Which of the following statements is true?
Which of the following statements is true?
Show Hint
- Memory-Mapped I/O: Common address space. Peripherals are treated like memory locations, allowing them to use all standard memory manipulation instructions.
- I/O-Mapped I/O: Separate address space. Requires dedicated IN/OUT instructions.
