Description

A is summed with the data whose address is:

• the sum of IX and the 8-bit signed displacement value d, or

• the sum of IY and the 8-bit signed displacement value d

The result is stored in A.

The Rabbit 4000/5000 assemblers view "ADD A,(IX+d)" and "ADD (IX+d)" as equivalent instructions. In the latter case, A is used even though it is not explicitly stated. The same is true for "ADD A,(IY+d)" and "ADD (IY+d)."
