> DD 96 d | SUB (IX+d) | 9 (2,2,2,1,2) | A = A - (IX + d)
> FD 96 d | SUB (IY+d) | 9 (2,2,2,1,2) | A = A - (IY + d)

> #### Description

> Subtracts the data whose address is:

> - the sum of IX and the 8-bit signed displacement d, or
> - the sum of IY and d.

> from A. The result is stored in A.

> The Rabbit 4000 assembler views "SUB A,(IX+d)" and "SUB (IX+d)" as equivalent instructions.The same is true for "SUB A,(IY+d)" and "SUB (IY+d)."
