i need help with parts 2 and 3 

**Read this article about the SPI bus and answer the three questions below. Submit your answers to Canvas.** [Introduction to SPI Interface](#) **Question 1** What is meant by "Full Duplex" when referring to a serial interface? **Question 2** In Figures 2, 3, 4, and 5, the designation of the state of the MISO signal is "Hi-Z" before and after the SS signal is low. This means the output driving the signal is turned completely off and not driving the signal either high or low. "Hi-Z" means "High Impedance". Also, in the figures, the designation of the state of the MOSI signal is "XXX" before and after the SS signal is low. This means the state of the signal is "Unknown" or "Don't Care". If there are multiple Slaves on the bus, why must a Slave turn off the driver (Hi-Z) on their MISO signal when their SS signal is high and the Slave is not selected? **Question 3** The article defines four SPI Modes or configurations numbered 0, 1, 2, and 3. Which mode corresponds to the setup shown in this diagram? The blue trace is the data signal and the red trace is the clock. **Diagram Explanation:** The diagram shows two traces: - **Blue Trace (Data Signal):** The trace oscillates between a low and high state, indicating changes in the data signal being transmitted. - **Red Trace (Clock):** The trace consists of consistent, periodic pulses indicating the clock cycles. Each cycle has a clear high and low state transition. The traces together represent the synchronization of data transmission (blue) with clock pulses (red), which are key to identifying the correct SPI mode being used.
