Addressing modes(contd..)
1.Immediate mode
-operand is given explicitly in the instruction.
-E.g. Move #200,R0
-Can be used to represent constants.
2.Register, Absolute and Immediate mode contained either the address of the operand itself.
3.Some instructions provide information from which the memory address of the operand can be determined
-That is,they provide the "Effective Address" of the operand.
-They do not provide the operand or the address of the operand explicitly.
4.Differant ways in which "Effective Address" of the operand can be generated.
