11.7 Z8 IMMEDIATE DATA ADDRESSING (IM)
Immediate data is considered an “addressing mode” for the pur-
poses of this discussion. It is the only addressing mode that does
not indicate a register or memory address as the source operand.
The operand value used by the instruction is the value supplied
in the operand field itself. Because an immediate operand is part
of the instruction, it is always located in the Program Memory
address space (Figure 11-8).
