IMMEDIATE DATA ADDRESSING (IM)
UM012811-0904
Figure 15. Relative Addressing
Immediate data is considered an “addressing mode” for this discussion. It is the only
addressing mode that does not indicate a register or memory address as the 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 Pro-
gram Memory address space (see Figure 16).
