SPI Bus Interface

The Serial Peripheral Interface (SPI) bus is a synchronous serial communication interface used for short distance communication between various peripheral devices. The SPI bus interconnects a single master device with one or more slave devices.

The master device originates the data transmission by selecting a slave device and generating a clock. Data is transmitted in both directions simultaneously (full-duplex mode) or in one direction (half-duplex mode).

DLN adapters can operate as a master device (read SPI Master Interface). DLN-4S adapter can also operate as a slave device (read SPI Slave Interface).
