What does direct addressing mode do?
Think about how the memory location is accessed.
How many steps are involved in immediate addressing mode?
Recall the summary of the steps for each addressing mode.
Which addressing mode fetches data directly from a specified memory address?
Focus on how each mode specifies operand access.
True or False: Immediate addressing always requires a memory read operation.
Consider the definition of immediate addressing.
Create a flowchart illustrating the execution steps for both direct and indirect addressing modes.
Focus on how each mode differs fundamentally in accessing the operand.
Given an assembly instruction using indirect addressing, write out the execution sequence with control signals.
Decomposing the instruction into clear steps will help clarify the sequence.
