This document discusses the addressing modes of the 8085 microprocessor. It introduces the 8085 and describes its key specifications. It then defines addressing modes as the method by which an instruction specifies the address of the source of data or destination of a result. Five addressing modes are described - direct, register, register indirect, immediate, and implicit. The document concludes that the addressing mode depends on the bytes in the instruction and allows the instruction to specify operands and data addresses.

3. Introduction to 8085Introduction to 8085
It was introduced in 1977.
It is 8-bit microprocessor.
It has 8 bit Data Bus.
It has a 16 bit Address Bus.
It contains 6200 transistors approx.
Addressable Memory is 64 KB.
40 pins IC.
Operating at a Clock Frequency of 5 MHz.

12. ConclusionConclusion
Conclusion is that, the method by which the
address of source of data or the address of
destination of result is given in the
Instruction is called Addressing Mode.
And, whatever the Addressing modes is there,
the instruction consist of the operand,
address of the source data, and
destination of the result.
Or, we can say that Addressing modes for the
instructions is also depends on that what byte
of instruction we input.
