Instruction Reference Manual 45
Description
•
LD (IX+d),HL:
Loads the data in register L into the memory location whose address is the
sum of the data in index register IX and a displacement value d. Then, loads the data in register H
into the memory location whose address is the sum of the data in index register IX and a dis-
placement value d plus 1. This instruction is implemented for the Rabbit and is not available for
the Z180.
•
LD (IX+d),n:
Loads the 8-bit constant n into the memory location whose address is the sum
of index register IX and a displacement value d.
•
LD (IX+d),r:
Loads the data in register r (any of the registers A, B, C, D, E, H, or L) into
the memory location whose address is the sum of the data in index register IX plus a displace-
ment value d.
