Addressing Model
As we have learned already that each instruction has two parts one is op code and another is operand. Op code specified the type of operations to be performed and operand is data on which the operation is to be performed. There are various ways of specifying the operands in8085 instructions. The way the operand is specified in the instruction is called addressing mode. 8085 micro processing has followings addressing modes.
Q. Consider the circuit configuration shown in Figure. Let V i = 1V, R 1 = 1000, R 2 = 2000, and A = 3. (a) Compute i 2 . (b) If R 1 changed to 500 , recompute i 2 .
