8085 Addressing Modes & Interrupts
Addressing Modes in 8085 These are the instructions used to transfer the data from one register to another register from the memory to the register and from the register to the memory without any alteration in the content Addressing modes in 8085 is classified into 5 groups − Immediate addressing mode
What are logical instructions in 8085 microprocessor?
In 8085 microprocessor, the destination operand is generally the accumulator. Logical instructions are the instructions which perform basic logical operations such as AND, OR, etc. In 8085 microprocessor, the destination operand is always the accumulator. Here logical operation works on a bitwise level. a result of executing a branch instruction.
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.
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.

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.
