| The addressing with displacement calculated the sum of two values: the index register and the constant. As shown in figure {{ref>avr_addr_8}}, the operand address is the result of the q displacement contained in the instruction word, added to the Y or Z pointer. Rd/Rr specify the destination or source register. An example of indirect addressing with displacement is accessing an element of a previously defined data table. | The addressing with displacement calculates the sum of two values: the index register and the constant.
