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? Questions 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. 3.0 2.0 1.0 0.0 -1.0 SPLDecoder -2.0 -3.0 -4.0 -5.0 -1.0 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0
