2H. Store the AND result at 9000H, OR at 9001H and XOR at 9002H

• WAP in 8085 microprocessor showing masking of lower and higher nibbles of 8-bit number. Store the original number in 7007H, masked lower nibble in 7008H and masked upper nibble in 7009H

• WAP in 8085 microprocessor to set the D6, D1 and D0 bits of 8 bits data A8H and store the result in memory location 1010H

• WAP to RESET the D4, D3, D2 and D0 bits of 8-bit data 3DH and store the result in register B
