The contents of address (nn) are loaded to the low-order portion of register pair dd, and the contents of the next highest memory address (nn + 1) are loaded to the high-order portion of dd. Register pair dd defines BC, DE, HL, or SP register pairs, assembled as follows in the object code:
| Register | dd | Hex |
|---|---|---|
| BC | 00 | $4B |
| DE | 01 | $5B |
| HL | 10 | $6B |
| SP | 11 | $7B |
None
If address $2130 contains $65 and address $2131 contains $78, then upon execution of
LD BC,($2130)
the register pair BC will contain $7865.
