This microprocessor constains following instructions:
A. Load and Store:
1. MOV-This instruction copies the contents of the source register into the destination register without any alteration.
2. MVI-The 8-bit data is stored in the destination register or memory.
3. LXI-The instruction loads 16-bit data in the register pair designated in the register or the memory.
4. LDA-The contents of a memory location, specified by a 16-bit address in the operand, are copied to the accumulator.
5. STA-The contents of the accumulator are copied into the memory location specified by the operand.
6. LHLD-The instruction copies the contents of the memory location pointed out by the address into register L and copies the contents of the next memory location into register H.
7. SHLD-The contents of register L are stored in the memory location specified by the 16-bit address in the operand and the contents of H register are stored into the next memory location by incrementing the operand.
8. STAX-The contents of the accumulator are copied into the memory location specified by the contents of the operand.
9. XCHG-The contents of register H are exchanged with the contents of register D, and the contents of register L are exchanged with the contents of register E.
B. Arithmetic:
1. ADD-The contents of the register or memory are added to the contents of the accumulator and the result is stored in the accumulator.
2. ADI-The 8-bit data is added to the contents of the accumulator and the result is stored in the accumulator.
3. SUB-The contents of the register or the memory are subtracted from the contents of the accumulator, and the result is stored in the accumulator.
4. INR-The contents of the designated register or the memory are incremented by 1 and their result is stored at the same place.
5. DCR-The contents of the designated register or memory are decremented by 1 and their result is stored at the same place.
6. INX-The contents of the designated register pair are incremented by 1 and their result is stored at the same place.
7. DCX-The contents of the designated register pair are decremented by 1 and their result is stored at the same place.
8. DAD-The 16-bit data of the specified register pair are added to the contents of the HL register.
9. SUI-The 8-bit data is subtracted from the contents of the accumulator & the result is stored in the accumulator.
C. Logical:
1. CMA-The contents of the accumulator are complemented. No flags are affected.
2. CMP-The contents of the operand (register or memory) are M compared with the contents of the accumulator.
D. Branching:
1. JMP-The program sequence is transferred to the memory address given in the operand.
2. JC-The program sequence is transferred to the memory address given in the operand when carry flag is 1.
3. JNC-The program sequence is transferred to the memory address given in the operand when carry flag is 0.
4. JZ-The program sequence is transferred to the memory address given in the operand when zero flag is 1.
5. JNZ-The program sequence is transferred to the memory address given in the operand when zero flag is 0.
E. Extra:
An additional command SET is used to set data into memory location.
SYNTAX: SET <Memory Address>, <2 Byte Hexadecimal Data>
eg: SET 2500, FF

You can also use inbuilt debugger to debug your 8085 program. The debugger has following 6 functionality/ commands:
1. break or b : It will set breakpoint on given line number.
Eg: break 10 or b 10
2. run or r : It will run the program until end of code or breakpoint is encountered. Eg: run or r
3. step or s : It will run the program one instruction at a time. Eg: step or s
4. print or p : It will print value of register, flags, current line number or memory location.
To print value of register use print or p . Eg: print A or p A.
To print value flag use print or p flag. Eg: print flag or p flag.
To print current line number use print or p loc. Eg: print loc or p loc.
To print value of memory location use print or p x. Eg: print x2000 or p x2000.
5. Quit or q : Quits the debugger.
Eg: quit or q
6. help : It will show all the commands of the debugger.
Eg: help
