Loading a memory location using indexed addressing for the destination
and immediate addressing for the source requires four bytes. For example,
LD (IX - 15), 21H
appears as:
Notice that with any indexed addressing the displacement always follows
directly after the Op Code.
Table 7 specifies the 16-bit load operations. The extended addressing
feature covers all register pairs. Register indirect operations specifying
the stack pointer are the
these instructions is
that the stack pointer is automatically decremented and incremented as
each byte is pushed onto or popped from the stack respectively. For
example, the instruction
