Addressing mode of 8086 :
Addressing mode specify a way of locating operands or data. Depending on the data types used the memory addressing modes and in the instruction , any instruction may belong or some may not belong to one or more addressing modes. Thus the addressing modes explained the types of operands and the way they are accessed for executing an instruction. We will present the addressing modes of the instructions here depending on theirtypes.The instructions can be categorizedaccording to the flow of instruction execution as (i) Control transfer instructions and (ii) Sequential control flow instructions.
On the other hand, the control transfer instructions and transfer control to some predefined address or the address somehow indicated in the instruction, after their execution. For an example, CALL,INT, JUMP and RET instructions fall under this category.
Sequential control flow instructions transfer control after execution to the next instruction appearing immediately after it (in the sequence)in the program. For instance, the, logical, arithmetic,processor control and data transfer instructions are sequential control flow instructions.
