Instruction Reference Manual 45Description• LD (IX+d),HL: Loads the data in register L into the memory location whose address is thesum of the data in index register IX and a displacement value d. Then, loads the data in register Hinto 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 forthe Z180.• LD (IX+d),n: Loads the 8-bit constant n into the memory location whose address is the sumof 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) intothe memory location whose address is the sum of the data in index register IX plus a displace-ment value d.LD (IX+d),HLLD (IX+d),nLD (IX+d),rOpcode Instruction Clocks OperationF4 d LD (IX+d),HL 11 (2,2,1,3,3) (IX + d) = L; (IX + d + 1) = HDD 36 d n LD (IX+d),n 11 (2,2,2,2,3) (IX + d) = n——DD 77 dDD 70 dDD 71 dDD 72 dDD 73 dDD 74 dDD 75 dLD (IX+d),rLD (IX+d),ALD (IX+d),BLD (IX+d),CLD (IX+d),DLD (IX+d),ELD (IX+d),HLD (IX+d),L10 (2,2,2,1,3)10 (2,2,2,1,3)10 (2,2,2,1,3)10 (2,2,2,1,3)10 (2,2,2,1,3)10 (2,2,2,1,3)10 (2,2,2,1,3)10 (2,2,2,1,3)(IX + d) = r(IX + d) = A(IX + d) = B(IX + d) = C(IX + d) = D(IX + d) = E(IX + d) = H(IX + d) = LFlags ALTD I/OS Z L/V C F R SP S D- - - - •
