Topic: Microprocessors
In microcomputer, WAIT states are used to
- A. Make the processor wait during a DMA operation
- B. Make the processor wait during a power interrupt processing
- C. Make the processor wait during a power shutdown
- D. Interface slow peripherals to the processor
Answer: D. Interface slow peripherals to the processor
Explanation: WAIT states are inserted into the microprocessor's machine cycles to stall the CPU temporarily. This allows slower memory or peripheral I/O devices extra time to place data on the bus or read data from it.
