Addressing modes of 80864/3/2023 ![]() ![]() If data is present at the 16-bit address mentioned in the instruction, it is called direct addressing mode. For example,Īre two instructions following immediate addressing mode as the data 01H or 04H is directly present in the instruction itself. If data is present in the instruction itself, it is called immediate addressing mode. Instructions like ADD, SUB are sequential control flow instructions whereas instructions like JUMP, CALL are control transfer instructions.Īddressing Modes for sequential control flow instructions Intel 8086 microprocessor supports eight different addressing modes for sequential control flow instructions. are located and control returns to the current position after execution of all the instructions in the predefined address, they are what called as control transfer instructions. ![]() ![]() On the other hand, if a set of instructions are such that control shifts from one instruction to a predefined address where instructions for a particular procedure etc. If a set of instructions are such that control shifts from one instruction to its next instruction, they are referred to as sequential control flow instructions. There are two types of instructions called sequential control flow instructions and control transfer instructions. operands in the memory, different modes called addressing modes are used. ![]() Addressing Modes Address can be defined as a location in the memory. ![]()
