INSTRUCTION SET OF 8085
The vocabulary of the machine

8 2/6/2023
The Vocabulary of the Machine
“If u want to interact/make friendship with some body then the best way to
do it, is to learn the language the person speaks”.
The language microprocessor and microcontroller understand is know as
machine language and the machine language each word is known as instruction.
The set of instruction which a microprocessor understands is known as
instruction set.
The instruction is nothing but the set of binary numbers i.e. 0 and 1 inside a
memory.

9 2/6/2023
It is nothing but an abbreviation or mental image or symbol and this symbolic
name signifies what operation it performs.
Mnemonics

10 2/6/2023
Instruction Set (Cont…)
An instruction is a command given to the microprocessor to perform a
specific operation on given data.
Each instruction contain two parts
(a) operational code (op code)
(b) operand
NOTE: Intel 8085 microprocessor have 74 instruction and 246 op-code.

11 2/6/2023
The instruction set can be categorized into FIVE different groups.
1. Data transfer group.
2. Arithmetic group.
3. Branch group.
4. Logic group.
5. Stack, input/out put and machine control group.
Instruction Set (Cont…)

12 2/6/2023
The data transfer group of instructions load given data into registers,
move data between register and move data between registers and memory
location.
A. Register to register.
B. Register to memory.
C. Memory to register.
D. Immediate data to register.
E. Immediate data to memory.
F. Exchange
Data Transfer Group

13 2/6/2023
1. MOV R1, R2 (Move the content of one register to another)
Example :
i. MOV A, B
(This instruction will copy the data from source register “B” into accumulator “A”)
ii. MOV B, A
(It will copy the data from accumulator “A” into destination register “B” )
2. MOV R , M (Move the content of memory to register)
Example:
LXI H, 2000H (It will load 20H into H register and 00H into L register)
MOV B, M (The 8-bit data content of the memory location as pointed by HL
register pair will be moved to the register “B”. It is an instruction to load
register “B” with the 8-bit data from a specified memory location whose 16-bit
address is in HL register pair.)
HLT

14 2/6/2023
3. MOV M, R (Move the content of register to memory)
Example:
i. MOV M, C
(Moves the content of register C to the memory location whose address is in H-L pair)
4. MVI R , DATA (Move immediate data to register)
Example:
i. MVI A , 05H
(This instruction will load 05H into accumulator)
