6.1 Stand-alone SPI

Stand-alone SPI is the default serial communication mode. This mode is selected when one driver is controlled and the other is inactive. In stand-alone SPI mode, each driver has its own nSCS signal, and only the nSCS of the selected driver functions. Hence, SPI communication is only possible with the selected driver. The Figure 6-1 shows the SPI connections for stand-alone SPI.
