4 / 35 page IS25WD020/040 Integrated Silicon Solution, Inc.- www.issi.com Rev. F 07/31/2013 4 SPI MODES DESCRIPTION Multiple IS25WD020/040 devices can be connected on the SPI serial bus and controlled by a SPI Master, i.e. microcontroller, as shown in Figure 1. The devices support either of two SPI modes: Mode 0 (0, 0) Mode 3 (1, 1) The difference between these two modes is the clock polarity when the SPI master is in Stand-by mode: the serial clock remains at “0” (SCK = 0) for Mode 0 and the clock remains at “1” (SCK = 1) for Mode 3. Please refer to Figure 2. For both modes, the input data is latched on the rising edge of Serial Clock (SCK), and the output data is available from the falling edge of SCK. Figure 1.
