> FD 86 d | ADD A,(IY+d) | 9 (2,2,2,1,2) | A = A + (IY+d)

> #### 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 assembler views "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)."
