The contents of the Index (register pair IX) Register is added to a two's complement displacement d to point to an address in memory. A logical exclusive-OR operation is performed between the contents of this memory address and the contents of the Accumulator. The result is stored in the Accumulator.
| S | is set if result is negative, otherwise it is reset. |
| Z | is set if result is 0, otherwise it is reset. |
| H | is reset. |
| P/V | is set if parity even, otherwise it is reset |
| N | is reset. |
| C | is reset. |
If the Accumulator contains $96 (1001 0110), Index Register IX contains $1000, and memory location $1005 contains $5D (0101 1101), then upon the execution of
XOR (IX+$05)
the Accumulator contains $CB (1100 1011).
