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 4000/5000 assemblers view "SUB A,(IX+d)" and "SUB (IX+d)" as equivalent instructions.The same is true for "SUB A,(IY+d)" and "SUB (IY+d)."
