14.3.1. Direct Addressing Mode

Try these first

1. 1.

   What does direct addressing mode do?

   Hint

   Think about how the memory location is accessed.

2. 2.

   How many steps are involved in immediate addressing mode?

   Hint

   Recall the summary of the steps for each addressing mode.

3. 3.

   Which addressing mode fetches data directly from a specified memory address?

   • A) Immediate Addressing
   • B) Direct Addressing
   • C) Indirect Addressing

   Hint

   Focus on how each mode specifies operand access.

4. 4.

   True or False: Immediate addressing always requires a memory read operation.

   • True
   • False

   Hint

   Consider the definition of immediate addressing.

5. 5.

   Create a flowchart illustrating the execution steps for both direct and indirect addressing modes.

   Hint

   Focus on how each mode differs fundamentally in accessing the operand.

6. 6.

   Given an assembly instruction using indirect addressing, write out the execution sequence with control signals.

   Hint

   Decomposing the instruction into clear steps will help clarify the sequence.
