8085 Addressing Modes & Interrupts

Addressing modes in 8085 is classified into 5 groups − Immediate addressing mode In this mode the 8/16-bit data is specified in the instruction itself as one of its operand For example: MVI K 20F: means 20F is copied into register K Register addressing mode In this mode the data is copied from one register to another

ADDRESSING MODES OF 8085

Intel 8085 uses the following addressing modes: Direct Addressing Mode Register Addressing Mode Register Indirect Addressing Mode Immediate Addressing Mode Implicit Addressing Mode Direct Addressing Mode In this mode the address of the operand is given in the instruction itself LDA is the operation 2500 H is the address of source

PDF	Addressing Modes of Microprocessor – 8085 There are 5 types of addressing modes - Immediate Addressing Mode (IAM) Direct Addressing Mode (DAM) Register Direct Addressing Mode (RDAM) Register Indirect Addressing Mode (RIAM) Implicit Addressing Mode (IPAM) Immediate Addressing Mode

What is a data addressing mode in a microprocessor?
These data are called its operands and may be part of the instruction, reside in one of the internal registers of the microprocessor, stored at an address in memory or held at an I/O port, to access these different types of operands, the 8086 is provided with various addressing modes (Data Addressing Modes).
What are the addressing modes in 8085?
Addressing modes in 8085 is classified into 5 groups − In this mode, the 8/16-bit data is specified in the instruction itself as one of its operand. For example: MVI K, 20F: means 20F is copied into register K. In this mode, the data is copied from one register to another. For example: MOV K, B: means data in register B is copied to register K.
How many addressing modes does the 8051 provide?
The 8051 provides a total of five distinct addressing modes. They are as follows: 1. Immediate addressing mode 2. Register addressing mode 3. Direct addressing mode 4. Register indirect addressing mode 5. Indexed addressing mode
What is 8085 instruction set?
The 8085 instruction set can be classified into the following five functional headings. Data Transfer Instructions:Includes the instructions that moves (copies) data between registers or between memory locations and registers. In all data transfer operations, the content of source register is not altered.

Features of The Addressing Modes in The 8085 Microprocessor

Immediate addressing:In immediate addressing mode, the operand is a constant value that is part of the instruction. The immediate addressing mode is used for instructions that require a fixed value

Advantages of Addressing Modes in 8085 Microprocessor

Versatility: The 8085 microprocessor supports several addressing modes, which allows for a wide range of memory access and manipulation options.Efficient memory usage: Different addressing modes allow for efficient use of memory, reducing the memory footprint of programs and making the best use of available memory.Easy to use:The addressing modes are easy to use, making it simple for programmers to write and execute complex programs.Improved performance: The use of different addressing modes can improve the performance of programs, as the correct addressing mode can be chosen to match the specific requirements of the program. geeksforgeeks.org

Disadvantages of Addressing Modes in 8085 Microprocessor

Complexity:The various addressing modes can be complex, making it difficult for programmers to choose the correct mode for a given task.Overhead:The use of different addressing modes can result in additional overhead, as the microprocessor must perform additional operations to access memory.Debugging difficulties:Debugging programs that use multiple addressing modes can be difficult, as the programmer must keep track of the different modes used in each memory access.Limitations: The addressing modes are limited by the size of the program counter and the memory address space, which can impact the performance of large programs. geeksforgeeks.org
