r <- (IX+d)
The (IX+d) operand (i.e., the contents of Index Register IX summed with two’s-complement displacement integer d) is loaded to register r, in which r identifies registers A, B, C, D, E, H, or L, assembled as follows in the object code:
If Index Register IX contains the number $25AF, the instruction
allows the calculation of the sum $25AF+$19, which points to memory location $25C8. If this address contains byte $39, the unstruction results in Register B also containing $39.
