The contents of register r is loaded to the memory location specified by the contents of the HL register pair. The r symbol 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 contents of register pair HL specify memory location $2146 and register B contains byte $29, then upon the execution of
LD (HL),B
memory address $2146 also contains $29.
