The contents of resister r are loaded to the memory address specified by the sum of the contents of Index Register IY and d, a two’s-complement displacement integer. The r symbol is specified according to the following table.
| 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 $48, and Index Register IY contains $2A11, then the instruction
LD (IY+$4),C
performs the sum $2A11+$4 and loads $48 to memory location $2A15
