The (IX+d) operand (i.e., the contents of Index Register IX summed with two’s-complement displacement integer d) is loaded to register r, in which r identifies registers A, B, C, D, E, H, or L, assembled as follows in the object code:
| Register | r | Hex |
|---|---|---|
| A | 111 | $77 |
| B | 000 | $70 |
| C | 001 | $71 |
| D | 010 | $72 |
| E | 011 | $73 |
| H | 100 | $74 |
| L | 101 | $75 |
None
If the C register contains byte $1C, and Index Register IX contains $3100, then the instruction
LD (IX+$6),C
performs the sum $3100+$6 and loads $1C to memory location $3106
