Data Transfer Instructions | 8085 programs | Microprocessor
Welcome to our in-depth tutorial on data transfer instructions in the 8085 microprocessor! In this video, we will cover the following essential instructions: MOV, MVI, LDA, STA, LDAX, STAX, LXI, and XCHG. Understanding these instructions is fundamental for anyone learning about the 8085 microprocessor, whether you're a student, hobbyist, or professional.
What You'll Learn:
MOV Instruction: Learn how to move data between registers and memory locations.
MVI Instruction: Understand how to move immediate data to a register or memory location.
LDA Instruction: Discover how to load data from a specified memory location into the accumulator.
STA Instruction: Find out how to store the accumulator's data into a specified memory location.
LDAX Instruction: Explore how to load data from memory into the accumulator using register pairs.
STAX Instruction: Learn how to store the accumulator's data into memory using register pairs.
LXI Instruction: Understand how to load 16-bit data into register pairs.
XCHG Instruction: Discover how to exchange data between the H-L and D-E register pairs.
Detailed Breakdown:
MOV (Move):
Syntax: MOV destination, source
Moves data from the source register to the destination register.
Example: MOV B, C (Copies the contents of register C to register B).
MVI (Move Immediate):
Syntax: MVI register, data
Moves immediate data to the specified register.
Example: MVI A, 32H (Moves the immediate value 32H to register A).
LDA (Load Accumulator Direct):
Syntax: LDA 16-bit address
Loads data from the specified memory address into the accumulator.
Example: LDA 2000H (Loads data from memory location 2000H into the accumulator).
STA (Store Accumulator Direct):
Syntax: STA 16-bit address
Stores the data from the accumulator into the specified memory address.
Example: STA 2000H (Stores the data from the accumulator into memory location 2000H).
LDAX (Load Accumulator Indirect):
Syntax: LDAX register pair
Loads data from the memory location pointed by the register pair into the accumulator.
Example: LDAX B (Loads data from the memory location pointed by the BC register pair into the accumulator).
STAX (Store Accumulator Indirect):
Syntax: STAX register pair
Stores the data from the accumulator into the memory location pointed by the register pair.
Example: STAX D (Stores the data from the accumulator into the memory location pointed by the DE register pair).
LXI (Load Register Pair Immediate):
Syntax: LXI register pair, 16-bit data
Loads 16-bit immediate data into the specified register pair.
Example: LXI H, 1234H (Loads the immediate value 1234H into the H-L register pair).
XCHG (Exchange Register Pair):
Syntax: XCHG
Exchanges the contents of the H-L register pair with the D-E register pair.
Example: XCHG (Swaps the data between H-L and D-E register pairs).
