Web13 Briefly define register indirect addressing. 13 Briefly define displacement addressing. 13 What is the difference between postindexing and preindexing? 13 Immediate addressing is an addressing mode where the operand is directly specified in the instruction itself, rather than being stored in memory or in a register. Web16 sep. 2024 · 4. Register Indirect Addressing Mode. A register is used as a pointer to the data. If the data is inside the CPU, only registers R0 and R 1 are used for this purpose. R2 - R7 cannot be used to hold the address of an operand located in RAM when using indirect addressing mode. When RO and R 1 are used as pointers they must be preceded by … how to use pak choi in soup
